Memcache::get
(PECL memcache:0.2-2.1.2)
Memcache::get — Retrieve item from the server
说明
Memcache::get() returns previously stored data if an item with 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.
参数
- 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).
返回值
Returns the string associated with the key or FALSE on failure or if such key was not found.

<?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.
