Answer 1

You are just using substr wrong.

To get the last character you have just use negative offset: substr($path,-1)

Your code lacks 2 fundamental things, essential for the programming:

• debugging
• documentation reading.

Debugging is as simple as just echoing your variables.
by echoing substr($path, 0, -1) you can make yourself aware that your code is somewhat wrong and by reading documentation you can see the right usage.
