In compiled languages, you can often catch errors at compile time, something that does not happen in interpreted languages.īut on the other hand, an interpreted language has more flexibility.įun fact: PHP is written internally in C, a compiled and statically typed language. Compared to strongly typed languages like Swift, Go, C or Java, you don’t need to declare the types of your variables.īeing interpreted and loosely/dynamically typed will make bugs harder to find before they happen at runtime. (These also happen to be compiled – the two characteristics often go hand in hand.)

#PHP LANGUAGE PROGRAMMING CODE#

The types of variables are checked at runtime, rather than before the code is executed as happens for statically typed languages. You tell the interpreter to run the program. The PHP interpreter is responsible for interpreting the instructions written in a PHP program when it’s executed. Those languages are compiled and the compiler generates an executable program that you then run. If you’ve used compiled languages like C or Go or Swift, the main difference is that you don’t need to compile a PHP program before you run it. PHP is often called a “scripting language” and it’s an interpreted language. For example interpreted/compiled, strongly/loosely typed, dynamically/statically typed. Programming languages are divided into groups depending on their characteristics. Or you can use it as a Web Application engine that creates HTML pages dynamically and sends them to the browser.ĭid you know Facebook is powered by PHP? Ever heard of Wikipedia? Slack? Etsy?
