Question

I currently have an array set up like this:

$u_id= array(
    array(
        NUM=>'2770', DESC=>'description one'
    ), 

    array(
        NUM=>'33356', DESC=>'description two'
    ), 

    array(
        NUM=>'13576', DESC=>'description three'
    ),

    array(
        NUM=>'14141', DESC=>'description four'
    )
);

I need to be able to pass a number through this array as $num (corresponding to a NUM=>” in the array), and store the corresponding DESC=>” as a string. For example, searching for “2770” would return “description one”.

What would be the best way to go about doing this?

Answer 1

foreach($arrays as $arr){
  if($arr['NUM']==$num){
    return $arr['DESC'];
  }
}
