On the mutual invocation _php instance of static method and Non-static method in PHP

Static methods can be invoked in a non-static method of PHP

Class test{public
  
  static function Strprint () {
    echo ' This is strprint static function<br> ';
  }
  
  Public Function Staticfuncinvoke () {
    self::strprint ();
  }
}

$test = new test ();

$test->staticfuncinvoke ();

The above code outputs: This is strprint the static function.

And the following code will be hung directly, PHP directly gives the fatal error:

Fatal error:using $this When isn't in the object context into E:\htdocs\test\content.php on line 6

Class test{public
  
  static function Strprint () {
    $this->staticfuncinvoke ();
  }
  
  Public Function Staticfuncinvoke () {
    echo ' This is a nonstatic function named Staticfuncinvoke ';
  }
}

Test::strprint ();

The above is small series for everyone to talk about static and Non-static methods in PHP all the content of the mutual call, I hope that we support the cloud-Habitat Community ~
