调用追踪器的方法

复制代码 代码如下:

$Profiler = $Db -> getProfiler();

复制代码 代码如下:

/*
追踪器的使用方法
*/

//引入Loader类(自动加载类)
require_once("Zend/Loader.php");
//使用Loader类引入一个Db类
Zend_Loader::loadClass("Zend_Db");
//引入Zend_Db的状态器
Zend_Loader::loadClass("Zend_Db_Statement_Pdo");
//配置数据库连接信息
$Config = array('host' => '127.0.0.1' ,
    'username' => 'root' ,
    'password' => '111' ,
    'dbname' => 'test',
    'profiler' => "true"
    );
//告诉Zend_Db类所操作的数据库和数据库配置信息
$Db = Zend_Db::factory('PDO_Mysql' , $Config);
//执行编码语句
$Db -> query("set names utf8");
//-----------------------------------------------------
$Sql = "select * from gongsi";
$Db -> query($Sql);
//调用追踪器的方法
$Profiler = $Db -> getProfiler();
//获取提交语句的条数
echo "提交的个数:" . $Profiler -> getTotalNumQueries() . "
";
//获取SQL语句执行的信息
$Result = $Profiler -> getQueryProfiles();
foreach ($Result as $key => $value)
{
 //输出运行过的语句
 echo "文本内容为:" . $value->getQuery() . "
";
 //输出运行语句所花费的时间
 echo "花费时间为:" . $value->getElapsedSecs() . "
";
}
//输出所有语句花费的总时间
echo "花费的总时间为:" . $Profiler -> getTotalElapsedSecs();
?>
