 * </p>
 * <p>
 * Different operating system families have different line-ending
 * conventions. When you write a text file and want to insert a line
 * break, you need to use the correct line-ending character(s) for your
 * operating system. Unix based systems use \n as the
 * line ending character, Windows based systems use \r\n
 * as the line ending characters and Macintosh based systems use
 * \r as the line ending character.
 * </p>
 * <p>
 * If you use the wrong line ending characters when writing your files, you
 * might find that other applications that open those files will "look
 * funny".
 * </p>
 * <p>
 * Windows offers a text-mode translation flag ('t')
 * which will transparently translate \n to
 * \r\n when working with the file. In contrast, you
 * can also use 'b' to force binary mode, which will not
 * translate your data. To use these flags, specify either
 * 'b' or 't' as the last character
 * of the mode parameter.
 * </p>
 * <p>
 * The default translation mode depends on the SAPI and version of PHP that
 * you are using, so you are encouraged to always specify the appropriate
 * flag for portability reasons. You should use the 't'
 * mode if you are working with plain-text files and you use
 * \n to delimit your line endings in your script, but
 * expect your files to be readable with applications such as notepad. You
 * should use the 'b' in all other cases.
 * </p>
 * <p>
 * If you do not specify the 'b' flag when working with binary files, you
 * may experience strange problems with your data, including broken image
 * files and strange problems with \r\n characters.
 * </p>
 * <p>
 * For portability, it is strongly recommended that you always
 * use the 'b' flag when opening files with fopen.
 * </p>
 * <p>
 * Again, for portability, it is also strongly recommended that
 * you re-write code that uses or relies upon the 't'
 * mode so that it uses the correct line endings and
 * 'b' mode instead.
