Introduction to php magic method __invoke

illustrate

1. Directly call the object name. When the method is used, the __invoke() method is called.

2. The object itself cannot be used directly as a function. If you remove the __invoke() method and still use the object as a method, an error will be reported.

Example

 <?php
class autofelix
{
public function __invoke()
{
echo 'Do you still want to call me?';
}
}

$a = new autofelix();

//The object is directly used as a function call $a();

//Result: Do you still want to call me?

The above is an introduction to the PHP magic method __invoke. I hope it will be helpful to everyone.
