Body
<p>If you know the name of the element and are truly only after one little thing and the format of the page is always the same, it might be less work to just use <code>curl</code> and <code>explode</code> to parse the document with string compares. This is a quick-and-dirty way to do it, but as long as those two conditions are met this is arguably the fastest way:</p> <pre><code>$url = 'http://example.com/'; $options = array( CURLOPT_RETURNTRANSFER => true, // return web page CURLOPT_HEADER => false, // don't return headers CURLOPT_FOLLOWLOCATION => true, // follow redirects CURLOPT_ENCODING => "", // handle all encodings CURLOPT_USERAGENT => "spider", // who am i CURLOPT_AUTOREFERER => true, // set referer on redirect CURLOPT_CONNECTTIMEOUT => 120, // timeout on connect CURLOPT_TIMEOUT => 120, // timeout on response CURLOPT_MAXREDIRS => 10 // stop after 10 redirects ); $ch = curl_init( $url ); curl_setopt_array( $ch, $options ); $content = curl_exec( $ch ); $err = curl_errno( $ch ); $errmsg = curl_error( $ch ); $header = curl_getinfo( $ch ); curl_close( $ch ); $parts = explode('<input id="ID1" name="NAME1" value="', $content); if (count($parts) == 2) { $value = explode('">', $parts[1]); $value = $value[0]; } else { $value = false; } print 'Value is: ' . $value; </code></pre> <p>Otherwise, you could use regex (again using <code>curl</code> as above):</p> <pre><code>preg_match('/name="NAME1".+value="(.*?)"/i', $html, $value); $value = $value[1]; </code></pre> <p>Finally, if you want to go all-out on this one, you can use a document parser. Be warned, however, that if the HTML you are working with is not properly formed, the parser will have trouble. Here's a tutorial on the subject, using a third-party class: <a href="http://net.tutsplus.com/tutorials/php/html-parsing-and-screen-scraping-with-the-simple-html-dom-library/" rel="nofollow">http://net.tutsplus.com/tutorials/php/html-parsing-and-screen-scraping-with-the-simple-html-dom-library/</a></p>

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.
