Just had a question out of curiosity...
I am trying to explode my URL into an array like:
but wasn't working and my MySQL query was failing because no results were picking up.
I changed the code to:
array_pop(explode(" ", $_GET['id']))
and seemed to work fine...does PHP treat "+" as a blank space when using GET? And if so, why? Does it just recognize the plus sign as a normal URL parameter "joiner" and flush it out when you use GET?
