stream_register_filter() allows you to implement your own filter on any registered stream used with all the other filesystem functions (such as fopen(), fread() etc.).	stream_register_filter() allows you to implement your own filter on any registered stream used with all the other filesystem functions (such as fopen(), fread() etc.).

class myfilter extends php_user_filter {function write($data) {$data = substr($data,1); $written_by_parent = parent::write($data); return ($written_by_parent + 1);}}	注意 If your filter alters the length of data, for example by removing the first character, before passing onto parent::write($data); it must be certain to include that stolen character in the return count.
The closing parameter tells you whether the stream is, in fact, in the process of closing.	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.
This method is called upon filter shutdown (typically, this is also during stream shutdown), and is executed after the flush method is called.	The example below implements a filter named rot13 on the foo-bar.txt stream which will perform ROT-13 encryption on all letter characters written to/read from that stream.

To implement a wrapper, you need to define a class with a number of member functions, as defined below.	(PHP 4 = 4.3.0)
You must implement the methods exactly as described below - doing otherwise will lead to undefined behaviour.	stream_register_wrapper() allows you to implement your own protocol handlers and streams for use with all the other filesystem functions (such as fopen(), fread() etc.).
If this flag is not set, you should not raise any errors.	stream_register_wrapper() will return FALSE if the protocol already has a handler.
If the requested resource was opened successfully, you should return TRUE, otherwise you should return FALSE	This method is called immediately after your stream object is created. path specifies the URL that was passed to fopen() and that this object is expected to retrieve. You can use parse_url() to break it apart.
You must release any resources that were locked or allocated by the stream.	mode is the mode used to open the file, as detailed for fopen(). You are responsible for checking that mode is valid for the path requested.
You must return up-to count bytes of data from the current read / write position as a string.	options holds additional flags set by the streams API. It can hold one or more of the following values OR'd together.
If no more data is available, return either FALSE or an empty string.	If the path is opened successfully, and STREAM_USE_PATH is set in options, you should set opened_path to the full path of the file/resource that was actually opened.
This method is called in response to fwrite() This method is called in response to fwrite() calls on the stream.	If the requested resource was opened successfully, you should return TRUE, otherwise you should return FALSE
If there is not enough room, try to store as many bytes as possible.	This method is called when the stream is closed, using fclose(). You must release any resources that were locked or allocated by the stream.
This method is called in response to fseek() This method is called in response to fseek() calls on the stream.	This method is called in response to feof() calls on the stream. You should return TRUE if the read/write position is at the end of the stream and if no more data is available to be read, or FALSE otherwise.
See fseek() for more information about these parameters.	This method is called in response to ftell() calls on the stream. You should return the current read/write position of the stream.
