Question

I’m using the Symfony2 Framework with Doctrine using a mysql database, when running a Symfony command on the command line such as …

/path/to/php app/console myCommand

This command is to update loads of records (about 35,000+) and I get a memory exhaustion at 1Gb, is there a better and probably more efficient way to run these commands so I dont get this issue?

I could increase the memory limit but ultimately this is going to fail again at some point.

Thanks in advance

Try using batch processing To handle the updates in chunks.
