PHP check if string is in array

Question

I have an array that looks like this:

{"permissions":["1","2"]}

I'm trying to check if a given string is in the permissions array with the following function

function hasPermission($permission) {
            return in_array($permission, array_column($this->permissions, 'permissions'));
}

When calling the function giving it the string "1" it return false even though 1 is in the permissions array

Any help would be appreciated

Thanks

EDIT

Here is a var Dump of the converted array

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

Did you convert the JSON String to a PHP Object/Array before running this code — RiggsFolly

If you did it woild be useful to see a var_dump() of the Object/Array — RiggsFolly

I converted the array with json_deocde() Here is a var Dump of the converted array array(1) { ["permissions"]=> array(2) { [0]=> string(1) "1" [1]=> string(1) "2" } } — Cleggy1012

Better to edit you question with additional info, nobody can read code in a comment — RiggsFolly

Try like this...

<?php
$json = '{"permissions":["1","2"]}';
$arr = json_decode($json,true);
print_r($arr);
echo in_array(1,$arr['permissions']); // returns 1 if exists
?>

So your function must be like this....

function hasPermission($permission) {
            return in_array($permission, $this->permissions['permissions']);
}

array_column doesn't support 1D arrays, it returns an empty array if so.

Your $permissions array is 1D, so just use $this->permissions['permission'] to access it.

return in_array($permission, $this->permissions['permissions']);

Example:

$array =  ['permissions' => ['1', '2']];
echo (int)in_array('1', array_column($array, 'permissions')); // 0
echo (int)in_array('1', $array['permissions']); // 1

Try this this will work.

$permission = json_decode('{"permissions":["1","2"]}',true);
echo "<pre>";print_r($permission);
if(is_array($permission)){
 echo "this is an array";
}else{
  echo "Not an array";
}

Thanks
