What the quiz covers
PHP still powers a large share of the web, including WordPress and Laravel apps, and many Indian web agencies hire for it. The 25 questions are grouped into 9 areas, shown above each question: Basics, Arrays, Web, Security, OOP, Modern PHP, Tooling, Functions, Frameworks.
A sample question explained
"Which is the safest way to run SQL with user input in PHP?" The answer is PDO prepared statements with bound parameters. Prepared statements prevent SQL injection. Concatenating user input into SQL is the classic mistake that leads to SQL injection; interviewers expect you to say 'prepared statements' straight away.
More questions you'll meet
A few of the other PHP questions in the bank:
- What's the difference between == and ===?
- How do you create an associative array?
- What does isset($x) return for a variable set to null?
- How do you start a session?
- Which function should you use to store passwords?
- What does __construct define?
- What does PHP 8's nullsafe operator ?-> do?
Study tips
- Run each snippet with php -a (interactive mode) or an online sandbox.
- Learn the security questions especially well: SQL injection, XSS and password storage come up in every PHP interview.
- Aim for at least 20 out of 25 on two separate attempts before you treat PHP as revised; one lucky score can hide gaps.
Questions and options are shuffled on each attempt, so a retake is a fresh test. The PHP questions were written by Uncodemy for practice; they aren't copied from any exam or company test.
