PHP The program can’t start because dll is missing from your computer. Try reinstalling the program to fix this problem.

If you get an system error message something like this: "The program can't start because libcs.dll is missing from your computer. Try reinstalling the program to fix this problem." when to test whether PHP does work from the console
This .dll are: OCI.dll, sqlite3.dll, aspell-15.dll, libcs.dll and maybe some other.
