how to capture cgi output

happycloud

I am trying to get the output from a cgi script that I call from inside a php page. I am currently calling it using virtual(). I have had no luck capturing data from the cgi script. Any suggestions? output buffering does not seem to work. The only method that worked was writing and reading a temp file but that's not very efficient. Perhaps returning by reference of some kind? running out of ideas...

Note that I am on safe mode so no eval/system/exec...stuff for me.

virtual() does not work with output buffering in PHP, unfortunately. I have tried the same thing. I ended up shifting virtual() calls around where they wouldn't interfere with the buffering, and I had to convert some of the things to PHP. So you'll either need to do the same, or keep fiddling with writing files like you said.

Ahh... here 'tis!

  ob_start();
  echo "Anything output by php from here up until the ob_get_contents() will NOT be passed on to the browser, but is instead stored in the \$mydata variable as defined below...";
  $mydata=ob_get_contents();
  ob_end_clean();

In the above example, anything you output between the ob_start() and the ob_get_contents functions will be saved in $mydata, as opposed to truly being echo(ed)

That's what I tried at first but virtual doesn't play nice with ob. The only thing that has worked so far is passing a random filename to the script being called by virtual and having it write output to a file with that name which is then read back when virtual is done. Fine for some stuff but not for what I am trying to do. I have tried things like reading stdin instead of a file but that didn't work either. I fimnd it so odd that there is no way to do this. What do all these folks running things like shopping carts as cgi do???

I was thinking $capture = System('cgi-name',1);

Oh.

"Note that I am on safe mode so no eval/system/exec...stuff for me."

$result = readfile('http://mypage.com/cgi-bin/myproggie.cgi');
