Single Quotes vs. Double Quotes

  • Use single quotes to refer to an index between brackets of an array (ex: $fooname? and not $foo[name] or $fooname?)
  • Use single quotes instead of double quotes as much as possible because it's faster to parse.
    • You must use " with the gettext() stuff [eg. _("Translatable String")]

Line Spacing

  • No tabs, only spaces
  • Indent using 2 spaces

SVN Info

  • $Id$ Tag inside the heading comment
    • Example: 
         /* $Id$ */

Variable Settings

  • Paranoid log level safe code.
    • Initialize variables. (just $a=0 is initialization)
    • Use isset($var)

Echoing HTML

  • PHP code should not echo anything.
  • PHP code should strictly use templates to generate output.

Code Format

  • Inside if, for and while structures, space and {} are mandatory following this example: 
     foo (whatever) {
    do something important;
 }
