This question is an opportunity to show your knowledge of a basic programming concept. Variables are used in many different programming languages, so you can use this answer to show that you understand how they work and how they apply to PHP.
Answer Example: "A variable is a container for data that can change over time. It’s similar to a cupboard where you store items, except that it has a name so you can remember what’s inside. In PHP, I use variables to store information like numbers, strings and arrays. For example, if I wanted to keep track of how many times a user has clicked on a button, I would create a variable called $counter and set its value to zero. Every time the user clicks the button, I would add one to $counter’s value."
Debugging is a common task for PHP developers. The interviewer wants to know how you approach debugging errors in your code and whether you have any previous experience doing so.
Answer Example: "I recently had to debug an error in my code. The problem was that the website wasn’t displaying properly, but after looking at the code I realized that there were multiple issues. First, there was a typo in one of the functions, which caused another function to not work properly. After fixing the typo, I realized that another function was also missing a closing bracket. Once I fixed both of these issues, the website displayed properly."
