markdown guide
 

IIRC PHP does not interpolate variables in single quotes. So the ultimate guide is:

  1. Double quotes if you "need $variables" in your string (and you don't want 'to' . 'join' . $them)
  2. Single quotes for everything else.
 
 

Well, single quotes are slightly faster than double quotes (if that matters for your script).
