I have just started learning PHP and I had a doubt regarding variable names in PHP. I was wondering if anyone could help me understand what characters are allowed in PHP variable names. I tried searching online, but couldn't find a clear answer.
I'm currently working on a project where I need to declare a few variables and I want to make sure I adhere to the proper naming conventions. It would be really helpful if someone could provide me with a list of characters that are allowed in PHP variable names.
Thanks in advance!
