Premium questions with real-world problems
The PHP online test assesses candidates' knowledge of programming in PHP language and their ability to leverage commonly used built-in functions.
It's an ideal test for pre-employment screening. A good PHP developer needs to be able not only to solve problems using PHP as the programming language but also recognize when to take advantage of its rich set of built-in functions.
This test requires candidates to be able to solve coding problems in PHP and find and fix bugs in PHP programs.

Free Sample Questions for PHP Test
Our sample questions are free for companies to use on a trial plan. See more about our premium questions for paid plans below.
File Owners
Implement a groupByOwners function that:
- Accepts an associative array containing the file owner name for each file name.
- Returns an associative array containing an array of file names for each owner name, in any order.
For example, for associative array ["Input.txt" => "Randy", "Code.py" => "Stan", "Output.txt" => "Randy"] the groupByOwners function should return ["Randy" => ["Input.txt", "Output.txt"], "Stan" => ["Code.py"]].
Merge Names
Implement the unique_names function. When passed two arrays of names, it will return an array containing the names that appear in either or both arrays. The returned array should have no duplicates.
For example, calling unique_names(['Ava', 'Emma', 'Olivia'], ['Olivia', 'Sophia', 'Emma']) should return ['Emma', 'Olivia', 'Ava', 'Sophia'] in any order.
Quadratic Equation
Implement the function findRoots to find the roots of the quadratic equation: ax2 + bx + c = 0. The function should return an array containing both roots in any order. If the equation has only one solution, the function should return that solution as both elements of the array. The equation will always have at least one solution.
The roots of the quadratic equation can be found with the following formula: 
For example, findRoots(2, 10, 8) should return [-1, -4] or [-4, -1] as the roots of the equation 2x2 + 10x + 8 = 0 are -1 and -4.

Pass/fail grouping
Our tests are designed to put candidates into either the pass group or the fail group so you can find the best candidates faster.
Full customization
We have pre-built tests and questions, but you can customize them however you like. Change the pass/fail scores, time requirements, and more.
Cheating protection
Use tests that solve real-world problems, with no answers that can be easily found online. Because we test performance and skills (not information), we allow the use of online resources, just like in real life. Copy/paste prevention and online proctoring via webcam prevent cheating.
Candidate reporting
Get an overview into the percentage of passes and fails. Then dive deeper into the results of your top candidates to select who goes onto the next phase of hiring.
