I experienced it myself, quite a big difference!
Try to avoid split if you don't need the reg. expr in delimiter/separator
Don't know if any other functions in php have the pair like this (do the same thing, but different in purpose or performance)
Oh, one example in another thread: echo/printf/print
str_replace vs. ereg
huge performance difference if you don't need the specific properties of ereg
Yes, thank you so much!
Bring my scripts to the next level :)
Also check out the comparisons at http://www.php.net
Are there any more functions related to this?
