I must be doing something wrong! I have a simple CGI script called fred.php, placed in C:\wamp\bin\apache\apache2.2.22\cgi-bin. Code is:
#!php
<?php
echo "Content-Type: text/html\n\n";
echo "<html><head></head><body>\n";
print_r($GLOBALS);
echo "</body></html>\n";
?>
The $_GET array isn't being filled in, even though $QUERY_STRING has the parameter values.
Here is the output when I enter the URL and append some CGI parameters. Any ideas why $_GET is empty? Thanks, Warren

I originally used $_GET, but it was empty. I am printing out $GLOBALS just to see what variables do have values. Note that it shows:
[QUERY_STRING] => fred=cat&dog=jim
[_GET] => Array ( )
which means that $QUERY_STRING has something in it, but $_GET is an empty array. I can't work out how $_GET can be empty when $QUERY_STRING has a value.
Thanks, Warren

Some more data. If the PHP script is in C:\wamp\www, then it works and fills in $_GET. If the same script is in
C:\wamp\bin\apache\apache2.2.22\cgi-bin then the $_GET array is not filled in. OK, so I will stick with the scripts in
the \www directory for now, but I'd still like to know why there is a difference.
Cheers, Warren

Cos the document root is not in apache folder
.
Can you do a print_r of the $_SERVER array in both places
Btw You can specify the cgi bin in the httpd.conf

The $_SERVER array of the script in cgi-bin is included in my original post, look for [_SERVER] => Array ( .... ). Here's the output when the same script is in \www. Note that the $_GET array now has values.
Cheers, Warren
