Reproduce code: --------------- <?php $search = "qx\0qqqqqqqqqq"; $subject = "qx\0xxxxxxxxxx"; $replace = "any text"; $result = str_replace ( $search, $replace, $subject ); echo $search . "\n" . $replace . "\n" . $subject . "\n" . $result . "\n"; ?> Expected result: ---------------- qx qqqqqqqqqq any text qx xxxxxxxxxx qx xxxxxxxxxx Actual result: -------------- qx qqqqqqqqqq any text qx xxxxxxxxxx any text ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=39621&edit=1
