This error message is being presented, any suggestions?
Allowed memory size of 33554432 bytes exhausted (tried to allocate 43148176 bytes) in php
If you are trying to read a file, that will take up memory in PHP. For instance, if you are trying to open up and read an MP3 file ( like, say, $data = file("http://mydomain.com/path/sample.mp3" ) it is going to pull it all into memory.
As Nelson suggests, you can work to increase your maximum memory limit if you actually need to be using this much memory.
