About the test

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.

Sample public questions

You're maintaining the PHP back-end of a Tree Planting website.

The registerForEvent function is called by the server when interested people fill a form to register for a tree planting event.

The register function it calls performs the registration logic.

Consider the code for the registerForEvent function:

function registerForEvent($name, $seedBagsNeeded)
{
    $sanitizedName = filter_var($name, FILTER_SANITIZE_SPECIAL_CHARS);
    $filteredBagsNeeded = filter_var($seedBagsNeeded, FILTER_VALIDATE_INT);
    register($sanitizedName, $filteredBagsNeeded);
}

What is correct about the filtering and sanitization done in the code above?

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"]].
