   • CMS Experience: WordPress, Drupal, or custom CMS development
   • Security Practices: SQL injection prevention, XSS mitigation

1. Top Skills to Assess When Hiring a PHP Developer

   PHP can never be used as a stand-alone language. It works in tandem with other languages on the client side to form a functioning website.

   If you’re looking for full-stack PHP developers, test their grasp over Javascript, CSS, and HTML. This will allow developers to build both a functional and user-friendly website.

   As with any web developer, hire PHP programmers who are good at problem-solving. Quick and critical thinking will be vital to delivering projects on time.

   Hire top remote PHP developers who have experience working with Ajax, jQuery, and MySQL. Being comfortable with databases like MySQL implies that the developer has well-rounded skills. This will certainly be an asset to your team.

   Lastly, the PHP developer has to have good communication skills. This is especially necessary if you’re looking for remote PHP developers for your team.

   On top of these skills, for hiring a PHP developer you should also test their technical knowledge. Here are the 5 top technical questions to ask them.

2. Top 5 Technical Interview Questions when Hiring a PHP Developer

   Here are the top 5 technical interview questions you should ask to the candidate:

   What are Composer and Packagist in PHP?

   Composer is a dependency manager for PHP that allows you to declare and manage libraries on which your project depends. Packagist is the main repository for Composer packages, where developers can publish their PHP packages.

   Unlike the obsolete PEAR system, Composer offers project-level dependency management, version constraints, and automatic dependency resolution.

   A PHP developer should be familiar with Composer commands like composer require and composer install and understand how to define dependencies in the composer.json file. This knowledge is essential for efficient modern PHP development.

   What is the OOPs concept, and what are its Principles in PHP?

   The following answer would be ideal:

   OOP is a programming approach where there’s an emphasis on data and its associated functions. With the rising importance of data, OOP is becoming an essential concept. In PHP, OOPs help to make the code easier to maintain and modify. PHP has six OOP concepts – Class, Objects, Inheritance, Interface, Abstraction, and Magic Methods.

   What is a closure in PHP? Why is it used?

   Also known as an anonymous function, a closure is a function that can be created without a specific name. Closure gives you access to an outer function’s limit from an inner function.

   The closure function was introduced in PHP 5.3 and is most widely used for the callback function. It is especially useful when accessing higher-order functions.

   What are the differences between $message and $$message?

   Expect the following answer:

   $message is a regular variable whereas $$message is a reference variable. $message stores a fixed data value and has a fixed name. However, the $$message stores data about the variable. So the $$message changes when the variable does.

   What are the rules for naming variables in PHP?

   These are 5 rules for naming variables in PHP.

   • All variables start with the ‘$’ symbol followed by the name.
   • The variable name must start with the ‘_’ symbol or a letter
   • The name cannot have spaces
   • Variable names can only contain alphanumeric values or an underscore. No other characters may be used.
   • Variable names are case sensitive

   Since variables are what store data in a program, this is a fundamental concept you should look for when hiring a dedicated PHP programmer.

   What are static analysis tools like PHPStan and Psalm? How do they improve code quality?

   A good answer would include:

   Static analysis tools like PHPStan and Psalm analyze PHP code without executing it, identifying potential bugs, type inconsistencies, and other issues. PHPStan focuses on finding errors in code by analyzing type hints and docblocks, while Psalm emphasizes type safety and offers additional features like taint analysis for security vulnerabilities.

   These tools help improve code quality by:

   • Catching bugs before they reach production
   • Enforcing consistent coding standards
   • Identifying potential security vulnerabilities
   • Reducing technical debt through early detection of issues
   • Supporting gradual typing in PHP projects

   A developer should be able to explain how to integrate these tools into CI/CD pipelines and understand the concept of rule levels or strictness settings in both tools.

   How can you optimize a slow Laravel query using eager loading?

   Eager loading reduces database calls by fetching related data upfront. Use methods like with() to load relationships in one query instead of multiple, withCount() to count related records efficiently, and database indexing on foreign keys. Avoid nested loops that trigger unnecessary queries.

   PHP 8.3’s #[\SensitiveParameter] attribute

   This attribute hides sensitive data (like passwords) in error logs and stack traces by replacing values with placeholders. It prevents accidental exposure of confidential information during debugging or crashes.

   Debug a Dockerized PHP API failing on Kubernetes

   Check pod health and logs for errors, verify container dependencies (PHP extensions, configs), test network connections between services, enable PHP error logging, and ensure resources (CPU/memory) are allocated properly to avoid crashes.

   But beyond technical PHP prowess, you should hire the best PHP web developers who also have good problem-solving skills. Coding doesn't have to be their forte. But if they’re able to showcase a presence of mind, you shouldn’t discount that PHP web developer.

3. Top 5 Exploratory Interview Questions when Hiring a PHP Developer

   A key factor to understand here is that there are no right or wrong answers. These questions are asked merely to understand what the PHP developer is like as a person.

   What was the most challenging problem you faced when developing a PHP code, and how did you solve it?

   This is a roundabout way of asking what their least favorite part of PHP web development is. By this, you can gauge what the candidate believes is their weakness.

   The answer to how they overcame the challenge will reveal to you their way of working. See what resource they consulted for help, or if they gave up and passed on the challenge to someone else.

   What is the largest application you’ve ever worked on? Explain some of the key concepts of it.

   The answer to this question will tell you the extent of skill the potential PHP web developer hire has. The concepts of the application will show you the candidate’s strengths and weaknesses.

   And the confidence they show in the answer will also reveal how big of a part the candidate had in developing that program.

   Is there a programming language that you wish you’d learned?

   If they say yes, your follow-up question should be if they’ve made any effort to learn the language. If they have started learning other programming languages, you can tell that the candidate is adaptable and resourceful.

   If they say no, then that may reveal that the potential hire has no interest besides PHP. This, in itself, would be a problem, as just knowing PHP isn’t sufficient.

   Is PHP web development your long-term goal?

   Their answer to this question will tell you what the candidate’s long-term goals are. It’s okay if it’s just in PHP development. But you should follow up by asking how they plan to improve their skills in PHP web development.

   You don’t want to hire PHP developers who indicate that they’re going to be stagnant employees.

   Apart from PHP, what would you say you’re best at?

   The answer to this doesn’t have to be about web development. But if they do talk about other programming languages they’re good at, then you can gauge their technical skills beyond PHP.

   But if they talk about extra-curricular activities, then you’ll be able to tell what the candidate is like outside of the office. This information would open up information about the temperament of the candidate.

   These questions will help you get a well-rounded opinion about the candidate. Go through this list to hire top PHP developers.
