Note Submitter: river@dialling.spamfree.info ---- The callback function is called once for each match, and should return the replacement value for that match. The array passed to the callback function will only have a single element unless you have used ( ) in the match pattern. Example: find keywords introduced by `` and replace with values from table $val $val[bird]='cormorant'; $val[bird2]='shag'; $val[nest]='paper bag'; $sample = 'The common `bird or bird2, lays its eggs in a `nest'; $result = preg_replace_callback('/``(\w+)/', lookup, $sample); echo $sample,"\n<hr>\n",$result; function lookup($items) { global $val; return $val[$items[1]]; #first ( ) in pattern }
