I hope you're doing well. I have a question regarding the PHP `flock()` function, and I was wondering if someone could help me out.
So, here is my situation. I am currently working on a web application, and I need to handle file locking to prevent multiple processes from accessing the same file simultaneously. I came across the `flock()` function in PHP, but I'm not entirely sure how to use it correctly.
From my understanding, the `flock()` function is used to acquire an exclusive lock on a file. This means that only one process can hold the lock at a time, preventing other processes from accessing or modifying the same file until the lock is released.
However, I'm not sure about the exact syntax or how to implement it in my code. Can someone please provide me with an example of how to use the `flock()` function effectively? It would be really helpful if you could explain the parameters of the function and their significance.
Any insights, code snippets, or references to helpful resources would be greatly appreciated. Thanks in advance for your time and assistance!
