PHP method to get the class name and all function names: 1. [get_class(class name)] gets the class name of the class where the current statement is located; 2. [get_class_methods(class name)] gets all the class name method name and form an array.
PHP method to get the class name and all function names:
1. Get the line number, File path file name, class name, method name constants
__LINE__ : The current line number in the file.
__FILE__: The full path and file name of the file.
If used in an include file, returns the include file name. As of PHP 4.0.2, __FILE__ always contains an absolute path, while versions before that sometimes contained a relative path.
__FUNCTION__ : Function name (newly added in PHP 4.3.0).
Since PHP 5, this constant returns the name of the function when it was defined (case-sensitive). In PHP 4 this value is always lowercase.
__CLASS__ : The name of the class (newly added in PHP 4.3.0).
Since PHP 5, this constant returns the name of the class when it was defined (case-sensitive). In PHP 4 this value is always lowercase.
__METHOD__ : The method name of the class (newly added in PHP 5.0.0). Returns the name of the method as it was defined (case-sensitive).
Note: These constants are preceded and followed by two underscores.
