Small question about $this

Question

Excuse me, this $this ——》How do you type the one behind this this? What is it?

Answer 1

Someone has answered the function and I will answer how to use it. . . This is so simple. In non-input method mode, add the - sign to the right of the + sign on the main keyboard 0 and to the left? The > sign to the left of the key, this > can only be typed by holding down the shift key. To switch between input method mode and letter input mode, just press shift.

Answer 2

First of all, you need to understand what $this is and what is its role?

$this is a pointer to the current object. To put it bluntly, it means the previous object. This can realize, for example, class attribute method calls, etc.

Answer 3

$this->So-and-so method.

For example

class man{

function test1(){

$this->test2();

}

function test2(){

echo "hello";

}

}

$m = new man();

$m->test1();

//Output: hello;
