Dumping PHP headers

Posted on Mon 07 March 2016 in SysAdmin

I read this somewhere and want to keep it around.

Sometimes I need to debug HTTPS/header issues in a load balanced environment.

Here's how to dump all the headers in PHP:

/* {DocumentRoot}/headers.php
Show all values defined on $_SERVER */
<?php
     while (list($var,$value) = each ($_SERVER)) {
            echo "$var => $value <br />";
     }
?>
