strrpos

Description

Returns the numeric position of the last occurrence of needle in the haystack string. Note that the needle in this case can only be a single character. If a string is passed as the needle, then only the first character of that string will be used.

If needle is not found, returns false.

If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.
