Note Submitter: buracco@yahoo.com ---- Say you have a pattern with 3 groups and want to replace 2nd. i.e. (\w+=")(\d+)(") preg_replace($pattern, "\$1$replacement\$3" ,$subject) Works fine unless $replacement starts with a number. What to do then? p.s. When matching, ...If the pattern continues with a digit character, then some delimiter must be used to terminate the back reference. If the PCRE_EXTENDED option is set, this can be whitespace. Otherwise an empty comment can be used.comment can be used...
