Question

I am quite confused whether is it possible to get the request date on HTTP Request. Like in the Response header:

Date: Thu, 20 Oct 2011 03:03:40 GMT

I tried var_dump(apache_request_header()) and print_r($_SERVER) to attempt if the request date is in there, but no luck.

Any ideas? Thanks.

Answer 1

apache_request_header does not return the Request Date/Time. It mainly has the following information

Accept: */*
Accept-Language: en-us
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0
Host: www.example.com
Connection: Keep-Alivev

The best way to find out when the page was requested is to use.

$_SERVER[’REQUEST_TIME’] 

Using $_SERVER is more reliable and uses less resources.

EDIT

$DT = date("D, d M Y H:i:s", $_SERVER['REQUEST_TIME']);
echo "Time page was requested: ",$DT;

Will output something like the folowing

Time page was requested: Thu, 20 Oct 2011 23:02:29
