I've been trying to understand the PHP `addcslashes()` function and how it works. I've gone through the documentation, but I'm still a bit confused about it. I was hoping someone here could help me out and provide a clear explanation with an example.
To give you some context, I've been working on a project where I need to escape certain characters in a string. I came across the `addcslashes()` function, which seems to be designed for that purpose. However, I'm not entirely sure how to use it correctly.
From what I gather, `addcslashes()` is used to add slashes before specified characters in a string. But when should I use this function? Are there any specific scenarios where it is particularly useful? And what are the characters that I can specify to be escaped?
It would be great if someone could provide me with a practical example that demonstrates how to use `addcslashes()` effectively. I believe that will really help me understand its usage in real-world scenarios.
Thank you in advance for your help!
