FuelPHP Forums

In previous applications I used a PHP $_SESSION and it worked with no problems. I introduced the following code to a Fuel application and the counter is being updated by 2 instead of 1. If I increment by Zero then the counter is not updated. Any suggestions to fix the problem so the counter is only updated by one? // index.php

<?php
 session_start();
if(isset($_SESSION['counter']))
&#123;
 $_SESSION['counter'] = 1 + $_SESSION['counter'];    // adds 2
 // $_SESSION['counter'] = 1 + (int) $_SESSION['counter'];  // adds 2
 // $_SESSION['counter'] = 0.1 + $_SESSION['counter']; // adds 0.2
 // $_SESSION['counter'] = 0 + $_SESSION['counter'];  // does not add anything 
}
else
&#123;
 $_SESSION['counter'] = 0; // start  counter
}

// toggle previously used in a class, model or view
// usually either 0 or 1 - true or false
if( $_SESSION['counter'] % 2) 
&#123;
   // do this 
}
else
&#123;
  // do that
}

Update:
I just cleared the session and the counter sequence is:
0
1
3
5
7 Updated again:
Counter works fine using iExplorer, FireFox, Opera and Safari. Only adds two using Chrome.
