예제

Example #1 ReflectionClass::isIterateable() example


<?php

class IteratorClass implements Iterator {
    public function __construct() { }
    public function key() { }
    public function current() { }
    function next() { }
    function valid() { }
    function rewind() { }
}
class DerivedClass extends IteratorClass { }
class NonIterator { }

function dump_iterateable($class) {
    $reflection = new ReflectionClass($class);
    var_dump($reflection->isIterateable());
}

$classes = array("ArrayObject", "IteratorClass", "DerivedClass", "NonIterator");

foreach ($classes as $class) {
    echo "Is $class iterateable? ";
    dump_iterateable($class);
}
?>

위 예제의 출력:

Is ArrayObject iterateable? bool(true)
Is IteratorClass iterateable? bool(true)
Is DerivedClass iterateable? bool(true)
Is NonIterator iterateable? bool(false)
