[PHP] Look for and Trim Last Character

[Karl J. Stubsjoen]

Hello, I'd like to check for a character at the end of a string, if it
exists remove it, example:

Looking for - Z
In string - StringZ
Result would be - String

-or-
Looking for - Z
In string - StringZzz
Result would be - StringZzz (no change)

Thanks!  Karl
BTW:  You guys are great!
