I have recently started working on a project in PHP and I am currently dealing with sets and collections. I was wondering if there are any built-in operators or functions specifically for working with sets or collections in PHP.
I am aware that PHP has various array functions like `array_intersect`, `array_diff`, etc., which can be used for manipulating arrays. However, I am specifically looking for operators or functions that are designed to work with sets or collections.
If anyone has any suggestions or knows of any operators/functions that can help with this, I would greatly appreciate it. Thanks in advance for your help!
