Memcached::append

(PECL memcached >= 0.1.0)

Memcached::appendAppend data to an existing item

Описание

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.

Забележка: 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.

Параметри

key

Ключът, под който да се съхрани стойността.

value

The string to append.

Връщани стойности

Връща TRUE при успех или FALSE при неуспех. The Memcached::getResultCode will return Memcached::RES_NOTSTORED if the key does not exist.

Примери

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'));
?>

Примерът по-горе ще изведе:

string(6) "abcdef"
