Question

Does a class need to have the same name as it’s file.

Ex. class.mysql.php and inside it having class mysql (same)

Ex. class.fish.php and inside it having class mysql (diff)

Also can the format for a class file name be name.class.php or does it have to be class.name.php?

Thank You

There is no link between the file name and the class name, you can name the classes in a file anything you want, have multiple classes or have no classes at all. However, it is a good idea to develop a consistent convention to indicate what the file contains via its file name.

Edit:

See Jason McCreary’s answer below as some of these conventions have changed.
