SplObjectStorage::getInfo — Returns the data associated with the current iterator entry
Returns the data, or info, associated with the object pointed by the current iterator position.
Diese Funktion hat keine Parameter.
The data associated with the current iterator position.
Beispiel #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();
}
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
object(stdClass)#2 (0) {
}
string(2) "d1"
object(stdClass)#3 (0) {
}
string(2) "d2"
