The CakePHP app that I'm working on allows the upload of PDF files, and using FPDF, merges those PDFs together. This is the first time that I've seen this issue, but it seems that really large PDFs are breaking they system:
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 41420841 bytes)
I've already changed the php.ini to allow 512M and used ini_set('memory_limit','512M');
, but neither seem to be making a difference.
Any thoughts on how to track down the memory limit?
