This should work unless some restrictions are set on that PHP installation.  
You may also try simply


 file_get_contents('http://ttc.org.nz/cgi-bin/tuesday.pl');



  $lastline = system ('http://ttc.org.nz/cgi-bin/tuesday.pl', $output);


This would probably never work. You normally cannot execute remote files.


  $retval .= 'b' . $output;
  $lastline = exec ('http://ttc.org.nz/cgi-bin/tuesday.pl', $output);
  $retval .= 'c' . $output;


Same here.


  $lastline = exec(./cgi-bin/tuesday.pl, $output);


This will likely be ../cgi-bin/tuesday.pl with 2 dots, because it looks  
like your running pmwiki.php file is in a directory pmwiki, while the cgi- 
bin directory looks like it is in the document root, and not inside the  
pmwiki directory.



  return $retval;


For testing purposes, in order to see the array values rather than 'Array',  
try


  return pre_r($retval);

A big thanks to Petko and Peter B who got me heading in the right direction.
I've documented this at
http://www.pmwiki.org/wiki/Cookbook/RunCGI

I hope it helps someone else

 This was incorrect, sorry. You can use the pre_r() function on all $output
 variables above, not on $retval:

  $retval .= 'c' . pre_r($output);

[pmwiki-devel] Calling CGI from PHP

2012-09-06 Thread Simon 
I've got a legacy html page http://ttc.org.nz/tuesday.html which calls a
cgi (perl) script !--#include
virtual=/cgi-bin/tuesday.plhttp://ttc.org.nz//cgi-bin/tuesday.pl
--

As an interim step to replacing this script (with something clever from
PmWiki) I've tried to invoke the script from within a recipe on a
pagehttp://ttc.org.nz/pmwiki/pmwiki.php/TTC/Tuesday
.

The recipe is
Markup('ClubNight', 'fulltext', '/\\(:clubnight:\\)/ei',
  Keep(ClubNight()));
function ClubNight() {
  $retval = 'retval is ';
  $lastline = '';
  $output = '';
  // Create a stream
$opts = array(
  'http'=array(
'method'=GET,
'header'=Accept-language: en\r\n
  )
);
  $context = stream_context_create($opts);
// Open the file using the HTTP headers set above
  $retval .= 'a' . file_get_contents('http://ttc.org.nz/cgi-bin/tuesday.pl',
false, $context);
  $lastline = system ('http://ttc.org.nz/cgi-bin/tuesday.pl', $output);
  $retval .= 'b' . $output;
  $lastline = exec ('http://ttc.org.nz/cgi-bin/tuesday.pl', $output);
  $retval .= 'c' . $output;
  $lastline = exec(./cgi-bin/tuesday.pl, $output);
  $retval .= 'd' . $output;

  return $retval;
}

I don't get the result I expect on the
pagehttp://ttc.org.nz/pmwiki/pmwiki.php/TTC/Tuesday
,
and wonder if anyone can spot anything obvious that I have got wrong.
I'm sure safe mode is on.
