<s>[INST] Hey! In php, when I use `ini_set('memory_limit','6GB');`, it gives blank page? Why is that? [/INST] If using the `ini_set('memory_limit','6GB');` function in PHP is causing your page to go blank, it is likely because the memory limit you are setting is too high for your server to handle.

When you set the memory limit to 6GB, it requires a lot of memory resources to be allocated to your PHP process. If your server does not have enough memory available, it may not be able to allocate the requested amount of memory, which can cause the PHP script to fail and the page to go blank.

To resolve this issue, you can try setting a lower memory limit, such as 512MB or 1GB, and see if that works. Alternatively, you may need to upgrade your server to a higher memory capacity or optimize your PHP code to use less memory.

It's also worth noting that increasing the memory limit too much can lead to performance issues and may not be the best solution to solving memory-related problems in your PHP script. It's important to identify the root cause of the memory issues and address them appropriately to ensure optimal performance and stability of your PHP application.</s>\ <s>[INST] ok [/INST]
