 * Hello there,
 * I want to convert html template into pdf, for that i need dompdf.
 * I download that from github ([https://github.com/dompdf/dompdf/releases/download/v2.0.0/dompdf_2-0-0.zip](https://github.com/dompdf/dompdf/releases/download/v2.0.0/dompdf_2-0-0.zip))
   extract that and upload into child theme section.
 * In functions.php added following code for testing
 *     ```
       add_action( 'wp_footer', 'temp' );
       function temp(){
       	include_once( get_stylesheet_directory() .'/dompdf/autoload.inc.php');
       	use Dompdf\Dompdf;
       	define('DOMPDF_UNICODE_ENABLED', true);
       	$dompdf = new Dompdf();
       	$dompdf->load_html("<h1>Hello World</h1><p>PDF description</p>");
       	$dompdf->setPaper('A4','potrait');
       	$dompdf->render();
       	$dompdf->stream('title.pdf');

 * If you’re able to rename the HTML file with a .pdf extension, you don’t really
   need dompdf. But you may use it if you prefer.
 * Anyway, when you get that critical error message, you need to check your server’s
   error log to learn what the actual error was so you can take corrective action.
 * While you’re developing new code, it’s a minor hassle to check the log every 
   time any error is introduced. (I tend to make a lot of errors). I like to define`
   WP_DEBUG` as `true` in wp-config.php. Right below that definition, add this line:
   `
   define( 'WP_DISABLE_FATAL_ERROR_HANDLER', true );` With those changes, error 
   messages will appear right on the page, no need to go looking for the error log.
   Don’t leave things this way on a production site (set both to `false` for production),
   visible error messages can be leveraged by hackers to gain useful knowledge about
   your site.

 * Namespace declarations must be [the very first thing in a PHP file](https://www.php.net/manual/en/language.namespaces.definition.php),
   right after the initial `<?php`. Your dompdf code needs to be in its own file,
   which you can then include or require from elsewhere.
