Does this answer your question? [PHP - Failed to open stream : No such file or directory](https://stackoverflow.com/questions/36577020/php-failed-to-open-stream-no-such-file-or-directory) — Alon Eitan, Nov 05 '20 at 09:48
This is a pretty much self-explanatory - The path you provided is WRONG — Alon Eitan, Nov 05 '20 at 09:49
@AlonEitan but path is correct my web page location is C:\xampp\htdocs\sms\admin\test.php and the autoload.php file location is C:\xampp\htdocs\sms\mpdf\vendor\autoload.php — roopa, Nov 05 '20 at 09:51
You are using XAMPP (Windows), so you Path is incorrect. Use DIRECTORY_SEPARATOR constant. Your current path is for unix systems. `include('..'.DIRECTORY_SEPARATOR .'mpdf'.DIRECTORY_SEPARATOR .'vendor'.DIRECTORY_SEPARATOR .'autoload.php');` — shelly, Nov 05 '20 at 09:59
Very strange. Does `include( dirname( __FILE__ ) . '/../mpdf/vendor/autoload.php');` change anything? — Alon Eitan, Nov 05 '20 at 09:59
@shelly1337 AFAIK you CAN use `/` as a directory separator in windows (It works fine on my machine), although it's a good practice to use the `DIRECTORY_SEPARATOR` constant — Alon Eitan, Nov 05 '20 at 10:00
@AlonEitan Could be. Last time i worked on windows i didnt worked for me tho. Maybe with wsl. But i could be wrong. — shelly, Nov 05 '20 at 10:02
@shelly1337 On the other hand, [here](https://dev.to/c33s/always-use--as-directory-seperator-in-php-43l7) it say to _Always use `/` as directory separator in php_ (**"windows and php on windows are capable of opening files with the path foo/bar\example/test.txt"**) `:P` I always adding to the root file `define( 'DS', DIRECTORY_SEPARATOR );` and then use a shorter constant - `DS` for more clarity — Alon Eitan, Nov 05 '20 at 10:06

hello @roopa please try this:
1°

// Require composer autoload
require_once __DIR__ . '/vendor/autoload.php';
// Create an instance of the class:
$mpdf = new \Mpdf\Mpdf();

// Write some HTML code:
$mpdf->WriteHTML('Hello World');

// Output a PDF file directly to the browser
$mpdf->Output();

2° If your Root Folder is "mpdf", you don't need to create a new path for that.
include('../mpdf/vendor/autoload.php');
But as you describe on this line, your Root folder should be two folder before vendor folder.

3° The include statement includes and evaluates the specified file.
include('../mpdf/vendor/autoload.php');
In any part of mPDF documentation does not describes or comment the usage of this function

4° Please follow the documentation, it's better! The documentation is easy to read.
https://mpdf.github.io/getting-started/creating-your-first-file.html

In the worst case, make a new installation and all steps if you follow the documentation will be more clear for you!
Good luck!

I always read that we must reqire vendor/autoload.php but there is no such a file inside MPDF folder! Where are you guys getting it from??! — showtime, Jun 20 '22 at 14:15
