The flag remains greedy and doesn't replace the first value="ems" is replaces the 2nd one(technically it replaces all of it but i thought it would be easier to explain this way.) See source Reproduce code: --------------- $string='/(name="One".*value="ems")/Usi'; echo $string."<br>"; $content = 'One:<select name="One" id="One"> <option value="">&nbsp;</option> <option value="picas">picas</option> <option value="ems">ems</option> <option value="exs">exs</option> <option value="%">%</option> </select> Two<select name="Two" id="Two"> <option value="">&nbsp;</option> <option value="picas">picas</option> <option value="ems">ems</option> <option value="exs">exs</option> <option value="%">%</option> </select>'; $result = preg_match($string, $content); $replace ='\1 selected'; $um = preg_replace($string,$replace,$content); echo "matches: ".$result."<br>".$um; Expected result: ---------------- I expected value="ems" in the "one" select to become value="ems" selected. Actual result: -------------- value="ems" in the "two" select became value="ems" selected. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28690&edit=1
