[PHP] Missing Array Key with apache_request_headers()
Hello, I don't get this at all. I'm trying to use php to manipulate my HTTP headers. [ Background Info about HTTP headers.] [ If an "ETag" header is sent by the server, then, next time a user-agent requests the same page, it sends back that header's value - in an "If-None-Match" header. ] The problem comes when I try to access the "If-None-Match" header using "apache_request_headers()". With Mozilla (I'm using 1.6b) the "If-Modified-Since" header is in the array. With Internet Explorer 6, it isn't, even though the header is sent out. (I'm checking the header output with the Proxomitron). Why is this happening and what can I do about it? Here are all the details: --- The page I'm testing this with: - The Mozilla output on reload: Array ( [0] => Accept [1] => Accept-Charset [2] => Accept-Encoding [3] => Accept-Language [4] => Cache-Control [5] => Connection [6] => Host [7] => If-None-Match [8] => Keep-Alive [9] => User-Agent ) and from the Prox: GET /test.php HTTP/1.1 Host: pc User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.6b) Gecko/20031208 Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,image/jpeg,image/gif;q=0.2,*/*;q=0.1 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 If-None-Match: asdfghjkl Cache-Control: max-age=0 Connection: keep-alive --- The IE6 output on reload is: Array ( [0] => Accept [1] => Accept-Encoding [2] => Accept-Language [3] => Connection [4] => Host [5] => Pragma [6] => User-Agent ) and from the Prox: GET /test.php HTTP/1.1 Accept: */* Accept-Language: en Accept-Encoding: gzip, deflate If-None-Match: asdfghjkl User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows 98) Host: pc Pragma: no-cache Connection: keep-alive As you can see, in both cases, all the request headers shown by the Proxomitron are also in the array - with the exception, for IE6, of the "If-None-Match" header.

RE: [PHP] Migrating from SSI and Perl
Have I got this right?
I am doing
"$BRPHP" );
exec (' ../cgi-bin/browser.pl', $arr );
echo $arr[2];
echo $arr[3];
echo $arr[4];
echo $arr[5];
echo $arr[6];
?>
1. Am I passing $arr[1] to the perl script?
2. If no, what should I do instead?
3. If yes, how can I access it from the perl script?
(Yes, I know the last question is a perl question, so I'll be happy to just get an
answer to the first two).
Thanks,
Philip Pawley

RE: [PHP] Migrating from SSI and Perl
Right, I used
$output = shell_exec("perl browser.pl");
echo "output";
as Radek suggested. To call my browser-sniffing perl script and read back what the
script prints.
My trouble now is that the perl script, being called by the php script rather than by
SSI, no longer seems to have the cgi environment variables to call on.
I can get the variable using
$BRPHP = $_SERVER['HTTP_USER_AGENT'];
How do I pass this to the perl script? I've followed all the avenues suggested in the
newbie guide.
The best I can seem to manage is to use exec() like so:
$BRPHP = $_SERVER['HTTP_USER_AGENT'];
$arr = array (1 => "$BRPHP" );
exec (' ../cgi-bin/browser.pl', $arr );
echo $arr[2];
echo $arr[3];
echo $arr[4];
echo $arr[5];
echo $arr[6];
The echo commands get me back the script's output, but am I passing $BRPHP to the perl
script this way? (If the answer is "yes" then I can ask the folks at perl.org how to
pick it up in the perl script).
Thanks,

Hi Radek,
I tried to do something with this and failed dismally.
Is it possible for you to give me a really basic working example of what you suggest?
Thanks,
Philip Pawley

[PHP] Migrating from SSI and Perl
I am new to php. My site, at the moment, uses SSI to call a Perl browser-sniffing script. I would like to: 1. use php to call the Perl script. 2. then save the values the Perl script outputs as php variables. Can this be done? If so, how?
