I can't see what's wrong with the following code.  It only does one iteration.
$_SESSION['Left_Bldg_Count'] displays "8".
$count display "0" on the one iteration.
$_SESSION['Left_Bldg'][$count]['SEQ'] show the correct data.

<?php
      $count = 0;
      echo "Left = ";
      echo $_SESSION['Left_Bldg_Count'];
      echo "<br>";
      while ($_SESSION['Left_Bldg_Count'] <= $count);
      {
            echo $count;
            echo "<br>";
            echo "Seq = ";
            echo $_SESSION['Left_Bldg'][$count]['SEQ'];
            echo "<br>";
            $count++;
      }
?>      
I know it's something stupid.

Change <= to >=.

Otherwise, it reads:

while(8 <= 0)
{
 ...
}
0

You could also do:

<?php
      echo "Left = ";
      echo $_SESSION['Left_Bldg_Count'];
      echo "<br>";

for($count = 0; $count <= $_SESSION['Left_Bldg_Count']; $count++)
{
            echo $count;
            echo "<br>";
            echo "Seq = ";
            echo $_SESSION['Left_Bldg'][$count]['SEQ'];
            echo "<br>";
}

Open in new window


That way, the for loop automatically declares and increments $count for you.

Thanks.  I've been staring at this all day.  Some time you need a new fresh of eyes.
