I've been learning PHP recently, and I came across the concept of local and global variables. I understand that variables in PHP are used to store data, but I'm a bit confused about the difference between local and global variables.
From what I understand, global variables are declared outside of any function and can be accessed from anywhere within the PHP script. On the other hand, local variables are declared within a specific function and can only be accessed within that function.
But I'm wondering, are there any other differences between the two? Are there any limitations or advantages to using one over the other? I'd appreciate it if someone could shed some light on this and help me understand the nuances of local and global variables in PHP.
Thanks in advance!
