str_pad pad the input string even when the length of the pad string cannot be evenly dived into the length of the input stirng + pad_length.

This is not necessarily a bug but the behaviour should be documented. I.e. in some cases the user might want the string be padded only with *full-length* pad strings, and not truncated pad strings. 

The following code illustrates:

echo str_pad("1", 2, "AB");

OUPUT:

1A

The output could be viewed as "incorrect" since pad_str was aksed to pad with "AB", not to pad with "A".

Thanks!

Could you state *how* the bug was fixed? i.e. was the behaviour of the function changed or was the documentation changed to explain the current behaviour?

Thanks!

It was closed as a "documentation problem", so it was fixed in the docs.
