A string inside of double quotes is always parsed for execution.  That 
means that php will look inside the string and check for any code that 
can be executed.

A string inside of single quotes is never parsed for execution.  The 
string will just be taken literally and code inside of it will not be 
executed.

$stuff = 'things';
echo "I like $stuff"; // output: I like things
echo 'I like $stuff'; // output: I like $stuff

In general you should use double quotes when you want part of a string 
to be parsed and executed.  You should use single quotes otherwise.
