    [ratio] => Array
        (
            [0] => Array
                (
                    [assigned_to] => 12 
                    [ratio] => 5
                )

            [1] => Array

                    [assigned_to] => 13 
                    [ratio] => 3

        )

Hello all ! I am struck in one problem. This is my array getting after form submit and I just want to check whether key assigned_to is present for at least once. If it is not present then it should show error message. How can I do that?

simple use array_column to get the specific column from multidimensional array . if the count of array is more than zero key exists otherwise key not exists so show the error message .

if(count(array_column($array['ratio'],'assigned_to'))>0){

  echo "key exist in the multi-dimensional array";

}else{

   echo "key not present ";   
}
