Anyone come across something like this before?
I have made a little test script as follows:
<?
header ("Content-Type: application/pdf");
$command_line = "/usr/bin/pdflabelseries " .
escapeshellcmd($_POST['labelstart']) . " " .
escapeshellcmd($_POST['labelend']);
exec ("echo \"$command_line\" >/opt/specs/labels.txt");
//passthru($command_line);
?>
The form takes input from a posted form with two variables, labelstart and
labelend. In the above test, if I put in 'start' and 'end' as the posted
variable data, the output from /opt/specs/labels.txt (writable by the http
server) is:
/usr/bin/pdflabelseries start end
All is well and good. Now is where it heads South. I uncomment the
passthru command above. The output from the script in /opt/specs/labels.txt
from the same posted form with the same data entered is now:
/usr/bin/pdflabelseries
pdflabelseries is a C program that I have confirmed works perfectly on the
command line (i.e. generates the requisite pdf file to stdout).
Even if the C program fails (which it does not appear to do from the output
in the httpd logs as it outputs its command line to stderr), surely php
should not lose its own internal variables, especially, for a command that
is executed BEFORE the passthru command.
I am truly baffled.
Any help appreciated.

Mark
