J'ai créé pour mon site (forums, tutos, mp etc.) une fonction qui permet de colorer syntaxiquement les langages suivants :
- Le PHP
- Le (X)HTML
- Le SQL
- Le CSS
- Le ActionScript
Cette fonction utilise en particuliers les expressions régulières et plus précisément la fonction preg_replace();. Je pense en faire un tuto sur mon site, mais pour ceux que ça intéresse :
