Here is my attempt to create a digest authentication class that will log the user in and out without using a cookie,session,db,or file. At the core is this simple code to parse the digest string into variables works for several browsers.

<?php

// explode the digest with multibrowser support by Tony Wyatt 21jun07

public function explodethedigest($instring) {

$quote = '"';

$equal = '=';

$comma = ',';

$space = ' ';

$a = explode( $comma, $instring);

$ax = explode($space, $a[0]);

$b = explode( $equal, $ax[1], 2);

$c = explode( $equal, $a[1], 2);

$d = explode( $equal, $a[2], 2);

$e = explode( $equal, $a[3], 2);

$f = explode( $equal, $a[4], 2);

$g = explode( $equal, $a[5], 2);

$h = explode( $equal, $a[6], 2);

$i = explode( $equal, $a[7], 2);

$j = explode( $equal, $a[8], 2);

$k = explode( $equal, $a[9], 2);

$l = explode( $equal, $a[10], 2);

$parts = array(trim($b[0])=>trim($b[1], '"'), trim($c[0])=>trim($c[1], '"'), trim($d[0])=>trim($d[1], '"'), trim($e[0])=>trim($e[1], '"'), trim($f[0])=>trim($f[1], '"'), trim($g[0])=>trim($g[1], '"'), trim($h[0])=>trim($h[1], '"'), trim($i[0])=>trim($i[1], '"'), trim($j[0])=>trim($j[1], '"'), trim($k[0])=>trim($k[1], '"'), trim($l[0])=>trim($l[1], '"'));



return $parts;

}

?>
