Body
If you don't have to use curl, here is how you could do it using straight PHP. Note: It is possible to set headers, credentials etc. while using fopen() to fetch URL's using the <a href="http://www.php.net/manual/en/context.http.php" rel="nofollow">HTTP context options</a>. <pre><code><?php class DownloadWithExtension { // array for caching mimetypes public $mimetypes = array(); // create mimetype cache when instantiated public function __construct() { // iterate through /etc/mime.types and create a hash with // mime-types as keys and the first extension as the value. foreach(preg_grep('/(^#)|(^\s+$)/', file('/etc/mime.types'), PREG_GREP_INVERT) as $line) { $minfo = preg_split('/\t+/', $line); if (count($minfo) > 1) { $this->mimetypes[$minfo[0]] = trim(array_shift(explode(' ', $minfo[1]))); } } } // download $url and save as $prefix while automatically // determining appropriate extension. // @param $url - URL to download // @param $prefix - Filename to save to (without extension) // @return filename used public function get($url, $prefix) { $mimetype = NULL; $filename = NULL; $src = fopen($url, 'r'); if (! $src) { throw new Exception('Failed to open: ' . $url); } $meta = stream_get_meta_data($src); foreach($meta['wrapper_data'] as $header){ if (preg_match('/^content-type: ([^\s]+)/i', $header, &$matches)) { $mimetype = $matches[1]; break; } } $extension = @$this->mimetypes[$mimetype]; // default to .bin if the mime-type could not be determined $filename = sprintf('%s.%s', $prefix, $extension ? $extension : 'bin'); $dst = fopen($filename, 'w'); if (! ($dst && stream_copy_to_stream($src, $dst) && fclose($src) && fclose($dst))) { throw new Exception('An error occurred while saving the file!'); } return $filename; } } $d = new DownloadWithExtension(); $url = 'http://example.com?file=3838438'; $filename = $d->get($url, '/tmp/myfile'); print(sprintf("Saved %s as %s\n", $url, $filename)); </code></pre>

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.
