App Platform Increase PHP LIMIT MEMORY LIMIT

Hi, we’re using Symfony on one of our digital app platform instance. We have a long running process that requires the increase of the php memory limit. Upon checking the /app/.heroku/php/etc/php/php.ini , it always resets back the memory_limit to 128M which is not ideal for processing async long running process.

I already tried the following:

  • PHP_INI_MEMORY_LIMIT to 1024M on the environment variable
  • Added the memory_limit=1024M on my .user.ini file (The other configurations are working like the max_execution_time and post_max_size but I don’t know why the memory_limit=1024M is not picking up.

The quick fix for now that I did was to manually update the memory_limit after deployment but it is cumbersome since I need to do it after deployment.

Thank you in advance!

Hi there,

This is quite interesting, I’ve just tested this and it seems to be working as expected with a .user.ini file:

I’ve just verified this with a demo project that I have here:

Can you also confirm if your app container that you are using has more than 1GB of memory?
