Offset also does not work from the end:
strrpos with offset
string: aaabaaaaaaaaaaaabaaa
strrpos($string, 'b', 1): 16
strrpos($string, 'b', 5): 16
strrpos($string, 'b', 15): 16
strrpos($string, 'b', 19):
strrpos($string, 'b', -5): 3
strrpos($string, 'b', -15): 3
This does not make sense.

Description:
------------
The offset parameter of the strrpos function is the offset from the end
of the string. The documentation is unclear about this:
"As of PHP 5.0.0 offset may be specified to begin searching an
arbitrary number of characters into the string."
I would expect it to start at $string+$offset, searching backwards.
Reproduce code:
---------------
<?php
echo "strrpos with offset\n";
$string='abcdefghijklmnopqrstuvwxyz';
echo "string: $string\n";
echo 'strrpos($string, \'n\', 5): '.strrpos($string, 'n', 5)."\n";
echo 'strrpos($string, \'n\', 15): '.strrpos($string, 'n', 15)."\n";
echo 'strrpos($string, \'n\', -5): '.strrpos($string, 'n', -5)."\n";
echo 'strrpos($string, \'n\', -15): '.strrpos($string, 'n',
-15)."\n";
?>
Actual result:
--------------
strrpos with offset
string: abcdefghijklmnopqrstuvwxyz
strrpos($string, 'n', 5): 13
strrpos($string, 'n', 15):
strrpos($string, 'n', -5): 13
strrpos($string, 'n', -15):
