PHP24小时自动更新采集标题

大家都知道网站需要时效性强的内容，那么泛目录更注重这点，内容时效性强且及时更新就是泛目录首先要解决的问题。今天，错误博客（cuowu.com）分享的内容为《PHP24小时自动更新采集标题》。希望对大家有所帮助。

一、自动采集原理

自动采集用的是三个php文件，每个文章均放一个header("refresh;url")，A里面放B，B里面放C，C里面放A，开始只需要运行A，那么B过一定时间就会运行一次，B运行时会运行C一次，C运行时会回到A，周而复始，这样子就可以让三个php文件24小时内自动采集了。

header("refresh:600;url=./cuowucom_biaotiA.php");

header("refresh:6;url=./cuowucom_biaotiB.php");

header("refresh:26;url=./cuowucom_biaoti.php");

如下图所示为采集到的标题：

二、PHP采集标题到txt

泛目录程序中需要调用一些时效性强的标题，采用PHP程序实现自动采集并存放到txt中，会很方便。至少比以前介绍的利用宝塔来定时访问要好很多，因为宝塔定时访问可能会增加不少问题出现概率。三个PHP采集中国新闻网的源码如下：

cuowu_biaoti.php

$txtnames ="cuowucom/biaoti/cuowucom-biaoti.txt";
header("refresh:6;url=./cuowucom_biaotiA.php");

function preg_substr($start, $end, $str)
$temp = preg_split($start, $str);
$content = preg_split($end, $temp[1]);
return $content[0];
function str_substr($start, $end, $str)
$temp = explode($start, $str, 2);
$content = explode($end, $temp[1], 2);
return $content[0];
function microtime_float()
list($usec, $sec) = explode(" ", microtime());
return ((float)$usec + (float)$sec);
function getiurl($id)
global $imgline;
$str=$imgline[$id];
return $str;
