# iconv_strrpos

(PHP 5)

iconv_strrpos -- Finds the last occurrence of a needle within the specified range of haystack

## Description

string iconv_strrpos ( string haystack, string needle [, string charset] )

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

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

警告
本函数可能返回布尔值 `FALSE`，但也可能返回一个与 `FALSE` 等值的非布尔值，例如 0 或者 ""。请参阅布尔类型章节以获取更多信息。应使用 === 运算符来测试本函数的返回值。

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.
