sanitize_url() WordPress Function

The sanitize_url() function is a built-in Wordpress function that is used to clean up and sanitize a URL. This function is especially useful when dealing with user- inputted URLs, as it can help to prevent malicious code from being injected into a site. The sanitize_url() function can also be used to convert a URL into a standard format, which can make it easier to work with.

function sanitize_url( $url, $protocols = null ) {
	return esc_url_raw( $url, $protocols );
