Symfony2：渲染器中的内存耗尽

Question

I have a page in Symfony2 that display a list of search result in a table. I use the JS library gridify to display the result so I have no troubles with the browser, but with Symfony2.

When I have many results (eg 40 000), I have an exception

php.CRITICAL: Fatal Error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 59233802 bytes) 

thrown from PhpEngine->evaluate which does:

ob_start();
require $this->evalTemplate;
$this->evalTemplate = null;
return ob_get_clean();

The memory exception occures on ob_get_clean. I think that the included template is too huge to be included. The memory limit is currently to 512M, I don't want to increase it once more (but with 1024M I have no more problems).

Is there any way (proper or not) in Symfony2 to bypass it?

Answer 1

Technically you can increase the memory_limit at runtime with this line of code:

ini_set('memory_limit', '1024M')

but the hosting provider may have put in place some ways to prevent that.

Anyway, as other have suggested, you may want to find out why so much memory is consumed and possibly optimize the whole process.
