Description
array 
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.
