problem of sending data with the POST method
I have Apache2 server and PHP4 installed on my local computer for educational purposes.
I have the index2.php in my http server directory which prints the myvar variables value.
This thing is working fine when I post data from the index2.htm file,
but it doesn't work when I try to post some data using HttpOpenRequest(...), HttpSendRequest(...) WinINET APIs.
The server respond like it doesn't receive any data.
I posted the optData string with the InternetSendRequest(...)
optData[] = "?myvar=31";
is it right ?
what I made wrong ?
I have the index2.php in my http server directory which prints the myvar variables value.

Try to declare a myvar variable like
global $myvar
If myvar not declared in query it will be empty
$myvar = ""
If you need a specified POST protocol you should check array $_POST (I do not remember how to do it but try to download PHPExpertEditor. This is very useful program with APACHE with PHP on-board and all PHP functions list)
