Single quotes versus double quotes

Use single quotes around strings whenever possible as it makes less work for the PHP parser. Exceptions where you do need to use double quotes: when outputting variables, using single quotes and escape characters (eg - \n).

Very Helpful. I am just starting out and couldn\'t understand why the variable values couldn\'t be displayed and then I realised that I was using single quotes instead of double.
