You can use html_entity_decode to your advantage here.

$searchStr = html_entity_decode($searchStr);
echo preg_replace('/\&num=\d+/i', '', '$searchStr);

Although, you can simply use substr like this

echo substr($searchStr, strpos('&'));

What about a regex that will match anything from the beginning of the string up to the first ampersand ?

/^[^\&]+/
