Okay so i just found out that \n for new line
does not work if you are using single quotes,
it does if  you use double quotes however.

So what is the huge difference and why would
i ever not need to use double quotes?

single quotes are static strings and are compiled into the code as is... so particularly if you're using something like APC and you have a lot of strings, it's faster. If you don't need to do any processing on the string, that's the best way to go.

Double quotes processes the string, dereferencing any variables and controls (like \r\n etc) so there is more overhead if you're doing a lot of them.

In most cases, it probably doesn't matter much, although I'm always about that because it tells ME that I am doing processing a string very quickly, and I'm an efficiency nut.
