Hi,

I am creating a web module in PHP that needs to access a file mostly for reading but there will be times when I need to write to it. The question is how can I safely access the file without two seperate threads accessing the file at the same time for writing, I know I can use flock() but I have been reading that this is not completely reliable. Does anyone know a reliable way to syncronise write access to a file between threads.

thanks.

Firstly the chance that two threads will use the same file at the same time is close to none since it goes so fast.
And secondly use a database system like MySQL.
