memcache php responding speed technology improve method cache

本文实例讲述了PHP使用memcache缓存技术提高响应速度的方法。分享给大家供大家参考。具体分析如下:

php虽然己经做到很好很快了,但是如果大数据量时还是会有些卡了,这里介绍一下PHP中使用memcache缓存技术提高响应速度方法,有需要了解的朋友可参考.

memcache既可以在linux下使用,也可以在windows系统下使用,当然首推linux系统,至于如何安装memcache,google一下就什么都出来了.

下面贴一段memcache的使用例子,代码如下:

<?php 
//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."<br>"; 
//保存数据 
$mem->set(&#39;key1&#39;, &#39;This is first value&#39;, 0, 60); 
$val = $mem->get(&#39;key1&#39;); 
echo "Get key1 value: " . $val ."<br>"; 
//替换数据 
$mem->replace(&#39;key1&#39;, &#39;This is replace value&#39;, 0, 60); 
$val = $mem->get(&#39;key1&#39;); 
echo "Get key1 value: " . $val . "<br>"; 
//保存数组 
$arr = array(&#39;aaa&#39;, &#39;bbb&#39;, &#39;ccc&#39;, &#39;ddd&#39;); 
$mem->set(&#39;key2&#39;, $arr, 0, 60); 
$val2 = $mem->get(&#39;key2&#39;); 
echo "Get key2 value: "; 
print_r($val2); 
echo "<br>"; 
//删除数据 
$mem->delete(&#39;key1&#39;); 
$val = $mem->get(&#39;key1&#39;); 
echo "Get key1 value: " . $val . "<br>"; 
//清除所有数据 
$mem->flush(); 
$val2 = $mem->get(&#39;key2&#39;); 
echo "Get key2 value: "; 
print_r($val2); 
echo "<br>"; 
//关闭连接 
$mem->close(); 
?>
Copy after login


例子2,代码如下:

<?php 
//使用memcache缓存 
$mc = memcache_connect(&#39;localhost&#39;, 11211); 
$pn = $mc->get(&#39;pid&#39;); 
echo $pn; 
if($pn<1) $pn = 1; 
else $pn++; 
$mc->set(&#39;pid&#39;,$pn,0,0); //设置永不过期 
memcache_close($mc); 
?>
Copy after login

When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
