Hello,
 I have below array , I want to search exact key value array form below array and store in new array
the Key are [5] and [4] and value are [S] and [Red]
that keys come dynamically whether it is one or more than two  
$variant_array  =
Array
(
    [566531271473754110] => Array
        (
            [p_id] => 7113
            [vID] => 56
            [5] => S
            [4] => Red
            [1] => 500
            [2] => 410
            [3] => 15
        )
[286531271473754110] => Array
        (
            [p_id] => 7113
            [vID] => 56
            [5] => S
            [4] => Red
            [1] => 500
            [2] => 420
            [3] => 15
        )

    [566531311473754110] => Array
        (
            [p_id] => 7113
            [vID] => 56
            [5] => M
            [4] => Blue
            [1] => 500
            [2] => 450
            [3] => 10
        )

    [566532101473754110] => Array
        (
            [p_id] => 7113
            [vID] => 56
            [5] => XS
            [4] => Red
            [1] => 500
            [2] => 450
            [3] => 25
        )

)
this is search key value
$val_exp =
Array
(
    [0] => S
    [1] => Red
)
$key_exp
Array
(
    [0] => 5
    [1] => 4
)

this is i had try,

foreach($variant_array as $keys=>$vals)
      {
            foreach($val_exp as $val_key=>$val_val)
            {
                  if($vals[$key_exp[$val_key]] == $val_val && $vals[3] > 0)
                  {
                        $available_variant[$keys] = $vals;
                  }
            }
      }
Please Solve this.

Here is a example

function search($array, $key, $value)
{
    $results = array();

    if (is_array($array)) {
        if (isset($array[$key]) && $array[$key] == $value) {
            $results[] = $array;
        }

        foreach ($array as $subarray) {
            $results = array_merge($results, search($subarray, $key, $value));
        }
    }

    return $results;
}

$arr = array(0 => array(id=>1,name=>"cat 1"),
             1 => array(id=>2,name=>"cat 2"),
             2 => array(id=>3,name=>"cat 1"));

print_r(search($arr, 'name', 'cat 1'));

You can searcht with this function inside a array

Building the array this is wat you do
$arr = array(0 => array(id=>1,name=>"cat 1"),
              1 => array(id=>2,name=>"cat 2"),
              2 => array(id=>3,name=>"cat 1"));

search in the array
$arr is the array
name = the field
cat 1 is the value

 print_r(search($arr, 'name', 'cat 1'));

@Pravin Bnakar: Going forward, please use PHP var_export() to create test data for posting at E-E.  It will generate PHP code from your variables, greatly simplifying the work we need to do to give you tested and working examples.  And please use the code snippet feature when you post code here. Thanks!

Like so many things in software development, the devil is in the details.  For example, we do not know if you want to select an array when only one of the values match.  Or do both of the values have to match?  It's "little things" like this that lead to most programming problems!  But that said, this script uses your test data and shows how to select an array if either  value matches.  Hopefully this can help you get started.
