Question

Trying to run a loop based on a session variable.
On the first page load no session.
when it sets the session i sets a session variable and alerts.

Problem being, it alerts every page load 🙁

`
<!-- language: lang-php -->

$check = $_SESSION['cache'];  

if ($check == "xYx") {  

echo $word;  
} else {  

session_start();  
?><script>alert ("Im reading it again !")</script><?  

echo $word;  
$_SESSION['cache'] = "xYx";  
}  

`

Just do this:

session_start();
$check = $_SESSION['cache'];  

if ($check == "xYx") {  

echo $word;  
} else {  

?><script>alert ("Im reading it again !")</script><?  

echo $word;  
$_SESSION['cache'] = "xYx";  
}

Which is just simply moving session_start() to the beginning as the comments said.
