I do not understand this atall.
"PHP Magic constants
PHP provides a large number of predefined constants to any script which it runs.
There are five magical constants that change depending on where they are used. For example, the value of LINE depends on the line that it's used on in your script. [b]These special constants are [u]case-insensitive[/u] and are as follows[/b] −".
The class name. (Added in PHP 4.3.0) As of PHP 5 this constant returns the class name as it was declared [b]u[/u][/b]. In PHP 4 its value is always lowercased.
The class method name. (Added in PHP 5.0.0) The method name is returned as it was declared [b]u[/u][/b].
Seems like contradiction to me. Firs they say case-insensitive. Then in their 2 examples they mention they are case-sensitive. What is going on ? I need some good explanation with a min of 2 good examples to understand any of this.
