PHP - Request Exceeded The Limit Of 10 Internal Redirects

Hi All,

Am having a "can't see the wood for the trees" moment

I have a php redirect file which contains my URLs, like so:

return [	
	'/shop/' => '/products/',
];

I then have a functions file which contains:

function 301_redirects(){
    $redirects = include __DIR__ . '/redirects.php';

    if (isset($redirects[$_SERVER['REQUEST_URI']])) {
        header("HTTP/1.1 301 Moved Permanently");
        header('location: ' . $redirects[$_SERVER['REQUEST_URI']]);
        exit;
    }

    if (isset($redirects[rtrim($_SERVER['REQUEST_URI'], '/')])) {
        header("HTTP/1.1 301 Moved Permanently");
        header('location: ' . $redirects[rtrim($_SERVER['REQUEST_URI'], '/')]);
        exit;
    }
										
}

If the URL is https://www.mydomain.com/shop then the redirect won't work

If the URL is https://www.mydomain.com/shop/ then the redirect works

What am I missing? 

Thanks

I have a field gmap  the data would be  a variation of this, the gmap data to place the map on the site. The rest of the string is in my code because I want to size the iframe etc. Whean I use an input form to update this field using Null data and using a simple text line like yellow, the script works, when I try and add data as below I get a 403 error, how can I resolve this?

Should I str_replace all the ! with asccii? or something else?

Anyone have a clue as to why this is happening?
