&II=3&DI=10&OSI=7&RPN=3&SQ=1
What command would help me with this?
You don't need any command. Now you have in your php script which is opened by this url: $II='3' $DI='10' $OSI='7'... You can call them by their names in your script.
I input a url from a list into a variable put I want to extract the &II=this from the url in string format.
