Memcached::append — Append data to an existing item

### Descrierea

public Memcached::append ( string `$key` , string `$value` ) : bool

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.

> Notă:

> 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.

### Parametri

`key`

  Cheia sub care se stochează valoarea.

`value`

  The string to append.

### Valorile întoarse

Întoarce valoarea `TRUE` în cazul succesului sau `FALSE` în cazul eșecului. The Memcached::getResultCode() will return `Memcached::RES_NOTSTORED` if the key does not exist.

### Exemple

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'));
?>`

Exemplul de mai sus va afișa:

    string(6) "abcdef"
