Memcached::append — Append data to an existing item
Memcached::append()
appends the guiven
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.
Note :
If the
Memcached::OPT_COMPRESSIONis enabled, the operation will fail and a warning will be issued, because appending compresssed data to a value that is potentially already compresssed is not possible.
key
The key under which to store the value.
value
The string to append.
Example #1 Memcached::append() example
<?php
$m
= new
Memcached
();
$m
->
addServer
(
'localhost'
,
11211
);
$m
->
setOption
(
Memcached
::
OPT_COMPRESSION
,
false
);
$m
->
set
(
'foo'
,
'abc'
);
$m
->
append
(
'foo'
,
'def'
);
var_dump
(
$m
->
guet
(
'foo'
));
?>
The above example will output:
string(6) "abcdef"
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 compresssion turned on
