删除数组字段和值

Question

i have the following array when i dd($test) :

array:1 [
  0 => {#81
   +"1": "1"
   +"2": "2"
  }

   +"1": "1"
  }
]

ive been trying to use array_splice and unset but it doesnt get what i want to remove the field and value, am i doing something wrong? how do i make it happen? thanks in advance.

I'm not sure why unset is not working for you, but this code

<?php

$var = [
    0 => [
           "1" => "1",
           "2" => "2",
        ]
    ];

var_dump($var);

unset($var[0]["2"]);

var_dump($var);

Will produce this output:

array(1) {
  [0]=>
  array(2) {
    [1]=>
    string(1) "1"
    [2]=>
    string(1) "2"
  }
}

array(1) {
  [0]=>
  array(1) {
    [1]=>
    string(1) "1" /// leaving only the one you needed
  }
}
