Memcached::append
Memcached::append
(PECL memcached >= 0.1.0)
Memcached::append — Append data to an existing item
Description
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 theMemcached::OPT_COMPRESSIONis 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
<?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"
