Late static binding is used in PHP to:

  2. Use caller class information provided in static method call
  3. Resolve undefined class names by automatically including needed files
  4. Find proper method to call according to the call arguments

Answer(s): B



What is the output of the following code?
class Test {
public function __call($name, $args)
{
call_user_func_array(array('static', "test$name"), $args);
}
public function testS($l) {
echo "$l, ";
}
}
class Test2 extends Test {
public function testS($l) {
echo "$l, $l, ";
}
}
$test = new Test2();
$test->S('A');

  1. A,
  2. A, A,
  3. A, A, A,
  4. PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback

Answer(s): B

How should class MyObject be defined for the following code to work properly? Assume $array is an array and MyObject is a user-defined class.
$obj = new MyObject();
array_walk($array, $obj);

  1. MyObject should extend class Closure
  2. MyObject should implement interface Callable
  3. MyObject should implement method __call
  4. MyObject should implement method __invoke

Answer(s): D



Consider the following code. What change must be made to the class for the code to work as written?
class Magic {
protected $v = array("a" => 1, "b" => 2, "c" => 3);
public function __get($v) {
return $this->v[$v];
}
}
$m = new Magic();
$m->d[] = 4;
echo $m->d[0];

  1. Nothing, this code works just fine.
  2. Add __set method doing $this->v[$var] = $val
  3. Rewrite __get as: public function __get(&$v)
  4. Rewrite __get as: public function &__get($v)
  5. Make __get method static

Answer(s): D
