iconv_strrpos

(PHP 5)

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

Description

int 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.

警示

本函數可能返回布林值 FALSE,但也可能返回一個與 FALSE 等值的非布林值,例如 0 或是 ""。請參閱布爾類型章節以取得更多訊息。應使用 === 運算符來測試本函數的返回值。

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.
