What is PHP?
PHP stands for Hypertext Preprocessor. It is a popular scripting language primarily used for web development. PHP is especially known for its ability to create dynamic content on websites, making it an essential tool for developers. Unlike HTML, which is a static markup language, PHP allows for more interactive and engaging websites. Since the launch of PHP in 1995, it has grown significantly and remains a top choice for many developers in 2026.
