About the test

The PHP online test assesses knowledge of programming in the PHP language through a series of live coding questions.

The assessment includes work-sample tasks such as:

  • Serializing to/from JSON to handle web requests.
  • Using OOP principles in PHP.
  • Working with associative arrays and using common built-in functions.

A good PHP developer needs a solid understanding of the PHP programming language and its specifics, OOP principles, and the ability to take advantage of its rich set of built-in functions.

Validation

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?

Associative Arrays

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"]].

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
