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

A chave sobre a qual guardar o valor.

value

The string to append.

Valor Retornado

Retorna TRUE em caso de sucesso ou FALSE em caso de falha. 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"
