php setAttribute替换＆with＆amp;

Question

I'm trying to do somwthing like this (where $doc is a DOMDocument)

$link_found = $doc->getElementsByTagName('a');

foreach ($link_found as $idx => $link) {
    $link->setAttribute('href', "/test.php?t=1&q=2" ) ;
}

All is working, but in the href now I got

"/test.php?t=1&q=2" 

I need the literal &, not encoded in &

I need

 "/test.php?t=1&q=2"

Like a common query string

Answer 1

Standards require that & be escaped if it is not introducing an entity, even if it is in an attribute.

(That's got to be the most i_ words I've used in a single sentence... ever...)
