在隐藏的表单输入中提取字符串php的一部分

I accessed a page using php curl that has a form with default values inside hidden inputs, lets say

<input type="hidden" name="foo" value="barbazz">

How do I get the value barbazz, using php, I am thinking of doing this:

...
$re = curl_exec($ch);
curl_close($ch);
$i = strpos('foo') + 11;
$val = substr($re, $i, 7);

Is there a better way to do it?

    $doc = new DOMDocument();
    $doc->loadHTML($your_html);
    

    Read: DOM library.

    Example:

    $html = '<html>
        <body>
            <form>
                <input type="hidden" name="foo" value="barbazz">
                <input type="hidden" name="bar" value="something">
            </form>
        </body>
    </html>';
    
    $doc = new DOMDocument();
    $doc->loadHTML($html);
    
    foreach ($doc->getElementsByTagName('input') as $input) {
        if ($input->getAttribute('name') == 'foo') {
            echo $input->getAttribute('value');
        }
    }
