foreach ($headers as $header => $value) {
echo "$header: $value <br />\n";
}

Note:
You can also get at the value of the common CGI variables by reading them from the environment, which works whether or not you are using PHP as an Apache module. Use phpinfo() to see a list of all of the available environment variables.
