Memcached::append

(PECL memcached >= 0.1.0)

Memcached::append — Append data to an existing item

Description

代码语言:javascript
复制
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.

Parameters

key

The key under which to store the value.

value

The string to append.

Return Values

Returns TRUE on success or FALSE on failure. The Memcached::getResultCode() will return Memcached::RES_NOTSTORED if the key does not exist.

Examples

Example #1 Memcached::append() example

代码语言:javascript
复制
<?php
$m?=?new?Memcached();
$m->addServer('localhost',?11211);
$m->setOption(Memcached::OPT_COMPRESSION,?false);

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

The above example will output:

string(6) "abcdef"
