Question

I have a session variable array called ‘section_remember’ with 2 values in it.
I am expecting the code below to result in a single “print_r” and give me two div’s (one for each value in the array).

Instead it executes 2 print_r’s and gives me 4 div’s, if that makes any sense.

If the array has 3 values in it it runs the loop 3 times and results in 3 print_r’s and 9 div’s. And so on depending on the number of values in the array.

I don’t understand why it’s doing this, but I’m new to PHP so I’m hoping it’s something obvious.

<?php
    print_r($_SESSION['section_remember']);

        foreach($_SESSION['section_remember'] as $key =>$value)
        {       
        $sql = "SELECT `section`.`start`,`section`.`stop`,`section`.`title`,`daily_show`.`audio_file`
            FROM `section`
            INNER JOIN `daily_show`
            ON `section`.`daily_show_id` = `daily_show`.`id`
            WHERE `section`.`id` = $value";
        $result = mysql_query($sql);

        while ($query = mysql_fetch_array($result))
        {       
            $title = $query['title'];
            $seconds = $query['seconds'];
            $duration = gmdate ('i:s', $seconds); //'H:i:s' for hours

            echo "<div><span class='duration'>".$duration."</span>".$title."</div>";        
        }   
        }
    ?>

Seeing that the print_r() call is outside the loop and you get it to output three times, that means it’s inside a greater loop (or, say, a function being called three times). The code you’ve sent is not to blame here.
