I hope you're all doing well. I have a question regarding the PHP `fflush()` function, and I was wondering if someone could help me out.
So, I have been working on a web application where I need to write data to a file using PHP. I came across the `fflush()` function while looking for ways to ensure that the data is written and saved in the file immediately. However, I'm a bit unsure about how exactly this function works and what its purpose is.
Could someone please explain to me what the `fflush()` function does in PHP and provide an example of how to use it effectively in a web application? I would also appreciate any insights into why and when `fflush()` is particularly useful.
Thank you so much in advance for your kind assistance. I'm looking forward to learning more from the knowledgeable members of this forum.
