Share The PHP array :? Pid = 2 ???? [1]? =>? Action = save ???? [2]? =>? 9 = ???? [3]? =>? 10 = ??... 'Data-pics = ''>
------ Solution --------------------

$a = array(
  'pid=2',
  'action=save',
  '9=a',
  '10=a',
  '14=a',
  '20=a',
  '15=a',
  '15=b',
  '21=a',
  '21=b',
  '16=c',
  '16=d',
  '19=c',
  '19=d',
  '17=we',
  '22=keywork',
  '18=you',
  '23=thanks',
);
foreach($a as $v) list($b[$v][],$v) = array_reverse(explode('=', $v));
array_walk($b, create_function('&$v,$k', '$v="$k=".join("",$v);'));
print_r(array_values($b));
