Memcache::replace

Description

bool Memcache::replace ( string key, mixed var [, int flag [, int expire]] )

Memcache::replace() should be used to replace value of existing item with key. In case if item with such key doesn't exists, Memcache::replace() returns FALSE. For the rest Memcache::replace() behaves similarly to Memcache::set().

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

Beispiel 1. Memcache::replace() example <?php $memcache_obj = memcache_connect('memcache_host', 11211); /* procedural API */ memcache_replace($memcache_obj, "test_key", "some variable", false, 30); /* OO API */ $memcache_obj->replace("test_key", "some variable", false, 30); ?>

Gibt bei Erfolg TRUE zurück, im Fehlerfall FALSE.
