I'm seeing lots of errors in my log

[25-Aug-2012 14:33:42] PHP Warning:  chmod() [<a

/home/ttc/public_html/pmwiki/cookbook/totalcounter.php on line 1163

Can anyone give me a quick heads up on what might need to be fixed?

I haven't used or reviewed that recipe, but if nothing is mentioned about  
your problem on the cookbook page or on the talk page, and if nobody replies  
on the mailing list, you may try to contact the authors directly -- they may  
be unsubscribed from the mailing lists.

Subject: [pmwiki-devel] Calling CGI from PHP
Message-ID: <CAFUSNWN3oMRXJRjZ5z0AhVDb9xOpdm2FcMBZ0gBYBGF2QJrxHQ@mail.gmail.com>

I've got a legacy html page <http://ttc.org.nz/tuesday.html> which calls a
cgi (perl) script <!--#include
virtual="/cgi-bin/tuesday.pl<http://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
page<http://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
page<http://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.

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);

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

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

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
