gPHPEdit is a PHP file editor that also supports HTML/CSS. It is a dedicated tool for editing these particular file types.
One standout feature is the syntax highlighting, which extends to PHP, HTML, CSS, and even SQL (although this feature is still in beta mode). The editor also supports coding assistance, with features like dropdown function lists that recognize all PHP functions up to and including PHP 4.3.0, function parameter popups, and a class/function browser.
If you're concerned about syntax errors, don't worry - gPHPEdit has you covered with lint checking that underlines problematic lines with a red wavy line. For navigating code, you can use the incremental search (Ctrl+I) or go directly to a specific line using Ctrl+G.
GPHPEdit also offers integrated help that's context-sensitive and hyperlinked for easy navigation. Simply highlight the PHP function you're curious about and hit F1 to open the appropriate help page in a new tab. Plus, there's no warm-up time when you press F1 - pages load almost instantaneously thanks to the help system's integration with the editor.
One minor thing to note is that gPHPEdit requires the GtkHTML component, so make sure you have that installed before you start using this editor. Overall, gPHPEdit is a reliable choice for your PHP programming and editing needs.
