How can I search in nested arrays?

Question

I have a variable which is containing these nested arrays:

echo $var;



/* Output:

Array(

       [0] => Array

         (

             [id] => 1

             [box] => 0

         )



       [2] => Array

         (

             [id] => 2

             [box] => 0

         )



       [3] => Array

         (

             [id] => 3

             [box] => 1

         )

) */

Now I would like to know, is there any

[box] => 1

in

$var

? How can I do that? Actually I can search in array by

in_array()

function, but I don't know how can I do that for nested arrays?

You could use array_column:

$index = array_search(1, array_column($var, 'box'));
