mb_strrpos — Find position of last occurrence of a string in a string

Description

mb_strrpos ( string $haystack , string $needle [, int $offset = 0 [, string|null $encoding = null ]] ) : int|false

Performs a multibyte safe strrpos() 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

haystack

The string being checked, for the last occurrence of needle

needle

The string to find in haystack.

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.
encoding

The encoding parameter is the character encoding. If it is omitted or null, 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.

Notes

Note: 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.

Changelog

Version Description
8.0.0 encoding is nullable now.
