Are there any specific PHP functions or libraries recommended for parsing and organizing data from complex strings like UPNP queries?

When parsing and organizing data from complex strings like UPNP queries in PHP, the use of regular expressions can be very helpful. PHP's `preg_match_all` function can be used to extract specific data patterns from the string and organize them into an array for further processing. 

// Sample UPNP query string
$upnpQuery = 'M-SEARCH * HTTP/1.1
Host: 239.255.255.250:1900
Man: "ssdp:discover"
ST: ssdp:all';

// Regular expression pattern to extract key-value pairs from the UPNP query
$pattern = '/(\w+): (.+)/';

// Initialize an array to store the extracted key-value pairs
$data = [];

// Use preg_match_all to extract key-value pairs from the UPNP query
preg_match_all($pattern, $upnpQuery, $matches, PREG_SET_ORDER);

// Organize the extracted data into an associative array
foreach ($matches as $match) {
    $key = $match[1];
    $value = $match[2];
    $data[$key] = $value;
}

// Output the organized data
print_r($data);
