A few debug functions based on a function I got off php.net (original function is included - it is from user notes on php.net)

* got this function from the user-feedback section for the
* print_r php function on www.php.net
* its very useful for debugging

* @param string $cname a string to describe variable being dumped

* Note that the key=>val pairs are VARNAME=>LABLE_TO_DESCRIBE.
* The varname has no $ so that it can be dynamically called within the function

As businesses grow increasingly dependent upon Web applications to provide services to customers, employees and partners, these complex applications become more difficult to secure. Although traditional security solutions protect Internet infrastructure layers, they do not guard against HTTP and HTML attacks. Many organizations that conduct security testing still deploy applications that allow attackers to manipulate their logic and wreak havoc on their business. To mitigate this risk, development and delivery teams must address Web application security throughout the lifecycle, addressing the many layers detailed in this paper.
