Extracting associated value of nested array using unique value in PHP - php

Question

I am aware that I could use a loop to answer my question, but I was hoping that maybe PHP has a function to do what I am trying to achieve and that someone might know.
Basically I am trying to identify a unique key from a series of arrays and then extract the value of the correlated key in the array.
So basically, from this array:
$myarray = array(array("id" => 1, "label" => "True"), array("id" => 2, "label" => "False"))
I want to be able to find the label value when the id is searched and matched, i.e. $id = 1 should return True.
Any simple functions available to do this without having to write a couple of loops?

Answer 1

It would be one simple loop. But if you are loopofobic, then you can rely on other functions (that acts as loop too):
function find(array $inputs, int $search): ?string
{
$result = array_filter($inputs, fn ($input) => $input['id'] === $search);
return current($result)['label'] ?? null;
}
$myarray = [["id" => 1, "label" => "True"], ["id" => 2, "label" => "False"]];
var_dump(find($myarray, 1)); // string(4) "True"
var_dump(find($myarray, 2)); // string(5) "False"
var_dump(find($myarray, 3)); // NULL

Answer 2

you may use the built-in function array_column() for your aim.
$myarray = array(array("id" => 1, "label" => "True"), array("id" => 2, "label" => "False"));
/* label (value) per id (key) in 1-dimensional array.*/
print_r(array_column($myarray,'label','id'));
will return
Array
(
[1] => True
[2] => False
)
so you may adjust the code below.
$myarray = array(array("id" => 1, "label" => "True"), array("id" => 2, "label" => "False"));
$id_val = 1;
$output = isset(array_column($myarray,'label','id')[$id_val]) ? array_column($myarray,'label','id')[$id_val] : 'key not found';
var_dump($output);
