The PHP, MySQL and SQL online test assesses candidates' knowledge of programming in the PHP language, as well as their ability to use MySQL and SQL.

It's an ideal test for pre-employment screening. A good PHP developer, who is working exclusively on an MySQL server database layer, needs to not only solve problems using PHP, but also to write and analyze SQL queries that are used for communication with the database and to use MySQL-specific features to interface efficiently with a database. 

This online test requires candidates to solve coding problems in PHP, answer multiple-choice questions about MySQL and write SQL queries that extract, combine, and manipulate data.

Implement a groupByOwners function that:

  • 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"]].

What Others Say
TestDome user reviews on G2 Crowd
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.

Jan Opperman, Grindrod Bank

Very smooth, well supported, great for assessing candidates

Very Prompt and helpful support when needed, we were looking to work with a third party to write and set up new tests, TestDome was able to quickly set up and support a method to do this, allowing us to start testing candidates straight away.

George Offer, Guided Solutions

Easy to use and efficient for testing developers of different levels

It provides us an opportunity to set our own timing policy, to choose from variety of questions from different areas and with difficulty gradation. Also it is great that TestDome provides free of charge tests for candidates to prepare and check how online IDE works. And support is always ready to help:)

Screening Applicants: The Good, the Bad and the Ugly

Since we’re all biased and we use incorrect proxies, why not just outsource hiring to experts or recruitment agencies? After all, they’ve been screening people for many years, so they must know how to do it right?
