Description
int 
iconv_strpos ( string haystack, string needle [, int offset [, string charset]] )
      Returns the numeric position of the first occurrence of
      needle in haystack.
    
      The optional offset parameter specifies
      the position from which the search should be performed.
    
      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.  | 
      If haystack or needle is
      not a string, it is converted to a string and applied as the ordinal
      value of a character.
    
      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.
    
      If charset parameter is omitted,
      string are assumed to be encoded in
      iconv.internal_charset.

      and mb_strpos().
