Fatal error: Out of Memory

[abel122]

Hi guys.

I need your expert insight. I am getting Fatal error: Out of memory (allocated 54263808) (tried to allocate 10368 bytes) on jpeg upload and resize. The files do get uploaded but at resizing, the fatal error is thrown on jpegs greater than 2M. Hostgator increased the memory_limit but I still get the error.

Thanks!

What does your code look like? Are you doing anything really really intensive? Are you creating multiple resources of images and not getting rid of them when you're done? Showing your code could help us a lot.

Image manipulation in the PHP GD functions is memory-hungry. Each image that you create via one of the imagecreate type functions creates a bitmap of that image in memory. As such, a bitmap requires much more memory than a compressed format such as a JPEG, the bitmap storing 3 or 4 bytes per pixel while the original JPEG will require only small fraction of that (depending on its compression level). If working with multiple images, be sure to use [man]imagedestroy/man on each image as soon as you are done with it, so that it does not hang around in memory. Other than that, there is no way to force PHP to use less memory if opening up a large image (in pixel dimesions) -- at least no way that I know of.

You could either try increasing the memory_limit directive yourself until it's high enough to work with larger images, or if you're simply resizing images, you might check if your host has ImageMagick installed.
