i am trying to switch array value but i get this error message: Undefined offset 2

$at=array(
						  array('Title:','title',2,10),
						  array('First Name:','fname',2,10 ),

i have foreach loop

foreach($at[$s] as $v){
		
switch ($v[2]){

case 2:
if(strlen($_POST[$v[1]]> strlen($_POST($v[2]))   ){
echo 'ok';	
	 }else{
		$ok=false;
	}
break;

Line #6 does this $_POST($v[2]).

Two problems:

1. You should use brackets to fetch array elements, not parenthesis. That is, do: $_POST[$v[2]] instead.
   
2. The value of $v[2] in both the examples you posted is 2. - If your $_POST data does not contain a value for a key named "2", you will get the error message you posted.
   
   You should always use the isset function on input variables before trying to use them. There is always a possibility that they were not sent, and you need to write you code so it can handle that. (That is; output an error message or something.)
