What is the full form of PHP?

The answer

The full form of PHP is PHP: Hypertext Preprocessor. It is a recursive acronym, which means the first letter stands for the name itself, and the PHP manual describes it in exactly this way. The older meaning was Personal Home Page, from the early tools that Rasmus Lerdorf made for his own website in 1994. In an exam or interview, give the current expansion first, then mention that it is recursive and add the original meaning. See also the guide PHP Full Form: Meaning, Origin and Why It Matters.
