$_REQUEST value appearing in \'value\'

[Coylee]

i am trying this to pass a value to the next PHP page:\[code\] $("#see_comments").attr({href: "comments.php?aid='"+imgnum+"'"});\[/code\]and in the PHP file I am using:\[code\]$aid = $_REQUEST[aid];echo $aid;\[/code\]but this is displaying the output like this:\[code\]\'9\'\[/code\]why is this happening? //9 is the value i am passing.
