I'm running Postman to send post data to a php page to grab rows from a database and return in json format. The page works fine until I start requesting more than just a few rows of data at which point the response is blank. Thinking maybe something with the type of data in the table, I tried a different table; similar issue. Next thought was perhaps the php framework for queries, so I decided to use composer on the SSH to download Medoo when I ran into this error:
Fatal error: Out of memory (allocated 145752064) (tried to allocate 101 bytes) in phar:///home/user424/public_html/services/includes/composer.phar/src/Composer/Repository/ComposerRepository.php on line 547

Trying different php versions and looking at the php.ini, the memory limit is set to 512M; which I had bumped to 1024M and 2048M. What else to try or where else to look?
