This article will explain in detail what is the use of call magic methods in php. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

The php "_ _ call ()" magic method is called when calling a method that does not exist or is inaccessible. Its purpose is to let the program continue to execute and avoid causing an error to cause the program to terminate when the called method does not exist or is inaccessible.

In object-oriented programming, PHP provides a series of magic methods, which provide a lot of convenience for programming, and play a very important role in PHP. Magic methods in PHP usually start with _ _ (two underscores) and do not need to be called explicitly but automatically under certain conditions.

Among them, the _ _ call () or _ _ callStatic () methods are designed to achieve overloading, so let's introduce the _ _ call method.

Php _ _ call magic method

The _ _ call () method is called when a method that is inaccessible or does not exist in the class is called. The syntax format of this method is as follows:

Public function _ call ($name, $arguments) {...;}

Where $name is the name of the method to be called, and $arguments is an array of parameters passed to $name.

The _ _ call () method is called automatically when the called method does not exist, and the program continues to execute, thus avoiding program termination caused by an error when the calling method does not exist.

[example] the following uses a simple example to demonstrate the use of the _ _ call () method.
