SciTE is a nice free multiplatform editor, mostly for coders. It's a bit tricky to configure though, so here are some hints. 1/ PHP-files as source When you click 'Open' and the file open dialog is shown there is a filter activated to only show source-files. This filter doesn't include PHP files, which is bad for me :) The solution: Start with making the global configuration file writable: sudo chmod 777 /usr/share/scite/SciTEGlobal.properties Next, open the file in SciTE by choosing Options/Open Global Options File. Find the filter settings: # The open.filter setting is only used on Windows where the file selector has a menu of filters to apply # to the types of files seen when opening. # There is a limit (possibly 256 characters) to the length of a filter, # so not all source extensions can be in this setting. source.files=*.asm;*.c;*.cc;*.cpp;*.cxx;*.cs;*.h;*.hh;*.hxx;*.hpp;\ *.idl;*.odl;*.rc;*.rc2;*.dlg;*.def;\ *.vb;*.vbs;*.bas;*.frm;*.cls;*.ctl;\ *.java;*.js;*.py;*.pl;*.rb;*.cgi;*.lua;*.conf;\ make*;*.mak;\ *.properties;*.html;*.xml;*.iface;*.bat;*.e After '*.e' we add ';*.php', saves the file and we're done. Another idea is to also add CSS, then the last line looks like this: *.properties;*.html;*.xml;*.iface;*.bat;*.e;*.php;*.css
