(PHP 5)
iconv_strpos — Finds position of first occurrence of a needle within a haystack
Description
int iconv_strpos
( string $haystack
, string $needle
[, int $offset
[, string $charset
]] )
In contrast to strpos(), the return value of
iconv_strpos() 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
.

parameter specifies

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
Returns the numeric position of the first occurrence of
needle
in haystack
.
If needle
is not found,
iconv_strpos() will return FALSE.
