esc_url_raw() WP 2.8.0

Cleans URL for use in database query, redirects, and HTTP requests. Not cleans for a safe display.

Do not use this function if the URL is displayed in HTML code (on the screen). Use esc_url() instead — it replaces HTML entities — it will protect you against XSS attacks

No Hooks.

Return

String. The cleaned URL. Return an empty if the URL contains the protocol not specified in $protocols.

Usage

esc_url_raw( $url, $protocols );

$url(string) (required)

The URL to be cleaned.

$protocols(array)

An array of acceptable protocols. By default: http, https, ftp, ftps, mailto, news, irc, gopher, nntp, feed, telnet.
Default: null

#2 URL cleaning for use in request

$response = wp_remote_get( esc_url_raw( $url ) );
