I tried to access the wordnet dictionary as mentioned in: Calling wordnet from php (Wordnet class or API for PHP). It worked fine through command line. Then I tried to use the php function shell_exec() as below to access the dictionary:

<?php 

$output=shell_exec("\Program Files (x86)\WordNet\2.1\bin\wn");
echo $output;
?>

This displays the search option like -ant, -hyp, and so on.i.e it worked fine

But when I tried to add the search option in the above command(as below) it did not work:

<?php 

$output=shell_exec("\Program Files (x86)\WordNet\2.1\bin\wn star -synsn");
echo $output;
?>

or even when I gave space in the command like: 

$output=shell_exec("\Program Files (x86)\WordNet\2.1\bin\wn   ")

it did not work.

Can you please help me what may be the reason for this and any suggestion for the solution?

    The filename does not look valid to me for a windows path. Isn't the drive letter missing? – hakre Jun 15 '11 at 11:16
  • @hakre's comment looks like the answer -- try `C:\Program Files...` etc. – Spudley Jun 15 '11 at 12:45
  • 2)even when i added the drive letter it did not work. the code look like this:$output=shell_exec("C:\Program Files (x86)\WordNet\2.1\bin\wn home -synsn"); – Bikash Jun 15 '11 at 20:32

ok i got the solution now.the problem was because of the spaces between the command.So i handled them as below:

$cmd = '"C:/Program Files (x86)/WordNet/2.1/bin/wn" "home" "-synsn"';
$output=shell_exec($cmd);

thanks to all who responded to my query
