Change in php.ini not reflecting PHP Memory_Limit Master Value

Question

I am trying to install a composer package for AWS S3 integration and came across the Composer Out of Memory issue.

Upon checking phpinfo() I could see the loaded php configuration file is /etc/php.ini and the Max Memory Limit allocated was 256M

But while checking the file memory_limit allocated was 128M. I tried to change it and then restarted the server. But whatever I do the Master value remains at 256M.

I am able to change the values locally using .htaccess but unfortunately it wont work with composer.

Loaded Configuration File

php.ini values

Answer 1

You can search for other instances of the PHP memory_limit setting using the find command.
For example:

find /etc -type f -exec grep -H 'memory_limit' {} \; 

This will search all files (recursively) in /etc that mention memory_limit.

As a note: The composer site suggests values as high as 2gb.

I just had a similar issue with apache and php. My variable was set correctly in the correct php.ini file and I was restarting the apache service but the values for php were not changing until I restarted the whole server. Turns out I was running php-fpm which is its own service (not php running as an apache 'module') and its that service that needs restarting not the apache one. Something along the lines of systemctl restart php-fpm or in my case systemctl restart php8.3-fpm may help
