MB_STRRPOS(3) 1 MB_STRRPOS(3)mb_strrpos - Find position of last occurrence of a string in a stringSYNOPSIS
int mb_strrpos (string $haystack, string $needle, [int $offset], [string $encoding = mb_internal_encoding()])
DESCRIPTION
Performs a multibyte safe strrpos(3) operation based on the number of characters. $needle position is counted from the beginning of
$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
-The $encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used.
RETURN VALUES
Returns the numeric position of the last occurrence of $needle in the $haystack string. If $needle is not found, it returns FALSE.

The $encoding parameter was moved from the third position to the fourth in PHP 5.2.0. For backward compatibility, $encoding can be
specified as the third parameter, but doing so is deprecated and will be removed in the future.
