In PHP 7.1, which of the following cast options can be used for explicitly converting a value to integer?

class First { private $foo = 2; protected $bar = 4; protected function A_funct() { return 5; } public function B_funct() { return new class($this->foo) extends First { private $test; public function _construct($foo) { $this->test = $foo; } public function C_funct() { return $this->bar + $this->test + $this->A_funct(); } }; } } echo (new First)->B_funct()->C_funct();?>

var_dump(0 == 'x'); var_dump('2' == '02'); var_dump('20' == '2e2'); var_dump(200 == '2e4'); switch ('x') { case 0: echo '0'; break; case 'x': echo 'x'; break; } ?>

for($a=0,$b=20; $a<50; $a++) { while($b--) { if($b==8) goto end; } } echo 'a = $a'; end: echo ?>

$E_array = array( 'test' => 'code', 64 =>46, 'multi' => array( 'dimensional' => array( 'array' => 'test' ) ) ); var_dump($E_array['test']); var_dump($E_array [64]); var_dump($E_array['multi']['dimensional']['array']); ?>

class Example { public function abcFunction() { return Closure::fromCallable([$this, } private function privateFunction($param) { var_dump($param); } } $expFunc = (new Example)->abcFunction(); $expFunc('My New Example');?>

$sweet = array('1' => 'apple', '2' => 'banana'); $fruits = array('delicious' => $sweet, 'sweet' => 'strawberry'); function myprint($item, $key) { echo '$key is $item\n'; } array_walk_recursive($fruits, 'myprint'); In above code, what is the output?
