echo everything in session

[Jerico]

How would I go about printing everything that's currently displayed in the session, without knowing ahead of time what's stored in the session. Just for debugging purposes I want everything in the session and it's values displayed at top of page at all time.

This will echo all the values stored in the session.

foreach($_SESSION as $value){
    echo $value;
} 

So if you have:

<?php

session_start();

$_SESSION['test1'] = "test 1";
$_SESSION['test2'] = "test 2";
$_SESSION['test3'] = "test 3";

foreach($_SESSION as $value){
    echo $value . " | ";
}
?>

It will display:

test 1 | test 2 | test 3 |

I tend to do this since it formats it nicely:

echo sprintf("<pre>%s</pre>", print_r($_SESSION, true));

I tend to do this since it formats it nicely:

echo sprintf("<pre>%s</pre>", print_r($_SESSION, true)); 

You could save yourself a bit of typing by using printf() and losing the echo.

Thanks, I use echo sprintf out of (bad!) habit, I'll have to bear printf in mind.
