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 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
<?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"
