以下程序说明了PHP中的SplObjectStorage::getinfo()函数:

$data = $str->getInfo();
// Print Result
var_dump($object);
var_dump($data);
?>
输出:
object(stdClass)#2 (0) { } string(12) "GeksforGeeks"
示例2:
<?php
// Create an Empty SplObjectStorage
$str = new SplObjectStorage();
$obj1 = new StdClass;
$obj2 = new StdClass;
$obj3 = new StdClass;
$obj4 = new StdClass;
$str->attach($obj1, "GeksforGeeks");
$str->attach($obj2, "GFG");
$str->attach($obj3);
$str->attach($obj4, "DSA");
$str->rewind();
// Iterate and print data on each index
while($str->valid()) {
$index = $str->key();
$object = $str->current();
$data = $str->getInfo();
var_dump($object);
var_dump($data);
$str->next();
}
?>
输出:
object(stdClass)#2 (0) { } string(12) "GeksforGeeks" object(stdClass)#3 (0) { } string(3) "GFG" object(stdClass)#4 (0) { } NULL object(stdClass)#5 (0) { } string(3) "DSA"
