    Migrate from Codex:

    Minify HTML codes when page is output

    add_action( 'wp_loaded','my_minify_html' );
function my_minify_html() {
	// Use html_compress($html) function to minify html codes.
	ob_start('html_compress');
}

function html_compress( $html ) {
	// Some minify codes here...
	return $html;
}

    If you only want to load a function only in the front end.

    // If u want to load a function only in the front end.
add_action( 'wp_loaded', 'my_front_end_function');
function my_front_end_function() {
    if ( !is_admin() ) { 
        // Only target the front end
        // Do what you need to do
    }
}

    Same as above, but using anonymous function (PHP 5.3 or higher).

    add_action( 'wp_loaded', function () {
    if ( !is_admin() ) {
        // Only target the front end
        // Do what you need to do
    }
});
