SYNOPSIS
int mb_strrpos (string $haystack, string $needle, [int $offset], [string $encoding = mb_internal_encoding()])

$haystack. First character's position is 0. Second character position is 1.
PARAMETERS
o $haystack
- The string being checked, for the last occurrence of $needle
o $needle
- The string to find in $haystack.
o $offset
- May be specified to begin searching an arbitrary number of characters into the string. Negative values will stop searching at an
arbitrary point prior to the end of the string.
o $encoding
