(PHP 5 CVS only)iconv_strrpos -- Finds the last occurrence of a needle within the specified range of haystack.
Returns the numeric position of the last occurrence of needle in haystack.
If needle is not found, iconv_strrpos() will return FALSE.
This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE, such as 0 or "". Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.
If haystack or needle is not a string, it is converted to a string and applied as the ordinal value of a character.
In contrast to strpos(), the return value of iconv_strrpos() is the number of characters that appear before the needle, rather than the offset in bytes to the position where the needle has been found. The characters are counted on the basis of the specified character set charset.
