Memcached::append

(PECL memcached >= 0.1.0)

Memcached::appendAppend data to an existing item

Açıklama

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

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

Bilginize:

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

This method emits this php warning if OPT_COMPRESSION is not explicitly set to false (tested with libmemcached 1.0.18 & pecl-memcached 2.1.0):

PHP Warning:  Memcached::append(): cannot append/prepend with compression turned on
