A few changes here. First of all, as per extensive discussion on the list, the functions are now prefixed with "preg" instead of "pcre". Secondly, global matching is now possible using preg_match_all. Please, give suggestions on a better name if this one doesn't sit well with you. Possible names are preg_global_match and preg_gmatch. preg_match_all takes 4 arguments: a regex pattern, a subject string, the array for capturing subpatterns, and a parameter that tells how the results in the subpatterns array are arranged. Basically, preg_match_all will go through the subject string and try to capture all the matches that it finds, not just the first one like preg_match. 4th parameter can be PREG_PATTERN_ORDER (default) or PREG_SET_ORDER. Example: preg_match_all("|</?([^>]+)>|", "<div align=left>a test</div>", $out, PREG_PATTERN_ORDER); This returns results so that $out[0] is an array of full pattern matches, $out[1] is an array of first captured subpattern matches, and so on. $out[0] -> ("<div align=left>", "</div>") $out[1] -> ("div align=left", "div") Example: preg_match_all("|</?([^>]+)>|", "<div align=left>a test</div>", $out, PREG_SET_ORDER); This returns results so that $out[0] is an array of first full pattern match and subpatterns, $out[1] is an array of second full pattern match and subpatterns. $out[0] -> ("<div align=left>", "div align=left") $out[1] -> ("</div>", "div") If anyone has a better name for these PREG_ constants and also which one should be the default, I'd like to hear it.
