$ _GET无法使用＆amp; 在URL中

Question

Im working on a Wix widget. The iframe containing my widget has this URL generated by Wix:

http://domain.com/wix/widget/?cacheKiller=123456&compId=hyeddksh&deviceType=desktop&instance=xxxxxxxxxxxxxx&locale=en&viewMode=editor&width=50

I tried retriving the instance and compId values from the URL using $_GET but no luck.

echo '<pre>';
    print_r($_GET);
echo '</pre>';

gives me

Array
(
    [cacheKiller] => 123456
    [amp;compId] => hyeddksh
    [amp;deviceType] => desktop
    [amp;instance] => xxxxxxxxxxxxxx
    [amp;locale] => en
    [amp;viewMode] => editor
    [amp;width] => 50
)

Any idea about retrieving these values without using $_GET[amp;compId] and $_GET[amp;instance]?

EDIT To solve my issue, I am using $compId = isset($_GET['compId']) ? $_GET['compId'] : $_GET['amp;compId'];which I believe is not the right way. Anyone?

As a mega quick and dirty hack, you could use array_walk.

array_walk($_GET, function($value, $key) use(&$_GET) {
     $_GET[str_replace('amp;', '', $key)] = $_GET[$key];
     unset($_GET[$key]);
});

Then you can use the keys without the amp; prefix.
