How to pass environment variables to a PHP script

WittRaider

Hi folks,

I am trying to build my of PHP based webserver using the CLI. Internally to thread-safe execute PHP I recursively call it using the php-cgi.exe and a system() call, collecting output buffering... blabla...

The last thing for me to do is being able to pass environment variables to PHP via the CGI... Apache or any other webserver must do the very same thing... just how??? currently my system call looks somewhat like this

ob_start()
system("php-cgi.exe file.php");
$content = ob_get_contents();
ob_end_clean();
//... do something with $content

I have tried to extend the system statement like...

system("php-cgi.exe file.php ".$clientHttpData);

...which didn't work. It would be no problem to set every single variable as I have all values for the needed vars specified in the CGI spec. Just how do I pass them to PHP???

Allright I have my issue solved, and just wanted everyone to know about it in order not to trip over the same things... which actually was a VERY VERY dumb one.

There are basically 2 env-vars needed for PHP to analyse POST:

CONTENT_TYPE and CONTENT_LENGTH

I had those set, but here it comes... You have to use a binary save (rb) stream for the input DOH - pretty obvious. The I now user proc_open to handle the CGI i/o

$process = proc_open($command,array(array("pipe","rb"),array("pipe","w")),$pipes);

if(is_resource($process)) {
fwrite($pipes[0],$inputstream);
fclose($pipes[0]);
while(!feof($pipes[1])) {
$output .= fgets($pipes[1]);
}
fclose($pipes[1]);
$output = trim($output);
proc_close($process);
}

I just didn't use "rb" for reading the stream. Funnily the output stream has to be read with "w" and not "wb"... but works with binaries as well.
