PHP interview questions: environment, background, and usage

These are general questions that you might get about the language and what it’s used for. This is information that anyone who is a little familiar with PHP as a concept should know.

1. What does PHP stand for?

PHP stands for PHP Hypertext Preprocessor. This is a recursive acronym, somewhat like GNU (Gnu’s Not Unix). It’s important to understand this because it also defines the language. PHP is not a compiled language; it’s an interpreted language — it’s a “hypertext preprocessor.” It processes a website before the website gets processed in HTML, CSS, and JavaScript. This adds another layer onto the interpretation of the site.

2. What type of language is PHP?

PHP is an open-source scripting language. Specifically, it is not a compiled language but an interpreted language. PHP is closer to Perl and CGI than it is to C or Java. This is important to know because it changes the framework of how PHP is used. PHP is not compiled as an executable, but rather the script gets executed as it’s read, much like JavaScript.
