<function>Memcache::replace</function> should be used to replace value of
|
||
|
|
existing item with <parameter>key</parameter>. In case if item with such
|
||
|
|
key doesn't exists, <function>Memcache::replace</function> returns
|
||
|
|
&false;. For the rest <function>Memcache::replace</function> behaves
|
||
|
|
similarly to <function>Memcache::set</function>.
