• Part of that code got clipped. Not sure what happened but it should have looked like this. class TestLambda { private $test; public function __construct() { $this->test = create_function('$str', 'echo $str;'); } // (John McKnight) This magic method checks for the existence of a function that may have been created using create_function. // Normal methods are unaffected by this code so they should run without issue also. function __call($name, $args) { if (!isset($this->$name)) { echo "Undefined function '{$name}'"; } $function = $this->$name; if (function_exists($function)) { call_user_func_array($function, $args); } } } $l = new TestLambda; // (John McKnight) - But now it works. $l->test("hello world");

• #2 can be made to work using the __call magic method.

  test = create_function('$str', 'echo $str;');
  	}
  	
  	// (John McKnight) This magic method checks for the existence of a function that may have been created using create_function.
  	// Normal methods are unaffected by this code so they should run without issue also.
  	function __call($name, $args) {
  	  if (!isset($this->$name)) {
  	    echo "Undefined function '{$name}'";  
  	  }
  	  
  	  $function = $this->$name;
  	  
  	  if (function_exists($function)) {
  	    call_user_func_array($function, $args);
  	  }
  	}
  }
  
  $l = new TestLambda;
  
  // (John McKnight) - But now it works.
  $l->test("hello world");
  
  ?>
