Question

Suppose both base and son class have a method method_1,

and there’s another method method_2 of base.

inside base::method_2,how can I point $this->method_1 to base::method_1 no matter whether $this is a instance of base or son?

Answer 1

If I understand you correctly, you want something like this:

<?php

class base {
  public function method1() {
    echo "base:method1\n";
  }
  public function method2() {
    if(get_class($this) == 'base') {
      $this->method1();
    }
    else {
      parent::method1();
    }
    echo "base:method2\n";
  }
}



class son extends base {
  public function method1() {
    echo "son:method1\n";
  }
}


$obj = new son();

$obj->method2();

where the call to method2 would always use the base version of the method1.

The best way I could do it is as above, but this code won’t work since base has no parent. I’m pretty sure what you’re trying to do isn’t possible.

This is the error you will get:

PHP Fatal error:  Cannot access parent:: when current class scope has no parent in
