searching for key in multidimensional array by sub array value

Question

I am trying to unset an array by value. I only have the ExerciseID and need to unset the array that it belongs too.

My array is structured like so:

Array
(
[0] => Array
    (
        [ExerciseID] => 644
        [Sets] => 
        [Reps] => 
    )

[1] => Array
    (
        [ExerciseID] => 33
        [Sets] => 
        [Reps] => 
    )
)

Many thanks in advance.

Loop through the array and check for the ExerciseID key in your array with the value of your ExerciseID and if found , unset and break up from the loop.

$exid=33;
foreach($arr as $k=>$arr1)
{
    if($arr[$k]['ExerciseID']==$exid)
    {
        unset($arr[$k]);
        break;
    }
}

print_r($arr);

OUTPUT :

Array
(
    [0] => Array
        (
            [ExerciseID] => 644
            [Sets] => 
            [Reps] => 
        )

)
