is there problem (performance-wise) manually parsing string follows, opposed using regular expressions or built in string replacement functions? for ($i=0;$i<strlen($string);$i++) { $thischar = $string[$i]; //do more stuff } thanks! there things done more efficient custom code regex. as long both have same o complexity , not handling humongous strings, readability , maintainability should equally or more important argument. for actual performance benchmark compare 2 solutions.
