(PHP 5)

iconv_strrpos — Finds the last occurrence of a needle within a haystack

### Description

int iconv_strrpos ( string `$haystack` , string `$needle` [, string `$charset` = ini_set("iconv.internal_encoding") ] )

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.

### Parameters

`haystack`

  The entire string.

`needle`

  The searched substring.

`charset`

  If `charset` parameter is omitted, `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.

### Return Values

Returns the numeric position of the last occurrence of `needle` in `haystack`. The characters are counted on the basis of the specified character set `charset`.

If `needle` is not found, iconv_strrpos() will return `FALSE`.

Warning

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.
