I'm relatively new to PHP and I've been trying to understand how to define constants in PHP. I know that constants are used to store values that cannot be changed throughout the execution of a script. I've been looking at some PHP code examples, but I'm still a bit confused about the correct syntax for defining constants.
Could someone please provide me with the correct syntax for defining constants in PHP? I would really appreciate a clear explanation or maybe even a simple code example to help me understand how it works.
Thanks in advance!
