iconv_strrpos

(PHP 5, PHP 7)

Finds the last occurrence of a needle within a haystack

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.

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.

Returns:

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

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. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.
