Memcached::prependPrepend data to an existing item


public bool Memcached::prepend ( string $key , string $value )

Memcached::prepend() prepends the given value string to the value of an existing item. The reason that value is forced to be a string is that prepending mixed types is not well-defined.


If the Memcached::OPT_COMPRESSION is enabled, the operation will fail and a warning will be issued, because prepending compressed data to a value that is potentially already compressed is not possible.



The key of the item to prepend the data to.


The string to prepend.

Valorile întoarse

Întoarce valoarea TRUE în cazul succesului sau FALSE în cazul eșecului. The Memcached::getResultCode() will return Memcached::RES_NOTSTORED if the key does not exist.


Example #1 Memcached::prepend() example

= new Memcached();


Exemplul de mai sus va afișa:

string(6) "defabc"
