## About our PHP coding tests

We provide PHP code exams for your team that are realistic and useful, giving a precise assessment of candidates’ PHP skills. Even if you don’t have a technical background, you can develop PHP code tests in under a minute using tools like CoderPad Screen.

We have created our tests to precisely cover important ideas like object-oriented programming, data structures, algorithms, and more. Our industry specialists have carefully selected them to ensure their applicability to real-world situations and their efficacy in evaluating candidates’ talents.

There is an ability to modify the tests and add their own coding activities for hiring managers who wish to go further.

• Recommended duration: 30-80 min
• Average number of questions: 15
• Type of exercises: Multiple choice, coding exercises
• Test levels: Junior, Senior, Expert

## PHP sample questions

### Example Question 1

What is the difference between abstract classes and interfaces in PHP?

### Example Question 2

What will be the output of the code below?

``````<?php
function multiplyByTwo(\$number) {
\$number *= 2;
return \$number;
}

\$number = 5;
echo multiplyByTwo(\$number);
?>```Code language: PHP (php)```

### Example Question 3

In this exercise, you have to analyze records of temperature to find the closer to zero.

Sample temperatures. Here, -1.7 is the closer to 0.

Implement the function `closestToZero` to return the temperature closer to zero which belongs to the array `\$ts`.

• If `\$ts` is empty, return 0 (zero).
• If two numbers are as close to zero, consider the positive integer as the closer to zero (eg. if `\$ts` contains -5 and 5, return 5).

Input:

• Temperatures are always expressed with floating point numbers ranging from -273 to 5526.

## Explore Code Playback

Obtain a deeper understanding of the problem solving thought process of your developer applicants.

• Witness their proficiency in building algorithms and evaluate their approach to solving problems with them.
• Jot down feedback from different segments of the interview to discuss in subsequent interview rounds.
• Pay attention to detect and prevent any distasteful actions.

## How to test PHP skills to hire for your team?

Relying only on resumes may not accurately paint a broad picture of a PHP developer’s skills and abilities, and self-reported skills may be untrustworthy.

Here are five ways to assess PHP developers’ coding skills:

• Examine their body of work. This provides you with more information about the kinds of PHP projects they have worked on and their level of language expertise.
• Examine their GitHub account to judge the quality of their PHP code, their projects, and their participation in PHP-related projects.
• Ask about their use of Stack Overflow or PHP communities in their day-to-day development to understand their knowledge level and participation in the PHP development community.
• Employ the use of practical PHP focused programming exercises for PHP developers to allow them assess and improve their coding skills.
• Conduct PHP-focused live coding interviews in which candidates can exhibit their coding skills, problem-solving talents, and understanding of PHP fundamentals.

## How to approach initial candidate screening effectively?

Some recruiters are concerned that putting coding tests on candidates early in the interview process will intimidate potential prospects and discourage applications. However, good scenario management, such as clarifying the interview process and why it is vital, will help candidates comprehend the goal and feel at ease.

Here are some guidelines for you to ensure a positive candidate experience during early testing:

1. Job Ad: Make certain that the advertisement includes every phase and expectation of the hiring process. As a result, the candidate will not feel singled out and will be able to fully prepare for the interview. It is also a good idea to convey the time limits involved in technical interviews ahead of time.
1. Highlight Equal Opportunities and Diversity: Emphasize your company’s commitment to promote diversity and equal opportunity through the testing process. It must to be obvious that the major objective of the assessment is to fairly evaluate the candidate talents, regardless of history.
1. Concise Assessment: Choose quality over quantity by keeping the assessment brief and focused on the skills required for the job. This is to eliminate any time wasting and ensure the candidates can attempt the exercise hitch-free. Ideally, aim for a test that can be completed within an hour or less without compromising any requirements.
1. Relevance: By ensuring that the examinations only focus on the abilities that are specifically relevant to the position, redundancies can be avoided. Developers value candidates that show pragmatism by emphasizing practical abilities that have an impact on daily work.
1. Feedback and Results: Provide applicants with performance comments after the testing phases. You may improve candidates’ experiences by using a product like CoderPad Screen, which automatically creates a concise report and sends it to them. Candidates who do poorly will be able to understand why they were passed over for the following round in this way.

We had no unified approach or tool to assess technical ability. Today, CoderPad Screen enables us to test against a wide selection of languages and is continually updated.
