范例

Example #1 SplObjectStorage::getInfo() example


<?php
$s = new SplObjectStorage();

$o1 = new StdClass;
$o2 = new StdClass;

$s->attach($o1, "d1");
$s->attach($o2, "d2");

$s->rewind();
while($s->valid()) {
    $index  = $s->key();
    $object = $s->current(); // similar to current($s)
    $data   = $s->getInfo();

    var_dump($object);
    var_dump($data);
    $s->next();
}
?>

以上例程的输出类似于：

object(stdClass)#2 (0) {
}
string(2) "d1"
object(stdClass)#3 (0) {
}
string(2) "d2"

This method, SplObjectStorage::getInfo() does NOT exist on PHP 5.2.13. However, PHP 5.3.2 and above does have it. To find out yourself, use this snippet. $> php -r "print_r(get_class_methods(new SplObjectStorage()));" Results for PHP 5.2.13 ==== Array ( [0] => attach [1] => detach [2] => contains [3] => count [4] => rewind [5] => valid [6] => key [7] => current [8] => next [9] => unserialize [10] => serialize ) Results for PHP 5.3.2 ===== Array ( [0] => attach [1] => detach [2] => contains [3] => addAll [4] => removeAll [5] => getInfo [6] => setInfo [7] => count [8] => rewind [9] => valid [10] => key [11] => current [12] => next [13] => unserialize [14] => serialize [15] => offsetExists [16] => offsetSet [17] => offsetUnset [18] => offsetGet )
