# Memcached::flush

(PECL memcached >= 0.1.0)

Memcached::flush — Invalidate all items in the cache

### Descrição

public bool Memcached::flush ([ int `$delay` = 0 ] )

Memcached::flush() invalidates all existing cache items immediately (by default) or after the `delay` specified. After invalidation none of the items will be returned in response to a retrieval command (unless it's stored again under the same key after Memcached::flush() has invalidated the items). The flush does not actually free all the memory taken up by the existing items; that will happen gradually as new items are stored.

### Parâmetros

`delay`

  Numer of seconds to wait before invalidating the items.

### Valor Retornado

Retorna `TRUE` em caso de sucesso ou `FALSE` em falhas. Use Memcached::getResultCode se necessário.

### Exemplos

Exemplo #1 Memcached::flush() example

`<?php
$m = new Memcached();
$m->addServer('localhost', 11211);
/* flush all items in 10 seconds */
$m->flush(10);
?>`
