PHP MEMCACHE Detailed Explanation (Classic PHP Cache)_PHP Tutorial

The Memcache function library is in PECL (PHP Extension Community Library). Its main function is to build large-capacity memory data

The temporary storage area is very effective when distributed, otherwise it is not recommended to use it. I installed it on ubuntu

When the operation is completed, an error message is reported:
/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

Follow the method in "libeven, memcached, libmemcache installation" and use:

sudo ln -s /usr/local/lib/libevent-1.4.so.2 /usr/lib/libevent-1.4.so.2
This BUG can be fixed

Install the memcached module of php through Xindili, unregister the ";" in /etc/php5/conf.d/memcached.ini, and restart apache

, calling phpinfo() will display memcached information

Execution:
$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 ());
