记录与PHP的PK经历

<?php
//连接
$mem = new Memcache;
$mem->connect(“127.0.0.1“, 11211);

//保存数据
$mem->set(‘key1‘, ‘This is first value‘, 0, 60);
$val = $mem->get(‘key1‘);
echo “Get key1 value: “ . $val .“<br>“;

//替换数据
$mem->replace(‘key1‘, ‘This is replace value‘, 0, 60);
$val = $mem->get(‘key1‘);
echo “Get key1 value: “ . $val . “<br>“;

//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 “<br>“;

//删除数据
$mem->delete(‘key1‘);
$val = $mem->get(‘key1‘);
echo “Get key1 value: “ . $val . “<br>“;

//清除所有数据
$mem->flush();
$val2 = $mem->get(‘key2‘);
echo “Get key2 value: “;
print_r($val2);
echo “<br>“;

//关闭连接
$mem->close();
?>

如果正常的话，浏览器将输出：
Get key1 value: This is first value
Get key1 value: This is replace value
Get key2 value: Array ( [0] => aaa [1] => bbb [2] => ccc [3] => ddd )
Get key1 value:
Get key2 value:
