我正在尝试从网站上获取最新消息并自己包含在内。该站点使用 Joomla (ugh) 并且生成的内容 href 缺少基本 href。
所以链接将保留contensite.php?blablabla，这将导致链接http://www.example.com/contensite.php?blablabla
所以我想在回显之前替换http://为。http://www.basehref.com但我的知识到此为止。
我应该使用哪个：preg_replace，str_replace？我不确定。
include_once('db_connect.php');
// connect to my db
require_once('Net/URL2.php');
include_once('dom.php');
// include html_simple_dom!
$dom = file_get_html('http://www.targetsite.com');
// get the html content of a site and pass it through html simple dom !
$elem2 = $dom->find('div[class=blog]', 0);
// set the div to target for !
$uri = new Net_URL2('http://www.svvenray.nl'); // URI of the resource
$baseURI = $uri;
foreach ($elem2->find('base[href]') as $elem) {
$baseURI = $uri->resolve($elem->href);
}
foreach ($elem2->find('*[src]') as $elem) {
$elem->src = $baseURI->resolve($elem->src)->__toString();
}
foreach ($elem2->find('*[href]') as $elem) {
if (strtoupper($elem->tag) === 'BASE') continue;
$elem->href = $baseURI->resolve($elem->href)->__toString();
}
echo $elem2;
这将修复所有损坏的链接，并且需要 PHP PEAR Net/URL2.php
所以我无法（因为我缺乏 preg 匹配的知识）修复损坏的链接，而是用另一个链接替换它们，并将链接的类替换为我的 fancybox 类，这样它将在花式盒子。
include_once('db_connect.php');
// connect to my db
include_once('dom.php');
// include html_simple_dom!
$dom = file_get_html('http://www.remotesite.com');
// get the html content of a site and pass it through html simple dom !
$elem = $dom->find('div[class=blog]', 0);
// set the div to target for !
$pattern = '/(?<=href\=")[^]]+?(?=")/';
$replacement ='http://www.remotesite.com';
$replacedHrefHtml = preg_replace($pattern, $replacement, $elem);
// replacement 1
// replace the broken links (base href is missing , joomla sucks , period !)
// im to lazy to preg_match it any other way, feel free to improve this !
$pattern2 = '/contentpagetitle/';
$replacement2 ='fancybox fancybox.iframe';
$replacedHrefHtml2 = preg_replace($pattern2, $replacement2,$replacedHrefHtml );
// replacement 2
// replace the joomla class on the links with the class contentpagetitle to my fancybox class ! fancy innit!
$pattern2 = '/readon/';
$replacement2 ='fancybox fancybox.iframe';
$replacedHrefHtml2 = preg_replace($pattern2, $replacement2,$replacedHrefHtml );
// replacement 2
// replace the joomla class on the links with class readon to my fancybox class ! fancy innit!
$replacedHrefHtml3 = preg_replace("/<img[^>]+\>/i", "<br />(Plaatje)<br /><br /> ", $replacedHrefHtml2);
// finally remove the images from the string !
$replacedHrefHtml4 = base64_encode($replacedHrefHtml3);
// encode the html with base64 before store to mysel
// real escape wont work since it will break the links !
try {
$conn = new PDO($link, $pdo_username, $pdo_password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$data222 = $conn->query('SELECT * FROM svvnieuws ORDER BY id DESC LIMIT 1');
foreach($data222 as $row) {
$lastitem = sprintf($row[inhoud]);
}
} catch(PDOException $e) {
echo 'ERROR: ' . $e->getMessage();
}
// get the last stored item in db for comparisation to current result!
if ($replacedHrefHtml4 == $lastitem){
// if the last item from the db is the same, do not store a new item ! importand to prevent clutter !
}
else {
// if its not the same, store a new item !
$conn = new PDO($link, $pdo_username, $pdo_password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// set up the connection to the db
$sql='INSERT INTO svvnieuws (id,inhoud) VALUES ("","'.$replacedHrefHtml4.'")';
// set the mysql query string
$rip = $conn->prepare($sql);
$rip->execute(array(':id'=>$id,
':inhoud'=>$replacedHrefHtml4
));
// insert to the db !
}
// close the else !
// place this file outside of the docroot, and let the cron run it every say 4 hours.
// ofcourse make sure you also place dom.php in the same directory!
// dom.php is my short name for php simple html dom.
因此，replace 1 将
<a href="whatver"> 替换为 <a href="www.remotesite.com"> 替换 2 将 href 上的类替换为 fancybox 替换 3 将 readon 链接上的类替换到 fancybox 与上一个比较存储的项目，如果不同的存储它。
我很想知道如何修复损坏的链接而不是替换它们。该站点的链接源代码如下：<a href="/index.php?blabla">如果可能的话，我如何将 www.mysite.com 注入 <a href="/index.php ?blabla"> 制作 <a href="www.remotesite.com/index.php?blabla">
