Why does this not return true?

[maxdefinition]

when I use this code and pass the uId of 55 I expect it to return "cool".

but I get "not" when I type

http://myurl.com/test.php?uId=55

any ideas.


Code:

<?php 

$uId = $_GET['uId']; 

function Secure(){ 
   if($uId == 55){ 
      return true; 
   } 
} 

if(Secure()){ 
   echo "cool"; 
}else{ 
   echo "not"; 
} 
?>

Please help

You need to pass $uId as a parameter in the function

<?php
function Secure($uId)
{
   if($uId == 55)
   {
      return true;
   }
}
?>

or you set $uId as global inside the function

<?php
function Secure(){
global $uId;
   if($uId == 55){
      return true;
   }
}
?>

I would go with the passing to the function method!

or you set $uId as global inside the function

<?php
function Secure(){
global $uId;
   if($uId == 55){
      return true;
   }
}
?>

definitely pass the var as a parameter, globals are evil
