PHP MEMCACHE進階緩衝應用詳解_PHP教程

Memcache函數庫是在 PECL(PHP Extension Community Library)中，主要作用是搭建大容量的記憶體資料的

臨時存放地區，在分布式的時候作用體現的非常明顯，否則不建議使用。 本人在ubuntu上安裝

完啟動並執行時候報錯：
/usr/local/memcached/bin/memcached: error while loading shared libraries: libevent-1.4.so.2:

cannot open shared object file: No such file or directory

按照：《libeven、memcached、libmemcache安裝》中的方法，使用：

sudo ln -s /usr/local/lib/libevent-1.4.so.2 /usr/lib/libevent-1.4.so.2
可以修正這個BUG

通過新得立安裝php的memcached模組，登出/etc/php5/conf.d/memcached.ini裡面的“;”，重啟apache

，調用phpinfo()出現memcached的資訊

執行：

$memcache = new Memcache;
$memcache->connect(localhost, 11211) or die ("Could not connect");
$version = $memcache->getVersion();
echo "Servers version: ".$version."
";
?>
$memcache = new Memcache;
$memcache->connect(localhost, 11211) or die ("Could not connect");
print_r($memcache->getStats());
/**
