iconv_strrpos

Finds the last occurrence of a needle within a haystack

&reftitle.description; ``int``false```iconv_strrpos` `string` `haystack` `string` `needle` ``string``null```encoding`&null;

Finds the last occurrence of a `needle` within a `haystack`.

In contrast to `strrpos`, 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 `encoding`.

&reftitle.parameters;

`haystack`

- The entire string.

`needle`

- The searched substring.

`encoding`

- If `encoding` parameter is omitted or &null;, `string` are assumed to be encoded in iconv.internal_encoding.

If `haystack` or `needle` is not a string, it is converted to a string and applied as the ordinal value of a character.

&reftitle.returnvalues;

Returns the numeric position of the last occurrence of `needle` in `haystack`.

If `needle` is not found, `iconv_strrpos` will return &false;.
