Source: http://ruby8.iteye.com/blog/626982 1: Magic function __construct () is called when instantiating an object. When __construct and a function with a class name are present, __construct is called and the other is not called. __destruct () is called when an object is deleted or when an object operation terminates. The __call () object calls a method that is called directly if the method exists, or calls the __call function if it does not exist. __get () when reading an object's properties. If the attribute exists, the property value is returned directly, and if it does not exist, the __get function is called. __set () sets the property of an object. If the attribute exists, it is assigned directly, and if it does not exist, the __set function is called. __tostring () is called when an object is printed. such as Echo $obj, or print $obj; __clone () is called when cloning an object. such as: $t =new Test (), $t 1=clone $t; __sleep () serialize was called before. If the object is relatively large, want to cut a bit of the east and then serialize, you can consider this function. __wakeup () Unserialize is called to do some initialization of the object. __isset () detects if a property of an object is present when it is called. such as: Isset ($c->name). __unset () unset the property of an object is called. such as: unset ($c->name). __set_state () is called when Var_export is called. Use the return value of __set_state as the return value of Var_export. __autoload () when an object is instantiated, the method is called if the corresponding class does not exist. 2: Magic variable __LINE__ returns the current line number in the file. __FILE__ Returns the full path and file name of the file.
