Use the array_filter function with an anonymous function to return the items that contain the desired value.

Examples

If the value "Yes" is always in position 2 of the subarray:

$novoArray = array_filter($seuArray, function($arr) {
    return $arr[2] == 'Sim';
})

If you are in any position:

$novoArray = array_filter($seuArray, function($arr) {
    return in_array('Sim', $arr);
});
