    <p>I am trying to obtain data from a Web and show it to the user <strong>using cURL</strong> and Simple HTML Dom PHP class.</p> <p><strong>Some pages have a redirection</strong> depending on the client's language, I am using a function to determine the final page that is to be scraped. </p> <p>In order to show it as the user would see it, I am using this:</p> <pre><code>$useragent = $_SERVER['HTTP_USER_AGENT']; curl_setopt($ch, CURLOPT_USERAGENT, $useragent); </code></pre> <p>At the moment most of my current users are Spanish speakers, therefore I am temporarily limiting accepted languages so if there is a <strong>language redirect on the target page</strong>, it will show Spanish or English first.</p> <pre><code>$header[] = "Accept-Language: es-es,es;q=0.8,en-us;q=0.5,en;q=0.3"; </code></pre> <p>However, since my server is located in the Netherlands and some pages have an <strong>IP-based redirector</strong>, sometimes the pages redirect to the /nl/ directory, ignoring the language parameters.</p> <p>This happens, for example, with the <strong>www.econsultancy.com</strong> Website.</p> <p>Is it possible to avoid this kind of redirect, maybe using the <strong>client's IP address</strong> in the cURL request?</p> <p>Also, is it possible to use the <strong>client's browser language settings</strong> to make the <em>Accept-Language</em> parameter dynamic?</p> <p>Here's the entire function script:</p> <pre><code>&lt;? function redirector($originalurl) { $ch = curl_init(); $useragent = $_SERVER['HTTP_USER_AGENT']; $header[0] = "Accept: text/xml,application/xml,application/xhtml+xml,"; $header[0] .= "text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"; $header[] = "Cache-Control: max-age=0"; $header[] = "Connection: keep-alive"; $header[] = "Keep-Alive: 300"; $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7"; $header[] = "Accept-Language: es-es,es;q=0.8,en-us;q=0.5,en;q=0.3"; $header[] = "Pragma: "; curl_setopt($ch, CURLOPT_HTTPHEADER, $header); curl_setopt($ch, CURLOPT_USERAGENT, $useragent); curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_URL, $originalurl); $out = curl_exec($ch); $out = str_replace("\r", "", $out); $headers_end = strpos($out, "\n\n"); if( $headers_end !== false ) { $out = substr($out, 0, $headers_end); } $headers = explode("\n", $out); foreach($headers as $header) { if( substr($header, 0, 10) == "Location: " ) { $target = substr($header, 10); $targeturl = $target; } } return $targeturl; } ?&gt; </code></pre> <p>Thanks in advance!</p>

    2. COYou have no control over the remote server's redirection settings, so no. edit: @Esailija's suggestion is your only hope.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
