, int &$flags
= ?): string$keys
, array &$flags
= ?): array
Memcache::get() returns previously stored data of
an item, if such key
exists on the server at this
moment.
You can pass array of keys to Memcache::get() to get array of values. The result array will contain only found key-value pairs.
key
The key or array of keys to fetch.
flags
If present, flags fetched along with the values will be written to this parameter. These flags are the same as the ones given to for example Memcache::set(). The lowest byte of the int is reserved for pecl/memcache internal usage (e.g. to indicate compression and serialization status).
Returns the value associated with the key
or
an array of found key-value pairs when key
is an array.
Returns false
on failure, key
is not found or
key
is an empty array.
Example #1 Memcache::get() example
<?php
/* procedural API */
$memcache_obj = memcache_connect('memcache_host', 11211);
$var = memcache_get($memcache_obj, 'some_key');
/* OO API */
$memcache_obj = new Memcache;
$memcache_obj->connect('memcache_host', 11211);
$var = $memcache_obj->get('some_key');
/*
You also can use array of keys as a parameter.
If such item wasn't found at the server, the result
array simply will not include such key.
*/
/* procedural API */
$memcache_obj = memcache_connect('memcache_host', 11211);
$var = memcache_get($memcache_obj, Array('some_key', 'another_key'));
/* OO API */
$memcache_obj = new Memcache;
$memcache_obj->connect('memcache_host', 11211);
$var = $memcache_obj->get(Array('some_key', 'second_key'));
