RE: [PHP] Reg Exp Help

Hmmm. I am searching thru a flat file that has been loaded into an array ($file_array[$i]). As each iteration of the array is loaded (each row of the flat file) , I was trying to search for this unique combination. The $password is not unique. And $int_id is not unique enough (e.g., "a", "b", "c", etc.) to be searched for on its own. However, $password and $int_id joined together is unique. Also, the $password and $int_id are in a fixed position in each header row, however, not every row in the flat file is a header row (no...I didn't create a flat file in this way!). I am confident the correct regular expression would resolve this. I will keep thinking about substr() and trim(), but I don't see how to use those to resolve this issue.
