I've been working on a PHP project recently and I've come across the singleton design pattern. I have a class in my project and I'm wondering if it's possible to implement the singleton design pattern in PHP to ensure there will only be one instance of the class throughout my application.
From what I've read, the singleton pattern restricts the instantiation of a class to a single object. This can be really handy when you want to control access to a resource or when you only need a single instance of a class for caching or logging purposes.
I'm a bit new to PHP, so I'm not sure if PHP supports this specific design pattern. I've seen examples in other programming languages like Java or C++, but I haven't found a definite answer for PHP.
If anyone could shed some light on this, I'd really appreciate it. Can I implement the singleton design pattern in PHP? And if so, can you guide me on how to do it or point me towards some helpful resources?
Thanks in advance!
