說明
int iconv_strrpos ( string$haystack
, string $needle
[, string $charset = ini_get("iconv.internal_encoding")
] )
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 charset.
參數
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.
返回值
Returns the numeric position of the last occurrence of
needle in haystack.
If needle is not found,
iconv_strrpos() will return FALSE.
此函數可能返回布爾值
