Question

How do I get just the array with value 7? This is just sample data and there may be hundreds of arrays.

This is what I get from print_r. I do not want to loop through the data if possible.

Array
(
[1] => Array
    (
        [0] => 1
    )

[2] => Array
    (
        [0] => 1
    )

[3] => Array
    (
        [0] => 2
        [1] => 1
    )

[4] => Array
    (
        [0] => 3
        [1] => 2
        [2] => 1
    )

[7] => Array
    (
        [0] => 4
        [1] => 3
        [2] => 2
        [3] => 1
    )

[5] => Array
    (
        [0] => 2
        [1] => 1
    )

[6] => Array
    (
        [0] => 5
        [1] => 2
        [2] => 1
    )

)

Not sure if I understand the question correctly, but perhaps:

print_r($arr[7])
