I hope you're all doing well. I have been working on a PHP project recently, and I came across the concept of the singleton design pattern. I've been doing some research on it, but I'm still a bit confused about how to handle it properly in PHP classes.
To give you some context, in my project, I have a class that I want to restrict to only having a single instance at any given time. From what I understand, the singleton design pattern ensures that there is only one instance of a class throughout the application's lifecycle.
I would appreciate it if someone could guide me on how to implement the singleton design pattern in PHP classes. Are there any best practices or specific guidelines that I should follow? And how can I make sure that the singleton instance is accessible from different parts of my application?
Any tips, examples, or explanations would be greatly appreciated. Thank you in advance for your help!
