Checking if array value exists in a PHP multidimensional array

Question

I have the following multidimensional array:

Array ( [0] => Array 
         ( [id] => 1 
           [name] => Jonah 
           [points] => 27 )

Even though the question is answered, I wanted to post my answer. Might come handy to future viewers. You can create new array from this array with filter then from there you can check if value exist on that array or not. You can follow below code. Sample

$arr = array(
        0 =>array(
                "id"=> 1,
                "name"=> "Bangladesh",
                "action"=> "27"
            ),
         1 =>array(
                "id"=> 2,
                "name"=> "Entertainment",
                "action"=> "34"
                 )
        );

     $new = array();
     foreach($arr as $value){
        $new[$value['id']] = $value; 
     }


    if(array_key_exists(1, $new)){
        echo $new[1]['id'];
    }
    else {
      echo "aaa";
    }
    //print_r($new);
