PHP get modified array that matches a certain value

Question

I have an array of arrays like below:

        Array
(
    [0] => Array
        (
            [id] => 1
            [uid] => 746
            [lid] => 748
        )

   [1] => Array
        (
            [id] => 6
            [uid] => 746
            [lid] => 744
        )

   [2] => Array
        (
            [id] => 11
            [uid] => 749
            [lid] => 743
        )


)

What I want is to get the modified array that has uid of say 746. So the result I would expect is:

Array
    (
        [0] => Array
            (
                [id] => 1
                [uid] => 746
                [lid] => 748
            )

       [1] => Array
            (
                [id] => 6
                [uid] => 746
                [lid] => 744
            )


    )

Is there any quick way to do it rather than loop through each element and save the matching array to the return array?

There's no way to do it without inspecting each element. That being said you can use array_filter to do this (though it will loop behind the scenes):

$arr = array_filter($arr, function($item){
    return $item['uid'] == 746;
});

Prior to PHP 5.3.0 you will have to declare a function:

function filter746($item){
    return $item['uid'] == 746;
}
$arr = array_filter($arr, 'filter746');
