The string is "<td>charge</td><td>100</td>". I want and array( "charge"=>100). I am using this regular expression, '/<td>([^<]+)<\/td><td>(?P<\1>\d+)<\/td>/'. But its not working.. I get this error., PHP Warning: preg_match(): Compilation failed: syntax error after (?P at offset 25 in E:\src\php\WebEngine\- on line 4 any idea?

$string = '<td>charge</td><td>100</td>'; preg_match('|<td>(.*)</td><td>(\d+)</td>|', $string , $out); print_r( $out );
