    Display Admin notice

    The following example of basic usage of the wp_kses_post() function. We can use it to print the message in the admin screen. 

    if ( ! version_compare( PHP_VERSION, '5.6', '>=' ) ) {	add_action( 'admin_notices', 'wpdocs_fail_php_version' ); } /** * Admin notice for minimum PHP version. * * Warning when the site doesn't have the minimum required PHP version. * * @since 1.0.0 * * @return void */ function wpdocs_fail_php_version() {	if ( isset( $_GET['activate'] ) ) {	unset( $_GET['activate'] );	}	/* translators: %s: PHP version */	$message = sprintf( __( '<strong>My Custom Plugin</strong> requires PHP version %s+, plugin is currently NOT RUNNING.', 'wpdocs-text-domain' ), '5.6' );	$html_message = sprintf( '<div class="error">%s</div>', wpautop( $message ) );	echo wp_kses_post( $html_message ); }
