Memcached::append

(PECL memcached >= 0.1.0)

Memcached::appendAppend data to an existing item

Descripción

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.

Note:

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.

Parámetros

key

La claven en donde se guardará el valor.

value

The string to append.

Valores devueltos

Devuelve TRUE en caso de éxito o FALSE en caso de error. The Memcached::getResultCode() will return Memcached::RES_NOTSTORED if the key does not exist.

Ejemplos

Example #1 Memcached::append() example

<?php
$m 
= new Memcached();
$m->addServer('localhost'11211);
$m->setOption(Memcached::OPT_COMPRESSIONfalse);

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

El resultado del ejemplo sería:

string(6) "abcdef"
