$matches = array();
foreach ($blocks as $i => $block) {
    $parsed[$i] = array();
    $lines = preg_split('/\n(([\w.-]+)\: *((.*\n\s+.+)+|(.*(?:\n))|(.*))?)/',
                        $block, -1, PREG_SPLIT_DELIM_CAPTURE);
    foreach ($lines as $line) {
        if(preg_match('/^\n?([\w.-]+)\: *((.*\n\s+.+)+|(.*(?:\n))|(.*))?$/',
                      $line, $matches)) {
            $parsed[$i][$matches[1]] = preg_replace('/\n +/', ' ',
                                                    trim($matches[2]));
        }
    }
}

print_r($parsed);
