• I can add a few more to the list of things you should dislike about PHP: Can't implement multiple interfaces which both declare the same function

  interface Runnable {
    function run();
  }
  
  interface Task {
    function run();
  }
  
  // won't work
  class Job implements Runnable, Task {
    function run() {
      echo 'run';
    }
  }
  

  Can't initialize a field by calling a function/method

  class Fields {
    private $array1 = array('f', 'o', 'o');
    private $string1 = 'foo';
  
    // the following lines just won't work
    private $foo1 = $this->createFoo();
    private $foo2 = Fields::staticCreateFoo();
  
    private function createFoo() {
      return 'foo';
    }
  
    private static function staticCreateFoo() {
      return 'foo';
    }
  }
  

  Dynamic static method call doesn't work as expected

  // will create a new instance of ClassName;
  $name = "ClassName";
  $instance = new $name();
  
  // will run method().
  public function method() {
    //some code
  }
  $methodName = "method";
  $methodName();
  
  // won't work
  class ClassName {
  
    public static function staticClassMethod() {
      //some code
    }
  
  }
  

  $name = "ClassName"; $name::staticClassMethod(); T_PAAMAYIM_NEKUDOTAYIM Turns out it’s Hebrew for '::'. Thank you, PHP, for teaching me a Hebrew word.
