Internal references to private methods in PHP classes

Used to the art and front-end development, now advanced back-end, began to learn PHP, in the Learning class, encountered a private method called the problem.

The code is as follows:

1<?PHP2 classPerson {3      Public functionSay$name,$age) {  4         $con=$this->get ($name,$age);//The $this-> here is the key.5         Echo"My name is:".$name." <br/> "; 6         Echo"My Age is:".$age." <br/> ";7         Echo"Get:".$con." <br/> "; 8     }9     Private functionGet$a,$b) {Ten         $a=$a.$b; One         return $a; A     } -  - }   the  - $person=NewPerson ();  - $person->say ("Ren", 25); -  +?>

This code is very simple and I want to implement the invocation of the inner private method of the class. As shown in line 4th. Used to write JS habit, when calling the Get () method, did not precede the "$this", the program will have a problem. It can be called after it has been made up.
