How do I set cookies in PHP?

You can set cookies in PHP using the setcookie() function. It takes parameters like the name, value, expiration time, and path.

Can you show me an example of setting a cookie?

Sure! Here's a simple example:

setcookie('user', 'John Doe', time() + 3600, '/');

This sets a cookie named 'user' with the value 'John Doe' that expires in one hour.

What if I want to set a cookie for a specific path?

You can specify the path in the setcookie() function. For example:

setcookie('user', 'John Doe', time() + 3600, '/myfolder/');

This cookie will only be available in the '/myfolder/' directory.

Are there any limitations on cookie size?

Yes, cookies have a size limit of about 4KB. If you need to store more data, consider using sessions or a database.
