     Methods

    Constructor

    __construct() 

    Excel limits the size of BIFF records.

    _addContinue(string $data) : string

    In Excel 5 the limit is 2084 bytes. In Excel 97 the limit is 8228 bytes. Records that are longer than these limits must be split up into CONTINUE blocks.

    This function takes a long BIFF record and inserts CONTINUE records as necessary.

    access private

    Parameters

    $data

    string

    The original binary data to be written

    Returns

    stringA very convenient string of continue blocks

    General storage function

    _append(string $data) 
    access private

    Parameters

    $data

    string

    binary data to append

    Writes Excel BOF record to indicate the beginning of a stream or sub-stream in the BIFF file.

    _storeBof(integer $type) 
    access private

    Parameters

    $type

    integer

    Type of BIFF file to write: 0x0005 Workbook, 0x0010 Worksheet.

    Writes Excel EOF record to indicate the end of a BIFF stream.

    _storeEof() 
    access private

    Determine the byte order and store it as class data to avoid recalculating it for each call to new().

    getByteOrder() : int
    Static

    Returns

    int

    General storage function like _append, but returns string instead of modifying $this->_data

    writeData(string $data) : string

    Parameters

    $data

    string

    binary data to write

    Returns

    string

    Writes Excel EOF record to indicate the end of a BIFF stream.

    writeEof() 
    access private

     Properties

     

    $_data : string
     

    $_datasize : integer

    Should be the same as strlen($this->_data)

     

    $_limit : integer

    See _addContinue()

    see \_addContinue()
     

    $_byte_order : integer

    0 => little endian, 1 => big endian
