删除数组子项，其中value =多维数组中的某个值

Question

I have a multidimentional array like this $membergroups :

Array ( [0] => 
    Array ( [id] => 1645819602 
        [name] => Oryza NurFa 
        [first_name] => Oryza 
        [last_name] => NurFa 
        [work] => MAN 2 Yogyakarta ) 
    [1] => 
    Array ( [id] => 100000251643877 
        [name] => Lathif Pambudi 
        [first_name] => Muhammad Lathif 
        [last_name] => Pambudi 
        [work] => Omah TI ) 
    [2] => 
    Array ( [id] => 1152078197 
        [name] => Novantio Bangun 
        [first_name] => Novantio 
        [last_name] => Bangun 
        [work] => Pertamina))

How to delete one of child array with specific value. For the example, I want to delete an array with [id] => 100000251643877 inside? So the output will be :

Array ( [0] => 
        Array ( [id] => 1645819602 
            [name] => Oryza NurFa 
            [first_name] => Oryza 
            [last_name] => NurFa 
            [work] => MAN 2 Yogyakarta ) 
        [1] => 
        Array ( [id] => 1152078197 
            [name] => Novantio Bangun 
            [first_name] => Novantio 
            [last_name] => Bangun 
            [work] => Pertamina))

Here is my php code, but it doesn't work :

if (($key = array_search($user_fbid, $membergroups)) !== false) {
   unset($membergroups[$key]);
}

Any help would be greatly appreciated. Thank you

Using a foreach you can do the job like this

$id = 100000251643877;//Example
foreach($membergroups as $key => $value){
  if($value['id'] == $id){
    unset($membergroups[$key]);  
  }
}
