Problem with php script that try to read file while Powerhell writes to it
I have a big problem with a apache server running PHP.
Often some PHP scripts is trying to get data from a CSV file while a Powershell script writes to it.
Is there a common way to prevent this?
I have tied to write to the file at a specific time and then read from the file while no writing is done. But even when I set a read error in the PHP to 20 sec. it often try to read an write at the same time.... HELP!

Can you give the code that read the file in PHP, Do you usefopen()andfRead()or justreadFile()? The first option gives you more options and certainly a way to prevent lock.

I cant add a simple comment because I dont have reputation points... Don't understand that logic but whatever. The most common way of resolving this is using a lock file to signal to another process that the file is in use, check out this little guide:
