Template:Str rightc/doc



Gives a substring of length of characters from the right-side end of the string. If the parameter 1 is empty, then immediately returns with parameter 3 (or nothing), and skips all the complex processing usually needed to extract a substring.

If is invalid, empty or undefined, this template goes berserk, so don't do that.

Limitations

 * Up to 100 chararacters in the input string. If possible, first check length of input string using Str len. Using strings longer than 100 characters may result in the error "max index is 100 for str_sub ".
 * Limited set of characters.
 * Expensive (if used too many times per page, generates "Wikimedia Foundation Server Error").
 * Returning parameter 3, when parameter 1 is empty, was added 8 May 2010.
