    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)

    By : Taoism

    <?php
    /**
    * a variable to control whether debug code is displayed or not
    *
    * @param boolean $debug boolean to toggle debug code showing or not showing
    *
    */
    $debug=true;
    //$debug=false;

    /**
    * simple debug function
    *
    * got this function from the user-feedback section for the
    * print_r php function on www.php.net
    * its very useful for debugging
    *
    * @param mixed $call a variable to be dumped for display
    * @param string $cname a string to describe variable being dumped
    *
    *
    */
    function dp($call,$cname) {
    global $debug;
    if($debug){
    echo "<br/>".$cname.":<pre>";
    if(!is_array($call)){$call=htmlspecialchars($call);}
    print_r($call);
    if(is_array($call)){reset($call);}
    echo "</pre><hr/>\n";
    }//end function dp() ======================
    }//end dp

    /**
    * a function to display multiple variables side-by-side
    *
    * an extended version of dp()
    * it takes an array in and dynamically creates variable names
    * based on the array passed in so that side-by-side
    * comparissons of variables can be done.
    * this is most useful for comparing scopes...
    * i.e. the $_POST scope to the $_SESSION scope...
    * example of a call:
    * dpa(array('xvar'=>'$xvar','AUTH'=>'$AUTH','tmp_AUTH_admin'=>'$tmp_AUTH_admin','x'=>'array_intersect($AUTH["xvar"],$xvar)'));
    * 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
    *
    * @author Keith Young
    * @version 1.0
    * @param array $dbug an array of key=>var pairs where the key is a variable name with no $, and the var is a lable to describe the key
    * @global boolean $debug used to check if the function should run or not
    * @global mixed $key this is a mixed data type based on the key value of the array passed in.
    *
    * @see dp()
