Memcached::append

(PECL memcached >= 0.1.0)

Memcached::appendAppend data to an existing item

Descrierea

public bool Memcached::append ( string $key , string $value )

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.

Notă:

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.

Parametri

key

Cheia sub care se stochează valoarea.

value

The string to append.

Valorile întoarse

Întoarce valoarea TRUE în cazul succesului sau FALSE în cazul eșecului. The Memcached::getResultCode() will return Memcached::RES_NOTSTORED if the key does not exist.

Exemple

Example #1 Memcached::append() example

$m->setOption(Memcached::OPT_COMPRESSIONfalse);

$m->set('foo''abc');
$m->append('foo''def');
var_dump($m->get('foo'));
?>

Exemplul de mai sus va afișa:

string(6) "abcdef"

This method emits this php warning if OPT_COMPRESSION is not explicitly set to false (tested with libmemcached 1.0.18 & pecl-memcached 2.1.0):

PHP Warning:  Memcached::append(): cannot append/prepend with compression turned on
