我正在尝试将这个页面的标签剥离到可以获取页码列表的程度。所以我可以弄清楚我的 curl 程序继续抓取页面的最高页码是多少。现在,我可以将标签剥离到可以获取数字的程度,但我不知道如何分隔每个数字,因此我可以看到最高页码是多少。
我收到的当前返回值为
12
这是我的代码:
<?php
// Defining the basic pruning function
function scrape_between($data, $start, $end){
$data = stristr($data, $start); // Stripping all data from before $start
$data = substr($data, strlen($start)); // Stripping $start
$stop = stripos($data, $end); // Getting the position of the $end of the data to scrape
$data = substr($data, 0, $stop); // Stripping all data from after and including the $end of the data to scrape
return $data; // Returning the scraped data from the function
}
ob_start();
?>
<span class="current">1</span><a href="javascript:__doPostBack('ctl00$phCenterColumn$motoSearchResults$gvCatalog$ctl01$ctl03','')">2</a><a href="javascript:__doPostBack('ctl00$phCenterColumn$motoSearchResults$gvCatalog$ctl01$ctl04','')">
<?php
$variable = ob_get_clean();
$startend5 = Array('">' => '</a>');
foreach($startend5 as $o => $p){
$data = scrape_between($variable, $o, $p);
}
$data = strip_tags($data);
echo $data;
?>
仅供参考 ob_start(); 和 ob_get_clean(); 仅用于示例不想使代码库超过必要的时间,包括所有 curl 命令。
