<!DOCTYPE html><head></head><body></body>...

Can this be achieved with a regular expression??

Any help is appreciated.

    You can use http_parse_headers

    Here’s example:

    $headers = substr($yourString, 0, strpos($yourString, '<!DOCTYPE'));
print_r(http_parse_headers($headers));

    And here’s useful function from docs using Regex (in a case if you don’t have access to PECL library):

    function http_parse_headers( $header )
{
    $retVal = array();
    $fields = explode("\r\n", preg_replace('/\x0D\x0A[\x09\x20]+/', ' ', $header));
    foreach( $fields as $field ) {
        if( preg_match('/([^:]+): (.+)/m', $field, $match) ) {
            $match[1] = preg_replace('/(?<=^|[\x09\x20\x2D])./e', 'strtoupper("\0")', strtolower(trim($match[1])));
            if( isset($retVal[$match[1]]) ) {
                $retVal[$match[1]] = array($retVal[$match[1]], $match[2]);
            } else {
                $retVal[$match[1]] = trim($match[2]);
            }
        }
    }
    return $retVal;
}
