I mean throughout, including for these things...
PHP Code:
// in the next four lines change _PDF to either _MSWORD or _MSEXCEL for those binaries
echo "Index the pdf is set to: " . PHPDIG_INDEX_PDF . "<br>";
echo "Parse the pdf is set to: " . PHPDIG_PARSE_PDF . "<br>";
echo "Does parse pdf exist: " . file_exists(PHPDIG_PARSE_PDF) . "<br>";
echo "Is parse pdf executable: " . is_executable(PHPDIG_PARSE_PDF) . "<br>";
It's still using _PDF because "/usr/local/bin/pstotext" is getting printed.
