Memcache::replace -- Replace value of the existing item


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.

Example 1. Memcache::replace() example


= 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);


Returns TRUE on success or FALSE on failure.
