I've been working on a PHP project and came across the `uniqid()` function. I was hoping someone could help me understand this function better and provide some examples of how it can be used.
I've read the documentation, but I'm still a little confused about its purpose and how it works. From what I understand, `uniqid()` generates a unique ID based on the current time in microseconds. But how exactly does it do that?
I'm also curious about the syntax of the function. Are there any parameters that can be passed to it? And what type of value does it return?
Lastly, it would be great if someone could provide some practical examples of how `uniqid()` can be used in real-world scenarios. How can it be integrated into my PHP code to generate unique IDs for various purposes?
Any help would be greatly appreciated. Thank you in advance for your assistance!
