What are the magic methods of php7?

The magic method is a special method that overrides the default operation of PHP when performing certain operations on an object.

PHP retains all method names that begin with _ _. Therefore, it is not recommended to use such method names unless you override the behavior of PHP.

Php7 magic methods are:

_ _ constract: triggers when a class is instantiated

_ _ destruct: triggered when an instance object is destroyed

_ _ set (string $name, mixed $value): triggered when an inaccessible member property is set

_ _ get (string $name): triggered when an inaccessible member property is obtained

_ _ call ($name,$arguments): triggered when a member method that is not accessible is accessed

_ _ callStatic ($name,$arguments): triggered when accessing a member static method that is not accessible

_ _ toString: triggered when an object instance is treated as a string

_ _ clone: triggered when a new object is created

_ _ invoke: triggered when an object is called as a function

_ _ sleep: triggered when data processing of an object does not need to save all data, such as when serialize () is serialized

_ _ wakeup: when unserialize (), the _ _ wakeup method is checked first.

_ _ unset (string $name): triggered when an inaccessible object property is unset

_ _ isset (string $name): triggered when an inaccessible object property is isset,empty

_ _ debugInfo: triggered when an object is var_dump

_ _ set_state: triggered when an object is var_export
