Are Procedural PHP Programmers Out Dated or Noobs as OOP Programmers Declare?

Procedural PHP programmers shouldn’t primarily outdated or thought-about “noobs” (novices) by OOP (Object-Oriented Programming) programmers. Every programming paradigms have their strengths and are acceptable for varied eventualities:

Procedural Programming:

Strengths: Procedural programming is simple, notably for smaller duties or scripts. It could be easier to know for inexperienced individuals and could also be additional atmosphere pleasant for positive duties that don’t require difficult object hierarchies.

Suitability: Procedural programming continues to be broadly used, notably in legacy codebases or in circumstances the place simplicity and quick implementation are priorities.

Object-Oriented Programming:

Strengths: OOP promotes code reusability, modularity, and scalability by the use of programs, objects, and inheritance. It’s well-suited for greater duties with difficult interactions between utterly totally different components.

Suitability: OOP is commonly utilized in fashionable PHP enchancment, notably for internet capabilities and duties that require sturdy code group and maintainability.

It’s necessary to acknowledge that programming paradigms are devices, and the collection of paradigm relies upon the actual requirements of the mission, the developer’s expertise, and totally different contextual parts. Every procedural and OOP programmers could also be extraordinarily knowledgeable and expert professionals.

Barely than labeling one paradigm as superior or outdated, it’s additional productive to cope with choosing the right methodology for each mission and repeatedly bettering talents and understanding in every procedural and OOP methods. Many builders are proficient in every paradigms and use them as complementary devices of their programming arsenal.

Setup integration exams in your WordPress Plugin

Some time in the past I created a primary article about unit exams almost 2 years in the past promising for a subsequent article on integration exams.

It took some time and my imaginative and prescient modified lots about exams throughout that time period.

Whereas writing the article on unit exams I used to be satisfied unit exams the place the primary to study to put in writing. Nevertheless, the fragility from theses exams made me change my thoughts as they weren’t giving sufficient outcomes for brand spanking new builders to persuade them to maintain utilizing them on the long run.

This is the reason I slowly modified my thoughts and at last began recommending to builders to start by specializing in essentially the most secure exams, integration exams, and that even when they’re extra complicated that unit exams to start out with.

All of that is what pushed me into writing this text to show the bottom of integration exams to builders wanting begin testing as creating the surroundings to check is usually essentially the most complicated half.

However first to know nicely what we might be doing you will need to get the principle variations between unit and integration exams.

The place unit exams are supposed to check the lessons or strategies individually as their identify let it guess, on the opposite aspect integration exams might be on an larger stage testing on the stage from the elements or options.

Being at options stage a bonus as now it’s potential to make use of enterprise assertions to check our code and it’s not any longer as much as us the developer to seek out instances from our exams.

On the similar time testing an larger stage additionally means larger abstraction main into extra flexibility to alter and fewer fragile exams.

Theses two factors makes theses exams a robust candidate to start out with and keep on with on the long run.

Now that know what are integration exams and why they’re your best option to start out with it’s time to set up the surroundings.

To not repeat the method I’ll contemplate that you have already got a composer mission initialized.

If it’s not the case you possibly can comply with the steps detailed in my article on Unit exams.

As setup a full surroundings for integration exams will be lengthy and complicated if performed manually we could have depend on some libraries to make the job for us.


As organising a growing surroundings is one thing that may be time losing WordPress group developed an automatic option to setup one.

As you may guess the identify from that software is wordpress/env however earlier than utilizing it be sure to have Docker installed.

As soon as that is performed the subsequent requirement is to have npm, the Node.js package deal supervisor, put in. If it’s not the case you could find a tutorial here.

With theses necessities met then the set up can begin.

First a brand new Node.js mission must be initialized on the root from our plugin mission with the next command:

npm init

This could generate a brand new package deal.json file into the folder.

Then the subsequent step might be to put in wordpress/env with the next command:

npm i wordpress/env

As soon as that is accomplished we must add the next content material inside package deal.json:

"scripts": {
"wp-env:start": "wp-env start",
"wp-env:stop": "wp-env stop",
"wp-env:destroy": "wp-env destroy"

Lastly the final step is to run the surroundings utilizing this command:

npm run wp-env:begin

If the whole lot goes effective then it ought to give the next output:

> wp-env:begin
> wp-env begin

⚠ Warning: couldn’t discover a .wp-env.json configuration file and couldn’t decide if ‘/var/www/testing-wp/internet/app/plugins/my_plugin’ is a WordPress set up, a plugin, or a theme.
WordPress growth web site began at http://localhost:8888
WordPress check web site began at http://localhost:8889
MySQL is listening on port 32770
MySQL for automated testing is listening on port 32769

✔ Carried out! (in 57s 413ms)

Course of completed with exit code 0


As soon as the event surroundings is settled the subsequent step is to setup the exams themselves.

For that we’ll delegate a lot of the work to the library wp-media/phpunit which gonna setup and reset the surroundings for us.

The primary to make use of wp-media/phpunit is to put in the library by operating the next command:

composer i wp-media/phpunit --dev


Within the WordPress ecosystem integration exams mocking filters is one thing actually frequent resulting from that it’s actually essential to ensure that operation is the much less verbose as potential.

The library wp-launchpad/phpunit-wp-hooks is completed to scale back the quantity of code to work together with a filter.

To put in that library that library you should run the next command:

composer i wp-launchpad/phpunit-wp-hooks --dev

As soon as that is performed the library is put in it’s now time to create base lessons for exams.

Make the bottom

Step one might be to create the namespace contained in the composer.json file from the mission by including the next code inside:

"autoload-dev": {
"psr-4": {
"MyPlugin\\Tests\\Integration\\": "Integration/"

If it’s not the case contained in the mission we must create a brand new folder exams and inside that folder one other one named Integration.

Then the subsequent step is to create file init-tests.php contained in the Integration folder. The target from that file is to setup wp-media/phpunit library by indication the place from the testing folder:

* Initializes the wp-media/phpunit handler, which then calls the rocket integration check suite.
require_once WPMEDIA_PHPUNIT_ROOT_DIR . 'vendor/wp-media/phpunit/Integration/bootstrap.php';
outline( 'WPMEDIA_IS_TESTING', true ); // Utilized by wp-media/.

As soon as that is performed then we have to create one other file bootstrap.php which gonna setup preliminary surroundings for our exams:

namespace MyPlugin\Exams\Integration;
outline( 'MY_PLUGIN_PLUGIN_ROOT', dirname( dirname( __DIR__ ) ) . DIRECTORY_SEPARATOR );
outline( 'MY_PLUGIN_TESTS_DIR', __DIR__ );

// Manually load the plugin being examined.

Lastly PHPUnit ought to be configured to execute the suite.

For that we must add the next content material into phpunit.xml.dist :

<?xml model="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi="" xsi:noNamespaceSchemaLocation="" bootstrap="init-tests.php" backupGlobals="false" colours="true" beStrictAboutCoversAnnotation="false" beStrictAboutOutputDuringTests="true" beStrictAboutTestsThatDoNotTestAnything="true" beStrictAboutTodoAnnotatedTests="true" convertErrorsToExceptions="true" convertNoticesToExceptions="true" convertWarningsToExceptions="true" verbose="true">
<protection includeUncoveredFiles="true">
<listing suffix=".php">../../inc</listing>
<testsuite identify="integration">
<listing suffix=".php">inc</listing>

Lastly we must create a base TestCase class.

It is going to be used to include logic which might be frequent to every of our exams.

For that we’ll add the next content material into TestCase.php the place my_prefix is your plugin prefix:

namespace MyPlugin\Exams\Integration;
use WPMedia\PHPUnit\Integration\TestCase as BaseTestCase;
use WPLaunchpadPHPUnitWPHooks\MockHooks;
summary class TestCase extends BaseTestCase
use MockHooks;
public operate set_up() 
dad or mum::set_up();
public operate tear_down()
operate getPrefix(): string
return 'my_prefix';
operate getCurrentTest(): string
return $this->getName();

Lastly the final step is so as to add the script to launch integration exams inside composer.json :

"test-integration": "\"vendor/bin/phpunit\" --testsuite integration --colors=always --configuration tests/Integration/phpunit.xml.dist --exclude-group AdminOnly,,",

And add the script to run the earlier script inside package deal.json the place my_plugin is the identify from the listing out of your plugin:

"integration": "wp-env run cli --env-cwd=wp-content/plugins/my_plugin composer run test-integration",

It’s now potential execute the exams by operating the next command:

npm run integration

If the whole lot goes effective you must have the next output:

> integration
> wp-env run cli --env-cwd=wp-content/plugins/my_plugin composer run test-integration

ℹ Beginning ‘composer run test-integration’ on the cli container.

> “vendor/bin/phpunit” –testsuite integration –colors=at all times –configuration exams/Integration/phpunit.xml.dist

Use fixtures

To completely perceive the significance of fixtures you possibly can test my earlier article about unit exams the place I already defined some great benefits of utilizing them.

On this article I’ll present find out how to make your exams appropriate with fixtures and this time it’s even easier than with unit exams as wp-media/phpunit is dealing with part of the complexity for us.

The primary half might be so as to add the Fixture folder contained in the exams folder.

Then the second half might be so as to add the logic to load fixtures contained in the TestCase class:

namespace MyPlugin\Exams\Integration;
use WPMedia\PHPUnit\Integration\TestCase as BaseTestCase;
use WPLaunchpadPHPUnitWPHooks\MockHooks;
summary class TestCase extends BaseTestCase
use MockHooks;
protected $config;
public operate set_up() {
dad or mum::set_up();
if ( empty( $this->config ) ) {
public operate tear_down()
public operate getPrefix(): string
return 'my_prefix';
public operate getCurrentTest(): string
return $this->getName();
public operate configTestData() {
if ( empty( $this->config ) ) {
return isset( $this->config['test_data'] )
? $this->config['test_data']
: $this->config;
protected operate loadTestDataConfig() {
$obj = new ReflectionObject( $this );
$filename = $obj->getFileName();
$this->config = $this->getTestData( dirname( $filename ), basename( $filename, '.php' ) );

As soon as this code is added then you’re free to create your fixture contained in the Fixtures folder and use them inside your exams.

Now that your surroundings for integration exams is setup it’s now time to put in writing your first integration check.

The becoming approach to run laravel queue employee in manufacturing?

Queues are primarily essentially the most useful factor in laravel after we’re coping with jobs which take longer time to complete on account of no individual must attend.
    if ($checkCurrentRunnigGame) 
return once more()->with('error', 'Recreation is already working.');

dispatch(new RunGameJob)->onQueue(‘default’);

return redirect()->to(‘dashboard’)
->with(‘success’, ‘Recreation start effectively.’);

As an illustration, the job “RunGameJob” takes e.g. 2 minutes so no individual wants their browser to attend for 2 minutes everybody wants 250ms and why not? So we use queues proper right here which take care of the roles throughout the background and later and the best way lots later? That’s an fascinating question. I will reply this nevertheless first, we see how we run queue worker.

php artisan queue:work

This command runs the queue worker and the queue worker instantly checks for any jobs throughout the jobs desk and runs these jobs.

queue worker start command

Suppose you run this throughout the terminal and in the intervening time there usually are not any jobs throughout the jobs desk so the queue worker sits and waits for the job. This works high-quality until we shut the terminal on account of in manufacturing we’re capable of’t sit for our complete life opening that terminal. Now we’ve got completely different points to do. There are two choices to resolve this downside.

  1. Cron Job
  2. Supervisor

First, we’re going to focus on regarding the cron job. This function runs that queue worker command after some time. It’s as a lot as you the best way lots time you want to wait your client to get data. As an illustration, if the admin begins the game “RunGameJob” and likewise you want to run that job instantly with none delay.


It’ll run the queue worker every minute this method is good nevertheless one drawback is concurrency Factors: If the queue worker is already processing jobs when the scheduled command is executed as soon as extra, it might finish in concurrency factors. A variety of instances of the queue worker may be making an attempt to course of the similar job concurrently, leading to shocking behaviour or errors.

So there could also be one different resolution to take care of this case which is supervisor. The supervisor is an working system issue, not a laravel issue. So take observe now we’re using an working system to resolve our downside. Let’s rephrase our requirement in straightforward phrases sooner than leaping in.

We want that queue worker to run and if it stops then restart it.

To place in Supervisor in your server, you probably can take advantage of two methods:

1. Benefit from the terminal immediately on the web server.
2. Make use of SSH to entry and arrange Supervisor.

sudo apt-get arrange supervisor

It’ll arrange the supervisor in your server.

Subsequent, generate a file named laravel-worker.conf contained in the /and so forth/supervisor/conf.d itemizing. It’s best to remain to this convention when naming directories and knowledge, nevertheless you probably can change them if wished.

Content material materials to write down down throughout the file are:


command=php //pathto your endeavor// /artisan queue:work


client= // username in keeping with you probably root//


The supplied content material materials have to be written into the laravel-worker.conf file, save, after which execute the following directions:

sudo supervisorctl reread

sudo supervisorctl exchange

sudo supervisorctl start “laravel-worker:*”


Be at liberty to proceed. Nonetheless, whenever you encounter any exceptions, on account of there are on a regular basis exceptions. One such exception might very properly be “laravel-worker: ERROR (no such group).”

It’ll occur in case your supervisor unable to detect your “laravel-worker.conf” file. To unravel this downside add the beneath code to supervisord.conf file which is located in /and so forth itemizing almost certainly.

data = supervisor/conf.d/*.conf

Enjoy and keep coding ❤️

Evaluating Binary Timber for Equality in PHP: An Elegant Technique

Binary timber are elementary information constructions in laptop science, typically used to signify hierarchical relationships between components. Figuring out whether or not two binary timber are equivalent, i.e., they’ve the identical construction and similar node values, is a crucial job in numerous purposes. On this Medium put up, we’ll discover a PHP resolution that elegantly compares two binary timber for equality.


Given the roots of two binary timber p and q, write a perform to test if they’re the identical or not.

Two binary timber are thought of the identical if they’re structurally equivalent, and the nodes have the identical worth.

Instance 1:

Enter: p = [1,2,3], q = [1,2,3]
Output: true

Instance 2:

Enter: p = [1,2], q = [1,null,2]
Output: false

Exploring the Code

Let’s delve into the PHP class Resolution and its methodology isSameTree($p, $q):

class Resolution {
* @param TreeNode $p
* @param TreeNode $q
* @return Boolean
perform isSameTree($p, $q) $p->val != $q->val) return false;
return ($this->isSameTree($p->left, $q->left) &&
$this->isSameTree($p->proper, $q->proper));

How It Works

  1. Base Circumstances:
    – If each timber are empty (i.e., each p and q are null), they’re equivalent, so the perform returns true.
    – If one of many timber is empty whereas the opposite shouldn’t be, or if the values of the corresponding nodes are totally different, the timber usually are not equivalent, and the perform returns false.
  2. Recursive Comparability:
    – If the bottom instances usually are not met, the perform recursively compares the left and proper subtrees of each timber.
    – If all corresponding nodes have the identical values and their subtrees are equivalent, the perform returns true. In any other case, it returns false.

Time and Area Complexity

Time Complexity:

  • Within the worst-case situation, the place each timber are utterly unbalanced and have n nodes every, the time complexity is O(n). It’s because the perform traverses every node of each timber as soon as.

Area Complexity:

  • The house complexity is O(h), the place is the peak of the binary timber. It’s because the recursive calls devour house on the decision stack, and the utmost depth of the decision stack is set by the peak of the timber.
  • Within the worst-case situation, the place the timber are utterly unbalanced and have n nodes every, the peak ℎ may be O(n). Nevertheless, in balanced timber, the peak is usually O(logn).


The offered PHP resolution elegantly compares two binary timber for equality utilizing a recursive strategy.
