Memcache::flush -- Flush all existing items at the server

## Description

bool Memcache::flush ( void )

Memcache::flush() immediately invalidates all existing items. Memcache::flush() doesn't actually free any resources, it only marks all the items as expired, so occupied memory will be overwritten by new items.

Also you can use memcache_flush() function. See example below.

範例 1. Memcache::flush() example

`<?php /* procedural API */ $memcache_obj = memcache_connect('memcache_host', 11211); memcache_flush($memcache_obj); /* OO API */ $memcache_obj = new Memcache; $memcache_obj->connect('memcache_host', 11211); $memcache_obj->flush(); ?>`

成功回傳`TRUE`失敗回傳`FALSE`。
