>&#13;   Using streams is very much like using ANSI stdio functions.  The main
   difference is in how you obtain the stream handle to begin with.
   In most cases, you will use <B
CLASS="function"
>php_stream_open_wrapper()</B
>
   to obtain the stream handle.  This function works very much like fopen,
   as can be seen from the example below:
