GeSHi

GeSHi is a powerful software that offers an effective solution for syntax highlighting in PHP. It is a generic syntax highlighter that takes any source code and highlights it in XHTML and CSS. The software started as an idea to create a highlighting feature for the phpBB forum system, but it has been generalised to this project. Its primary aim is to provide a simple but robust highlighting class with a wide range of popular languages supported.

One of the significant benefits of GeSHi is that it is easy to add a new language for highlighting. It is highly customisable, with a vast number of output formats available. The software currently supports over 30 languages, including Java, C, PHP, CSS, SQL, HTML, Pascal, C++, XML, ASP, and ASM. GeSHi offers a high-speed highlighting process through its customisable features. It finds a balance between the amount of highlighting done and the speed in which it is done.

GeSHi offers support for PHP5 and Windows, and it can be used to highlight code on ASP pages. Numerous blogs, wikis, and forums use GeSHi, including Dokuwiki, Mambo, phpBB, and WikkaWiki. Overall, GeSHi is an excellent software that developers can rely on for effective syntax highlighting in PHP. Its simplicity, flexibility, and speed make it stand out from other syntax highlighting software.
