Reusing instance and static function

class me {
   private $name;
   public function __construct($name) { $this->name = $name; }
   public function work() {
       return "You are working as ". $this->name;
   }
   public static function work() {
       return "You are working anonymously"; 
   } 
}

$new = new me();
me::work();

Fatal error: Cannot override me :: work ()

the question is why php does not allow such a review. Is there a workaround?

There is actually a workaround for this, using the creation of the magic method, although I will most likely never do something like this in production code:

__call runs internally when an inaccessible method is called on an object scope.

__callStatic runs internally when an invalid method is called in a static scope.

<?php

class Test
{
    public function __call($name, $args)
    {
        echo 'called '.$name.' in object context\n';
    }

    public static function __callStatic($name, $args)
    {
        echo 'called '.$name.' in static context\n';
    }
}

$o = new Test;
$o->doThis('object');

Test::doThis('static');

?>

Here is how I think you should do it instead:

class me {
   private $name;

   public function __construct($name = null) { 
       $this->name = $name; 
   }

   public function work() {
       if ($this->name === null) {
           return "You are working anonymously"; 
       }
       return "You are working as ". $this->name;
   }
}

$me = new me();
$me->work(); // anonymous

$me = new me('foo');
$me->work(); // foo
