Search array element values similar to mysql like

I have to search array element values similar to mysql like.

Array is as follows.

$arraydata=
  array (0=> array('data'=>1),
  1=> array('data'=>'1|5'),
  2=>array('data'=>'2|3'),
  3=>array('data'=>'1|5|6'),
  4=>array('data'=>'1|5|6|7'),
  5=>array开发者_JAVA百科('data'=>'2|3|4'),
  6=>array('data'=>'2|3|4|8')
);

If want to search "1" in array element 'data' values then the output should be return element 0,1,3,4. If search "2" then output should be return element 2,5,6

There is an optional search parameter in array_keys.

$array = Array(0 => 1, 1 => 0, 2 => 1);
print_r(array_keys($array, 1));

But you appear to be using multi-dimensional arrays -- I'm not sure. You'd be better off using a foreach instead.

$results = Array();
foreach($arraydata as $key => $value) {
  if(strpos($value['data'],'1') !== false) {
    $results[] = $key;
  }
}
