Re: PHP with CGI

The issue is you are referring to your RPG CGI program by some extension other than .php. The easiest (and I think most secure way) is to use the AddType directive in your Apache configuration and have all .html file processed by PHP. Check out:http://http://www.webmasterworld.com/forum10/5296.htm

What I cannot accomplish, yet, is a configuration that will allow parsing of PHP statements *within* the content returned by the CGI program.

what are you using to interface RPG to CGI? CGIDEV2, xTools...websmart...

there may be some quirk with the interface and not your configuration of the webserver.

Re: PHP with CGI

Hi Tom,

FYI - I am using QtmhRdStin and QtmhWrStout in RPG to read from and write via the HTTP server.

Actually I have now found a solution to my problem.

Instead of my HTML page in the browser posting to the HTTP server and having that invoke a CGI program...my solution is as follows:

The HTML page in the browser posts to a .PHP script (via the ZENDCORE (native) Apache Instance)...it is this PHP script ithat nvokes* the CGI program (which returns an HTML page with embedded PHP)...the .PHP script then parses any embedded PHP using an EVAL operation.

*CGI program is invoked with FPUTS operations after a socket is opened (FSOCKOPEN).

Hey Presto! - My CGI application now supports embedded PHP.

Cheers,

Simon

Cool Simon...If possible post some code snippets so others can "follow" where you have been.

Hi Jamie,

I am writing up the solution for my internal docs...I will try and post some info on this thread when I am done.

Cheers,

Re: PHP with CGI

Hi all,

So...here's a solution for parsing/excecuting PHP embedded in the response from a CGI program.

To recap...

***Scenario:

A CGI (RPG) program is sitting on the System i, that responds to POST requests from a browser (via Apache HTTP server) and sends a HTML page as a response.

*** Problem:

Sadly any PHP code in the HTML page sent from the CGI program to the browser is never parsed/executed.

*** Solution:

Have the HTML page in the browser invoke an intermediate PHP script.

The PHP script sends the POSTed data to the CGI program...and receives the CGI program's response.

When the CGI program sends the response back...the PHP script uses the EVAL statement to parse/execute any embedded PHP and returns the results to the browser.

Hurrah!

Code:

	$postdata = "";
}

// Convert posted data from ISO8859 to IBM-037
$postdata = iconv("ISO8859-1", "IBM-037", $postdata);

// Send posted data to CGI Program ( via Apache Server instance)

function sendToHost($host,$port,$method,$path,$data,$useragent=0)
{

// Supply a default method of GET if the one passed was empty

// Clear the response buffer
$buf = "";

// Populate the response buffer  
while (!feof($fp)) {
$buf .= fgets($fp,128);
}

// Close the socket
fclose($fp);

// Return the response buffer
return $buf;
}
?>
