Hi,

I'm writing some debug code. I want to be able to output(print) all session variables and its value, all get variables and its value and all post variables and its value (all with out knowing the variables name, so I can't use $_GET or whatever). Can anybody help me or show me some good debug code.

Why wouldn't you be able to use "$_GET or whatever"? The following function var_dump, dumps out and provides information about, in this case, the arrays. You don't already have to know all possible indices in the arrays. It structures the information in a human-readable format, which is why the <pre> tags are neccessary.

http://www.php.net/var_dump
http://www.php.net/print_r is a simular function but does not provide as much information.

<?php
echo "Session variables:<br />";
    echo "<pre>";
        var_dump($_SESSION);
    echo "</pre>";
echo "Get variables:<br />";
    echo "<pre>";
        var_dump($_GET);
    echo "</pre>";
echo "Post variables:<br />";
    echo "<pre>";
        var_dump($_POST);
    echo "</pre>";

// ...etc
?>

hth,
Rich

I've posted this function before. It's incredibly useful:

function printr($var, $desc = '')
{
   echo "<pre>";
   if ($desc !== '') echo "{$desc}: ";
   print_r($var);
   echo "</pre>\n";
}


This lets you add an optional description to the variable you're printing out. Here are some examples:


$foo = "Some variable.";

printr($_POST, '$_POST before form processing');

if (isset($_POST['username']))
{
    $_POST['username'] = strtolower($_POST['username']);
}

printr($_POST, '$_POST after form processing');

printr($foo); // description parameter is optional.


Take care,
