About the PHP (coding): object-oriented programming test

PHP is a popular general-purpose scripting language that is geared towards web development. PHP is fast, flexible, and pragmatic, and can power both simple static websites and complex, dynamic professional-grade web applications.

This PHP test assesses candidates' PHP skills and their familiarity with the language's unique features. It is geared towards mid-level developers and is a great initial screening test that allows you to effectively vet candidates based on object-oriented programming skills.

This coding test presents a real-life scenario to your candidates. They have 30 minutes to implement a piece of code that meets the given requirements. Candidates can run the code against a selected number of test cases to see if they are on track. After submission, the code is automatically scored based on another set of test cases that also covers exceptions or corner cases. You can play back in the coding editor to review how the code was created.

We recommend using this coding test in combination with one of our cognitive ability tests.

Any tool can have functions—bells and whistles. Not every tool comes armed with staff passionate about making the user experience positive.

The TestGorilla team only offers useful insights to user challenges, they engage in conversation.

For instance, I recently asked a question about a Python test I intended to implement. Instead of receiving “oh, that test would work perfectly for your solution,” or, “at this time we’re thinking about implementing a solution that may or may not…” I received a direct and straightforward answer with additional thoughts to help shape the solution.

I hope that TestGorilla realizes the value proposition in their work is not only the platform but the type of support that’s provided.

For a bit of context—I am a diversity recruiter trying to create a platform that removes bias from the hiring process and encourages the discovery of new and unseen talent.

Why a PHP Coding test is important

When hiring software developers for your company, you can’t simply rely on their resumes and credentials. You need to understand if your candidates have the skills they stated in their resumes by checking their abilities. An easy way to do this is by giving candidates a PHP coding test to gain insight into their skill levels.

One of the ways to test PHP coding skills is by giving your candidate a PHP (Coding): Object-Oriented Programming test. The test itself evaluates candidates’ skills by analyzing their use of PHP-specific functions. The test measures functions such as:

sort() explode() array_map()

This test might not be the best one to give to an applicant for an entry-level position, since it requires extensive knowledge of PHP. Instead, this test is best if you want to assess and hire mid-level PHP developers.

The PHP coding test is best used at the beginning of the hiring process, during the pre-screening phase. That’s because the test gives everyone the same opportunity: if candidates perform well, they will progress to the next stage, and if they don’t, they will have to improve their skills and try again the next time.

How you can use the test in the workplace

You can also use the PHP coding test in your workplace. For example, you can test your entry-level and junior programmers to see how they’re progressing in their roles and if they’re improving their skills.

One more thing you can do with this test is give it to employees who want to switch teams within the company. Some staff who wish to change their career paths and trajectories may like to try out coding and software teams. So you can use this test to see if they have the necessary skills to join your software development team.

Benefits of using a PHP coding test

There are many benefits of using the PHP coding test in your hiring process:

Candidates are assessed only on their skills. With a pre-employment skills test, everyone gets an opportunity to prove their worth. This way, your candidates are distinguished by their abilities, instead of multiple types of hiring bias.

The test is a scalable solution to a perennial problem. On average, recruiters look at each resume for only six seconds, so candidates aren’t being fairly assessed. And when you consider that many positions attract hundreds of applications, you understand that there’s no way every applicant can be treated objectively. That’s why tests provide a fair and scalable option. With a test, it doesn’t matter if you have 50 or 500 applicants; it’s still distributed with a single click.

The right candidate

The right candidate will score high on your PHP coding test and have experience working with multiple PHP coding frameworks. The most popular frameworks include:

Laravel Zend, also known as Laminas Project CodeIgniter Slim Symfony Phalcon FuelPHP PHPixie CakePHP Yii Fat-Free Framework

What happens when your candidate doesn’t have PHP coding skills

When hiring developers, you need to ensure that they have the necessary skills to do the job they’re applying for. A company that doesn’t recruit using pre-employment coding tests may run into a situation where a new hire isn’t well-versed in the required programming languages. It could result in mistakes being made on the job.

This means that the hiring process wasn’t successful, that the person who was hired can’t fulfill the job’s requirements, and that the organization will have to go through the recruitment process again to find a more suitable candidate.

To prevent this, the hiring manager should give all candidates a pre-employment test. The test will provide the HR team with insights into the best-qualified candidates, through objective, bias-free, and quantifiable results.

PHP developer skills

Candidates will need to have the required skill set if they want to perform well during the recruitment process and get hired as a PHP developer:

Understand PHP best practices and design patterns Know their way around Composer, PSR, and PHPUnit Be a problem-solver Have good communication skills Have an impeccable work ethic Be willing to learn and expand on their PHP working knowledge Learn how to adapt to a new working environment, peers, managers, and situations

How can a PHP coding test help recruiters hire?

Technical recruiting is one of the more difficult tasks for a hiring manager or recruiter, because it requires extensive knowledge of the industry and an understanding of the intricacies of the position.

When it comes to PHP coding, the recruiter will need to understand what a good, clean code is, recognize the limitations and possibilities inside different PHP frameworks, and discern which programmers are qualified to do the job they’re applying for.

All of this puts immense pressure on recruiters, but one way to alleviate that pressure is to give candidates pre-employment tests. When it comes to PHP programmers, you, as a hiring manager, can get a headstart in the screening process by asking candidates to take a pre-employment coding test. The results of TestGorilla’s tests are objective, bias-free, and quantifiable, helping any hiring manager to make better and swifter hiring decisions.

In summary

A PHP coding test should be a part of your pre-employment screening process, to help you see which candidates are qualified to do the advertised job. With a coding test, you can easily verify the claims candidates make in their resumes.

All of this will make the hiring manager’s job easier, since they will receive objective results for all of the candidates. This will help them to choose the right applicants to interview, safe in the knowledge that these candidates possess the required skills.

And with a coding test, it doesn’t matter how many applications you receive during the hiring process. The PHP coding test is a scalable option, so whether you have 50, 100, or 500 applicants for your open position, it’s just as easy to distribute the test to them all.
