strrpos

(PHP 3, PHP 4 >= 4.0.0)

strrpos --  Find position of last occurrence of a char in a string

Description

int strrpos ( string haystack, char needle)

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.

Note: It is easy to mistake the return values for "character found at position 0" and "character not found". Here's how to detect the difference:

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