iconv_strpos — Finds position of first occurrence of a needle within a haystack

The entire string.

The optional offset parameter specifies the position from which the search should be performed.
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.
Returns the numeric position of the first occurrence of needle in haystack .
If needle is not found, iconv_strpos() will return FALSE.
