Memcached::append

(PECL memcached >= 0.1.0)

Memcached::appendAppend data to an existing item

Descrição

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.

Nota: 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.

Parâmetros

key

The key under which to store the value.

value

The string to append.

Valor Retornado

Retorna TRUE em caso de sucesso ou FALSE em falhas. The Memcached::getResultCode will return Memcached::RES_NOTSTORED if the key does not exist.

Exemplos

Exemplo #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'));
?>

O exemplo acima irá imprimir:

string(6) "abcdef"
