Question

The 3D assoc. array looks like below.

Array 
( 
    [COL] => Array 
                ( 
                    [0] => Array 
                        ( 
                            [emp_num] => 1000001 
                            [user_name] => Test User 
                            [amount] => 775.00 
                            [name] => COL 
                        ) 
                    [1] => Array 
                        ( 
                            [emp_num] => 26 
                            [user_name] => John Doe 
                            [amount] => 555.00 
                            [name] => COL 
                        ) 
                ) 
    [RA. 20%] => Array 
                ( 
                    [0] => Array 
                        ( 
                            [emp_num] => 1000001 
                            [user_name] => Test User 
                            [amount] => 110.00 
                            [name] => RA. 20% 
                        ) 
                ) 
    [BS] => Array 
                ( 
                    [0] => Array 
                        ( 
                            [emp_num] => 1000001 
                            [user_name] => Test User 
                            [amount] => 444.00 
                            [name] => BS 
                        ) 
                ) 
)  

I want to remove the the last key=>value pair of each inner most array. (want to remove the key value pair that has [name] for the key)
The result should look like the array below.

Array 
( 
    [COL] => Array 
                ( 
                    [0] => Array 
                        ( 
                            [emp_num] => 1000001 
                            [user_name] => Test User 
                            [amount] => 775.00
                        ) 
                    [1] => Array 
                        ( 
                            [emp_num] => 26 
                            [user_name] => John Doe 
                            [amount] => 555.00
                        ) 
                ) 
    [RA. 20%] => Array 
                ( 
                    [0] => Array 
                        ( 
                            [emp_num] => 1000001 
                            [user_name] => Test User 
                            [amount] => 110.00
                        ) 
                ) 
    [BS] => Array 
                ( 
                    [0] => Array 
                        ( 
                            [emp_num] => 1000001 
                            [user_name] => Test User 
                            [amount] => 444.00
                        ) 
                ) 
)   

I wrote a function to do this.

<!-- language: php -->    
function remove_name_from_psa($psa_array){

            foreach( $psa_array as $key=>$value ) {
                foreach( $value as $key2=>$value2 ){
                    foreach( $value2 as $key3=>$value3 ){                    
                         if( $key3 != 'name') {
                            $psa_name_removed[$key][$value[$key2][$value2[$key3]]] = $value3;
                        }
                    }
                }
            }
            return $psa_name_removed;
        }  

The returned array is this, which is obviously not what I need.

Array ( [COST OF LIVING] => Array 
                   ( [] => 555.00 ) 
        [RENT ALLOW. 20%] => Array 
                   ( [] => 110.00 ) 
        [BASIC SALARY] => Array 
                   ( [] => 444.00 ) 
      )  

And there are lots of undefined offset and undefined index notices.
$psa_name_removed[$key][$value[$key2][$value2[$key3]]] = $value3; //is this the line I am doing the mistake? Or is the whole method a mistake? 😛
How can I get this to work? Can anyone help?
Thank You!

function remove_name_from_psa($psa_array){

    foreach( $psa_array as $key => $value ) {
        foreach( $value as $key2 => $value2 ){
            unset( $psa_array[$key][$key2]['name'] );
        }
    }
    return $psa_array;

}
