iconv_strpos

(PHP 5)

iconv_strpos — Finds position of first occurrence of a needle within a haystackDescriptionint iconv_strpos ( string haystack, string needle [, int offset [, string charset]] )

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.

Parameters

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.

Return Values

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

If needle is not found,
iconv_strpos() will return FALSE.

Warning

This function may
return Boolean FALSE, but may also return a non-Boolean value which
evaluates to FALSE, such as 0 or
“”. Please read the section on Booleans for more
information. Use the ===
operator for testing the return value of this
function.
