PHP Calling a static function -

-

given following code looking pro's , con's of calling $this->mystaticfunc(); vs self::mystaticfunc();

class myclass    private function myprivatefunc() {     ...     $this->mystaticfunc(); // or self::mystaticfunc();     ...   }    // no need tell me can't use $this in here   public static function mystaticfunc() { ... }  }  // access static function myclass::mystaticfunc();

the cons of using $this->mystaticfunction() are:

  • it doesn't indicate intend (-> indicates doing object, but aren't),
  • it may wind calling didn't expect,
  • it confuse reader (all reader able determine sure author doesn't understand basic oo principles),
  • and it's wrong: static functions belong classes, not objects. call them through class (including self), not object.

the possible pro may want override static function in child class, indicates function belongs object , not class. in case more appropriate use instance method.
