Finds the last occurrence of a needle within a haystack

Description

iconv_strrpos(string $haystack, string $needle, string|null $encoding = null): int|false

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 encoding.

Parameters

haystack

encoding

If encoding parameter is omitted or null, 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

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