php如何实现文章点击数
php 文件实现文章点击量
<?php error_reporting(E_ALL); $ROOT_PATH = '../'; include_once($ROOT_PATH . "include/config.php"); $update_time = 1800;//多长时间更新一次,单位是秒 $article_id = (isset($_GET['article_id']) && is_numeric($_GET['article_id']) && $_GET['article_id'] > 0) ? intval($_GET['article_id']) : 0;//文章的ID if ($article_id > 0) { $filename = $ROOT_PATH . 'log/click_log.txt'; $s = ''; if (file_exists($filename)) { $content = file_get_contents($filename); $d_ary = array(); if ($content) { $ary = explode("\n", $content); foreach ($ary as $line) { $data_ary = explode('|', $line); if (is_numeric($data_ary[0]) && is_numeric($data_ary[1])) { $d_ary[$data_ary[0]] = $data_ary[1]; } } } if (array_key_exists($article_id, $d_ary)) { $d_ary[$article_id] = $d_ary[$article_id]+1;//将当前的文章的点击数加1 } else { $d_ary[$article_id] = 1; } foreach ($d_ary as $key => $val) { $s .= $key . '|' . $val . "\n"; } } else { $s .= $article_id . '|1' . "\n";//这个是初始化记录文件 } //写记录文件 $fp = fopen($filename, "w"); //加入锁定 if (flock($fp, LOCK_EX)) { // 进行排它型锁定 fwrite($fp, $s); flock($fp, LOCK_UN); // 释放锁定 } //fwrite($fp, $s); fclose($fp); @chmod($filename, 0777); $last_update = file_get_contents('../log/last_update.txt');//取上一次更新的时间 $last_update = intval($last_update); if (($last_update + $update_time) < time()) { //以下是数据库连接操作,我用的是ADODB,你可以改成你自己的 require_once("adodb.inc.php"); $db = NewADOConnection("$DB_TYPE"); $db->debug = true; $ADODB_FETCH_MODE = ADODB_FETCH_ASSOC; if (!$db->Connect("$DB_HOST", "$DB_USER", "$DB_PASS", "$DB_DATABASE")) { exit('<a href="/">服务器忙,请稍候再访问</a>'); } $content = file_get_contents($filename); $d_ary = array(); if ($content) { $ary = explode("\n", $content); foreach ($ary as $line) { $data_ary = explode('|', $line); if (is_numeric($data_ary[0]) && is_numeric($data_ary[1])) { $sql = "UPDATE article SET hits=hits+" . $data_ary[1] . " WHERE id=" . $data_ary[0]; $db->Execute($sql); } } } //点击数更新完了,将这个记录文件清空 $fp = fopen($filename, "w"); fwrite($fp, ''); fclose($fp); @chmod($filename, 0777); //将最后一次更新时间改为当前时间 $fp = fopen('../log/last_update.txt', "w"); fwrite($fp, time()); fclose($fp); @chmod('../log/last_update.txt', 0777); $db->Close();//关闭数据库连接 } exit(); } ?>
首先在log目录下创建last_update.txt
内容是 1155163400,(这是time()函数生成的时间)
click_log文件的内容是像下面这样的:
13136|44 13104|31 23509|32 11407|5 12141|29
第一个数字代表文章的ID,第二个数字代表累积的点击数
这样做,会提高程序的执行效率,无论是动态的PHP页面还是html里,以
<script src="click.php?article_id=333"></script>
这种方法的页面,都很有效.
这个一般用于统计文章等内容的点击数的
一般静态页里,像上面这样用的(可以把我上面的程序存成click.php)
动态页里的话,可以把上面的代码做成一个包含文件,然后在你的文章中include进来,不过,要改一下这个PHP的代码,把article_id传进去.不多说了,PHP程序员都会知道怎么做,不懂程序的话,我讲太多也没用
前些日子因为我服务器上的mysql进程里,经常看见一大堆的update,所以就想了这种缓存更新的方式

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. 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. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
