How can one determine if a browser can read a compressed stream in PHP?

To determine if a browser can read a compressed stream in PHP, you can check the 'HTTP_ACCEPT_ENCODING' header of the request. If the header contains 'gzip' or 'deflate', then the browser supports compressed streams. 

if (strpos($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip') !== false || strpos($_SERVER['HTTP_ACCEPT_ENCODING'], 'deflate') !== false) {
    // Browser supports compressed streams
    echo "Browser supports compressed streams";
} else {
    // Browser does not support compressed streams
    echo "Browser does not support compressed streams";
}
