Awesome response speed!!! Why commercial product support does not work like this?
Good news first!
You are absolutely right about the compatibility issue which cannot be compromised. Btw your patch works like a dream.
Then some clarification about external binary usage in Windows.
What I posted earlier was a cure for antiword but pdftotxt did not like it. It seems to be so that numbers are not recognized in name extension at all. So I removed '.2' from all lines in $command definitions.
Then there is a part of code that I don't understand at all. What is the meaning of
PHP Code:
rename($tempfile,$tempfile.'2'); and unlink($tempfile.'2');
These are not affecting at all?!
After commenting out those lines also pdf documents can be spidered. And $suffix can be the default one.
Maybe there is already threads about these issues but I couldn't find any. Hopefully this will help others to solve problems in Windows.
