php code help needed (url check and change)

How i can add a line of code in php that chechks the image upload url, so that it checks the url and if it has a “?lang=” part in it, it erases that and leaves only the main part.

For example : https://www.website.com/products/?lang=es -> https://www.website.com/products/

and i need it for aqua-resizer to work in multilingual as well.

at the moment i have this line in script:

// Check if $img_url is local.
	if ( false === strpos( $url, $upload_url ) ) return false;

but it only works in local language, not when another language are selected.
