predis3.php代码如下所示:

<?php  
include('runtime.php');  
try\{  
$redis = new Redis();  
$redis->connect('127.0.0.1', 6379);

$runtime= new runtime;  
$runtime->start();  
$redis->pipeline();  
for ($i=0; $i < 100000 ; $i++) \{  
$redis->set("test\_\{$i\}", pow($i, 2));  
$redis->get('test\_\{$i\}');  
\}  
$redis->exec();  
$runtime->stop();  
$runtime->spent($echo = true,'管道执行时间');  
$runtime->clear();  
//平常执行的redis  
$runtime= new runtime;  
$runtime->start();  
for ($i=0; $i < 100000 ; $i++) \{  
$redis->set("test\_\{$i\}", pow($i, 2));  
$redis->get('test\_\{$i\}');  
\}  
$runtime->stop();  
$runtime->spent($echo = true,'平常的redis执行时间');  
$runtime->clear();

//var\_dump($result);  
\}catch (\\Exception $e) \{  
echo $e->getMessage();  
\}  
?>  
runtime.php代码如下所示:

<?php  
/\*\*  
\* PHP脚本执行时间计算  
\*/  
class runtime  
\{  
public $StartTime = 0;  
public $StopTime = 0;

public function get\_microtime()  
\{  
list($usec, $sec) = explode(' ', microtime());  
return ((float)$usec + (float)$sec);  
\}  
public function start()  
\{  
$this->StartTime = $this->get\_microtime();  
\}  
public function stop()  
\{  
$this->StopTime = $this->get\_microtime();  
\}  
public function spent($echo=false,$title='') \{  
$spent = sprintf('%.4f',round(($this->StopTime-$this->StartTime)\*1000,1));  
if($echo) \{  
echo $title."\{$spent\}毫秒<br/>";  
\}else\{  
return $spent;  
\}  
\}

public function clear()  
\{  
$this->StartTime = 0;  
$this->StopTime = 0;  
\}  
  
\}

\#测试脚本代码  
/\*  
$runtime= new runtime;  
$runtime->start();  
$a = 0;  
for($i=0;$i<=10000;$i++) \{  
$a = $i\*$a;  
\}  
$runtime->stop();  
$runtime->spent($echo = true,'执行时间');  
$runtime->clear();  
\*/

执行时间对比如下所示:
