I'm developing a web application and have it with some beta testers. Some are reporting that their servers have PHP 4 or better installed, but the program does not work because they receive lots of warning messages. The warnings are all related to the fact that, though PHP is active on the server, permissions have not been set to allow creating files or subdirectories.
This is my first PHP project - question: any idea - roughly - what percent of commercial hosts make PHP available on their clients' accounts, but turn off file creation for security reasons?
It doesn't make sense to me, since I would figure that most PHP applications would need to create files for one reason or another.....
