iconv_strpos — Finds position of first occurrence of a needle within a haystack
$haystack
, string $needle
[, int $offset = 0
[, string $charset = ini_get("iconv.internal_encoding")
]] )
Finds position of first occurrence of a needle
within a haystack.
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.
haystack
The entire string.
needle
The searched substring.
offset
The optional offset parameter specifies
the position from which the search should be performed.
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.
Returns the numeric position of the first occurrence of
needle in haystack.
If needle is not found,
iconv_strpos() will return FALSE.
