    A nice way to include Google Analytics and other scripts in the <head> of the document:

    function wpdocs_add_scripts_head() {
    		// Google Analytics
    		$ga_script = "window.ga=window.ga||function(){(ga.q=ga.q||[]).push(arguments)};ga.l=+new Date;ga('create', 'UA-XXXXX-Y', 'auto');ga('send', 'pageview');";
    		echo wp_get_inline_script_tag( $ga_script );
    		echo wp_get_script_tag( array(
    			'async' => true,
    			'src' => 'https://www.google-analytics.com/analytics.js'
    		) );
    	add_action( 'wp_head', 'wpdocs_add_scripts_head', 1 );

    Will output:

    window.ga=window.ga||function(){(ga.q=ga.q||[]).push(arguments)};ga.l=+new Date;ga('create', 'UA-XXXXX-Y', 'auto');ga('send', 'pageview');
    <script async src="https://www.google-analytics.com/analytics.js"></script>%5B/php%5D
