Re: [symfony-users] File Download too big for memory
Hi, if you create the file yourself, you just need to start browser output while you are working on the file and clear the memory of any lines you have produced. I had the same problem, using an array to store all CSV lines, so I count how many lines I have and if it goes over a limit, I print them out and restart.

Re: [symfony-users] File Download too big for memory
I am. The problem is that all the examples I see involve setting the headers for the response (no problem there) and then it loads the file into memory before sending it to the end user for download.

Re: [symfony-users] File Download too big for memory
Hi Gareth , This example is streaming a zip file on the fly - maybe will help in your CSV problem? http://pablotron.org/software/zipstream-php/ Cheers, -Chris Hi all, I need some assistance in creating an action that will generate a CSV file on the server and then push that file for download to the end user. I have written the code to build the csv file and that works no problem. I have found plenty of stuff online about altering the response headers, etc in preparation for the download but they all end up loading the file to download into memory (using readfile()) and I would rather not do that as these CSV could get very very large potentially.

Re: [symfony-users] File Download too big for memory
Off the top of my head, I'd say that you might want to take a look at the stream classes (or functions) in PHP. Mind you, this is just a thought, as I've never done anything like that. ;-) Cheers, Daniel Sent from my iPhone4 On Sep 2, 2010, at 9:42 AM, Gareth McCumskey wrote: > Hi all, > > I need some assistance in creating an action that will generate a CSV file on > the server and then push that file for download to the end user.
