in_array and annidated path

Hi all sory for the double post but i have deleted the first email that i have send to the list. The problem that i have found is that in_array function don't work with annidate path. I have created a function that update a list of filepath from a directory to DB but when i use particular path with space and more long like: C:\back\Microsoft.NET\Framework\v1.0.3705\file.exe with more iteration there are problem because add the same file again. Can you help me to fix the problem ? I have used this script with CLI but to explain the problem i have added the source to this location: http://www.fadelabot.net/update.php Thanks so much to all and good work. P.S: There is another problem about the CPU usage on windows Xp i have a process php.exe that use 99% of CPU.
