I am not sure but here is link for info about it .

query string is the $_GET information so "www.google.ca/?op=alsjdf&div=asflj" the query string would contain "?op=alsjdf&div=asflj"

 

that function takes all the $_POST information, and turns it into a string that can be transfered via $_GET... :-)
