Well after much stuffing around, I have now installed PHP 5. The is_executable() function not being available for PHP 4 with Windows as I have found out (only took me like 4 hours to get that all worked out!
). So I now am getting the output as below:
Is result test http an array: 1
What is result test http status: HTML
Is result test an array: 1
What is result test status: HTML
Use is executable is set to: 1
Index the pdf is set to: 1
Parse the pdf is set to: D:\Internet\WWWROOT\anmc\Xpdf\pdftotext.exe
Does parse pdf exist: 1
Is parse pdf executable: 1
Still no PDF indexing action to be seen. Any help much appreciated, I think I'm going to now get as far away from the computer as possible before I smash it with a hammer.
