    copied!<p>I'm trying to implement a "find and replace" system for broken links. The problem is, for some links there are no replacements. So, I need to comment out certain li elements. You can see my code below to do this. (I'm starting with an HTML form).</p> <pre><code>&lt;?php $brokenlink = $_POST['brokenlink']; $newlink = $_POST['newlink']; $brokenlink = '"' . $brokenlink . '"'; $newlink = '"' . $newlink . '"'; $di = new RecursiveDirectoryIterator('hugedirectory'); foreach (new RecursiveIteratorIterator($di) as $filename =&gt; $file) { // echo $filename . ' - ' . $file-&gt;getSize() . ' bytes &lt;br/&gt;'; $filetoedit = file_get_contents($file); if(strpos($filetoedit, $brokenlink)) { echo $brokenlink . "found in " . $filename . "&lt;br/&gt;"; $filetoedit = str_replace($brokenlink, $newlink, $filetoedit); file_put_contents($filename, $filetoedit); } } ?&gt; </code></pre> <p>What I want to accomplish is this: If I have a URL, I want to be able to find its li parent. For instance, I want PHP to be able to comment out the code below if the user inputs <a href="http://www.espn.com" rel="nofollow">http://www.espn.com</a> in an HTML form, I want php to find this element on my server:</p> <pre><code> &lt;li&gt;&lt;a href="http://www.espn.com" target="_blank" data-new="20120627"&gt;Sports&lt;/a&gt;&lt;/li&gt; </code></pre> <p>And replace it with this:</p> <pre><code> &lt;!-- &lt;li&gt;&lt;a href="http://www.espn.com" target="_blank" data-new="20120627"&gt;Sports&lt;/a&gt;&lt;/li&gt; --&gt; </code></pre> <p>Is this possible? Thanks.</p>
