Memcached::prepend — Prepend data to an existing item
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.
Bilginize:
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.
key
The key of the item to prepend the data to.
value
The string to prepend.
Başarı durumunda true
, başarısızlık durumunda false
döner.
Returns null
when compression is on.
