Something I wasted a lot of time puzzling over till I stumbled across the reason just a moment ago!
PHP is an ''interpreted language'' (like Perl) and not a ''compiled'' one (like [[Java]] or [[C]]).

==String handling==
==Strings==
Strings can be placed in single quotes or double quotes; this differs from Java, where single quotes are used only to enclose one single character rather than a string.
Important note:
* single quoted strings don't recognize special character codes like \n [http://www.sitepoint.com/article/advanced-email-php/3/]
===Concatenation ===
The [[string concatenation]] operator is the period (or full stop). This is a big difference from most other languages, which use a plus sign or ampersand.
