A PHP uses memcache caching technology to improve response speed. Friends in need can refer to it.

Connect to database

//Replace data$mem->replace('key1′, 'This is replace value', 0, 60);

The code is as follows

代码如下

复制代码

$memcache_obj = memcache_connect(”localhost”, 11211);

memcache_add($memcache_obj, ’var_key’, ’test variable’, false, 30);

$memcache_obj->add(’var_key’, ’test variable’, false, 30);

Copy code

$memcache_obj = memcache_connect("localhost", 11211);

代码如下

复制代码

//连接
$mem = new Memcache;
$mem->connect(“127.0.0.1″, 11211) or die (“Could not connect”);
//显示版本
$version = $mem->getVersion();
echo “Memcached Server version: “.$version.”
”;
//保存数据
$mem->set(‘key1′, ‘This is first value’, 0, 60);
$val = $mem->get(‘key1′);
echo “Get key1 value: ” . $val .”
”;
//替换数据
$mem->replace(‘key1′, ‘This is replace value’, 0, 60);
$val = $mem->get(‘key1′);
echo “Get key1 value: ” . $val . “
”;
//保存数组
$arr = array(‘aaa’, ‘bbb’, ‘ccc’, ‘ddd’);
$mem->set(‘key2′, $arr, 0, 60);
$val2 = $mem->get(‘key2′);
echo “Get key2 value: “;
print_r($val2);
echo “
”;
//删除数据
$mem->delete(‘key1′);
$val = $mem->get(‘key1′);
echo “Get key1 value: ” . $val . “
”;
//清除所有数据
$mem->flush();
$val2 = $mem->get(‘key2′);
echo “Get key2 value: “;
print_r($val2);
echo “
”;
//关闭连接
$mem->close();
?>

memcache_add($memcache_obj, 'var_key', 'test variable', false, 30);

$memcache_obj->add('var_key', 'test variable', false, 30);

The code is as follows

”;
//Save data
$mem->set('key1′, 'This is first value', 0, 60);
$val = $mem->get('key1′);echo “Get key1 value: ” . $val .”
”;

$val = $mem->get('key1′);echo “Get key1 value: ” . $val . “

Its main function is to build a temporary storage area for large-capacity memory data , which is used when distributed The reflection is very obvious, otherwise Internet marketing training is not recommended. Memcache::add - Adds a value, returns false if it already exists Memcache::addServer - Adds a server address for use Memcache::close - Closes a Memcache object Memcache::connect - Create a Memcache objectmemcache_debug - Control the debugging function!
