To anybody who tried the digest example above and didn't get it to work.
For me the problem seemed to be the deprecated use of '\' (backslash) in the regex instead of the '$' (Dollar) to indicate a backreference. Also the results have to be trimmed off the remaining double and single quotes.
Here's the working example:
// function to parse the http auth header
function http_digest_parse($txt)
{
// protect against missing data
$needed_parts = array('nonce'=>1, 'nc'=>1, 'cnonce'=>1, 'qop'=>1, 'username'=>1, 'uri'=>1, 'response'=>1);
$data = array();
preg_match_all('@(\w+)=(?:([\'"])([^$2]+)$2|([^\s,]+))@', $txt, $matches, PREG_SET_ORDER);
foreach ($matches as $m) {
$data[$m[1]] = $m[3] ? trim($m[3],"\",'") : trim($m[4],"\",'");
unset($needed_parts[$m[1]]);
}
return $needed_parts ? false : $data;
}
Probably there's a more sophisticated way to trim the quotes within the regex, but I couldn't be bothered :-)
