 str_split    (PHP 5 CVS only) str_split -- 
     Convert a string to an array
    Descriptionarray str_split  ( string string [, int split_length]) 
     Converts a string to an array. If the optional
     split_length parameter is specified, the
     returned array will be broken down into chunks with each being
     split_length in length, otherwise each chunk
     will be one character in length.
     
     FALSE is returned if split_length is less
     than 1.  If the split_length length exceeds the
     length of string, the entire string is returned
     as the first (and only) array element.
