Well, should have make one long string to the $res_str variable a lot shorter. :-)
It turned out that the for() loop isn't the slow part when you mentioned about substr(). I tried out the while() loop and it is pretty much the same when the loop take over 5 minutes. So, it now seem to have to do with substr() function. Yea, I'm not sure what hte best substitute of it would be. In other branches off of this posting, someone said about using the strpos(). I'm willing to give this a try but I have problem with this because I have two "<!CDATA[[***]]>" tags in it and I want to use both, not just first one. Scott "Chris W.

Are you sure the for() loop is the slow part? 2. As someone already suggested, calculating the sizeof() outside of the loop should help a lot. Another enhancement is changing your for() to while(). (This is a small enhancement but makes a bigger difference as your iterations increase.) REGULAR for() loop construct: $iMax = 99; for($iCnt = 0; $iCnt < $iMax; $iCnt++) { } OPTIMIZED: $iMax = 99; $iCnt = -1; while(++$iCnt < $iMax) { } Like I said it's only slightly faster, but might make a difference depending on your number of iterations. 3. I think what may be slowing you down is your substr() calls. Maybe there is a substitute function that is faster? (I don't have any ideas unfortunately.) Let us know if you figure something out.
