Codex:

Checks whether a given HTML string is likely an output from this WordPress site.

This function attempts to check for various common WordPress patterns whether they are included in the HTML string. Since any of these actions may be disabled through third-party code, this function may also return null to indicate that it was not possible to determine ownership.


Quellcode

function wp_is_owned_html_output( $html ) {
	// 1. Check if HTML includes the site's Really Simple Discovery link.
	if ( has_action( 'wp_head', 'rsd_link' ) ) {
		$pattern = esc_url( site_url( 'xmlrpc.php?rsd', 'rpc' ) ); // See rsd_link().
		return false !== strpos( $html, $pattern );
	}

	// 2. Check if HTML includes the site's Windows Live Writer manifest link.
	if ( has_action( 'wp_head', 'wlwmanifest_link' ) ) {
		// Try both HTTPS and HTTP since the URL depends on context.
		$pattern = preg_replace( '#^https?:(?=//)#', '', includes_url( 'wlwmanifest.xml' ) ); // See wlwmanifest_link().
		return false !== strpos( $html, $pattern );
	}

	// 3. Check if HTML includes the site's REST API link.
	if ( has_action( 'wp_head', 'rest_output_link_wp_head' ) ) {
		// Try both HTTPS and HTTP since the URL depends on context.
		$pattern = esc_url( preg_replace( '#^https?:(?=//)#', '', get_rest_url() ) ); // See rest_output_link_wp_head().
		return false !== strpos( $html, $pattern );
	}

	// Otherwise the result cannot be determined.
	return null;
