Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

See http://www.php.net/manual/en/function.strrchr.php.

As described in the documentation, strrchr() doesn't work in the opposite way of strchr().

Hello Moriyoshisan

I know the manual by hart :-)

I read in it:
This function returns the portion of haystack which starts at the last occurrence of needle and goes until the end of haystack. 

In my sample, it prints "wings" if I use the word "drawings" and what is expected, "/wip/drazings" if I use the word "drazings". This is not a bug ?

Thanks for your consideration.

Does your copy of the manual also have the sentence:

  If needle contains more than one character, the first is used.

Yes :-( 
Sorry.
Thanks.
