Memcached::append — Append data to an existing item
Memcached::append() appends the given value string to the value of an existing item. The reason that value is forced to be a string is that appending mixed types is not well-defined.
Hinweis: If the Memcached::OPT_COMPRESSION is enabled, the operation will fail and a warning will be issued, because appending compressed data to a value that is potentially already compressed is not possible.
Der Schlüssel, unter dem der Wert abgelegt werden soll.
The string to append.
Gibt bei Erfolg TRUE zurück, im Fehlerfall FALSE. The Memcached::getResultCode will return Memcached::RES_NOTSTORED if the key does not exist.
Beispiel #1 Memcached::append() example
<?php
$m = new Memcached();
$m->addServer('localhost', 11211);
$m->setOption(Memcached::OPT_COMPRESSION, false);
$m->set('foo', 'abc');
$m->append('foo', 'def');
var_dump($m->get('foo'));
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
string(6) "abcdef"
