Increase PHP Allowed Memory Limit

We have a Wordpress application hosted and it's running into some memory limit issues. I am curious how we would set the memory limit to be higher?

```[04-Jun-2025 14:25:51 UTC] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 41500672 bytes) in /var/www/html/wp-includes/comment-template.php on line 2423```

Does Railway support any env vars to control this and up the limit? Such as WP_MEMORY_LIMIT?

I believe the proper variable would be PHP_MEMORY_LIMIT. You can specify this to whatever amount you'd like, using the conventional letters. For example. 1024M would be 1024 megabytes.

Yes, it does. It works normally like any other env var.

I'm curious if this is the proper env var? What would be the expected value in bytes or mb?
