Should I use a loop to do this? Any suggestions? Please email >me at corky6921@yahoo.com with suggestions. > >Thanks, >Erica > I think, begining from some php >4, preg_replace allows to do this, Otherwise, you could use preg_match to find first match then strpos() to find it position, and, finaly substr() with concatenation to your replacement. This loong way was the first, that came to my mind for cases, where regexp realy needed. (If they are not needed, str_replace() would work faster/simlier, you know o'cos:). Note: for some strings I experience hangup, especially w/ereg_replace, but also, for long ones, w/preg0. Regards. Leonid.
