Hello, @agamaleldin

I believe the same question was asked before in our community. Please check this question and the answer from kamaln7

https://www.digitalocean.com/community/questions/how-can-i-increase-the-php-upload-max-filesize-in-app-cloud-platform

“PHP applications on App Platform use PHP-FPM in conjunction with Apache (or Nginx if you choose to use it)—the webserver would accept all incoming requests, and forward PHP requests to PHP-FPM which actually executes them. You’ll want to increase the max upload size there. You can do that by adding a .user.ini file at the root of your app’s document root (in the same directory where you would put an .htaccess file. Usually this will be the public directory) with something like this:

post_max_size = 20M
upload_max_filesize = 5M

post_max_size controls the maximum POST requests body size, while upload_max_filesize controls the maximum allowed size of a single file in an upload request.

For more info, you can refer to the Heroku PHP Buildpack documentation. Let me know if that works!”
