 * </p>
 * @param type int[optional] <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.
 * </p>
 * @param use_include_path bool[optional] <p>
 * The optional third use_include_path parameter
 * can be set to '1' or true if you want to search for the file in the

 * The streams listed in the read array will be watched to
 * see if characters become available for reading (more precisely, to see if

 * </p>
 * @param except array <p>
 * The streams listed in the except array will be
 * watched for high priority exceptional ("out-of-band") data arriving.
 * </p>
 * <p>
 * When stream_select returns, the arrays
 * read, write and
 * except are modified to indicate which stream
 * resource(s) actually changed status.
 * </p>
 * You do not need to pass every array to
 * stream_select. You can leave it out and use an
 * empty array or &null; instead. Also do not forget that those arrays are
 * passed by reference and will be modified after
 * stream_select returns.
 * @param tv_sec int <p>
 * The tv_sec and tv_usec
 * together form the timeout parameter,
 * tv_sec specifies the number of seconds while
 * tv_usec the number of microseconds.
 * The timeout is an upper bound on the amount of time
 * that stream_select will wait before it returns.
 * If tv_sec and tv_usec are
 * both set to 0, stream_select will
 * not wait for data - instead it will return immediately, indicating the
 * current status of the streams.
 * </p>
 * <p>
 * If tv_sec is &null; stream_select
 * can block indefinitely, returning only when an event on one of the
 * watched streams occurs (or if a signal interrupts the system call).
 * </p>
 * <p>
 * Using a timeout value of 0 allows you to
 * instantaneously poll the status of the streams, however, it is NOT a
 * good idea to use a 0 timeout value in a loop as it
 * will cause your script to consume too much CPU time.
 * </p>
 * <p>
 * It is much better to specify a timeout value of a few seconds, although
 * if you need to be checking and running other code concurrently, using a
 * timeout value of at least 200000 microseconds will
 * help reduce the CPU usage of your script.
 * </p>

 * To implement a filter, you need to define a class as an extension of

 * as defined below. When performing read/write operations on the stream
 * to which your filter is attached, PHP will pass the data through your
 * filter (and any other filters attached to that stream) so that the
 * data may be modified as desired. You must implement the methods
 * exactly as described below - doing otherwise will lead to undefined
 * behaviour.
 * </p>
 * intfilter
 * resourcein
 * resourceout
 * intconsumed
 * boolclosing
 * <p>
 * This method is called whenever data is read from or written to
 * the attached stream (such as with fread or fwrite).
 * in is a resource pointing to a bucket brigade
 * which contains one or more bucket objects containing data to be filtered.
 * out is a resource pointing to a second bucket brigade
 * into which your modified buckets should be placed.
 * consumed, which must always
 * be declared by reference, should be incremented by the length of the data
 * which your filter reads in and alters. In most cases this means you will
 * increment consumed by $bucket->datalen
 * for each $bucket. If the stream is in the process of closing
 * (and therefore this is the last pass through the filterchain),
 * the closing parameter will be set to true.
 * The filter method must return one of
 * three values upon completion.
 * <tr valign="top">

 * <td>PSFS_ERR_FATAL (default)</td>
 * <td>
 * The filter experienced an unrecoverable error and cannot continue.
 * </td>
 * </tr>
 * </p>
 * boolonCreate
 * This method is called during instantiation of the filter class
 * object. If your filter allocates or initializes any other resources
 * (such as a buffer), this is the place to do it. Your implementation of
 * this method should return false on failure, or true on success.
 * When your filter is first instantiated, and
 * yourfilter-&gt;onCreate() is called, a number of properties
 * will be available as shown in the table below.
 * <p>
 * <tr valign="top">
 * <td>Property</td>
 * <td>Contents</td>
