Streams and Filters

Now we have implemented our very own file stream. The script that uses it might look like this:


<?php
$fp = example_open("/path/to/file");
fwrite($fp, "hello there\n");
rewind($fp);
echo fgets($fp);
?>

Outputs:

hello there

Key points:

• Custom opener function.

• Returned stream works with fread(), fwrite() etc.

• Not covered cast, fstat and option interface.
