So coming back to my problem with fresh eyes, it looks like the extra lines in robot_functions.php:
Code:
echo "<br>Command is: " . $command . "<br>";
echo "Result contains: ";
print_r($result);
echo "<br>Return value is: " . $retval . "<br><br>";
Are not being run... Which would lead me to think that the switch statement in robot_functions.php (switch ($result_test['status']) is not running and setting $usetool to true.
Any help, any help at all would be greatly appreciated at this point. If I can't get PDF indexing working with phpdig then I'll be forced to use some other search engine and I really like phpdig!
I'm really not any kind of PHP guru at all and I have a suspicion that perhaps my problem stems from the fact the I am forced to be setting phpdig and pdftotext up on a Windows system with IIS... Perhaps some kind of permission problem with the pdftotext executable and the php exec() function, I don't know...
