The problem you ran into is the last "=" was being matched rather than the first due because "=" is matched by (.*). Also, you can accomplish the same thing, more accurately, with one expression by adding a middle atom. This new middle atom catches both spaces, no spaces and tabs in any combination. if ( ereg("^([[:alnum:]_]*)([[:space:]]*=[[:space:]]*)(.*)$",
 $lines[$i], $regs) ) {
you also could do something like
 } elseif (ereg("^([^=]*) = (.*)", $lines[$i], $regs)
 || ereg("^([^=]*)=(.*)", $lines[$i], $regs)) {
to match only the first '=' in the line...

Or try: elseif (preg_match("'^(.*?)[\s]*=[\s]*(.*)'", $lines[$i], $regs)) { Greetz, Wico
