(PHP 4, PHP 5)
readfile — Outputs a file
Reads a file and writes it to the output buffer.
The filename being read.
You can use the optional second parameter and set it to TRUE, if you want to search for the file in the include_path, too.
A context stream resource.
Returns the number of bytes read from the file. If an error occurs, FALSE is returned and unless the function was called as @readfile(), an error message is printed.
You can use a URL as a filename with this function if the fopen wrappers have been enabled. See fopen() for more details on how to specify the filename and List of Supported Protocols/Wrappers for a list of supported URL protocols.
Note: Context support was added with PHP 5.0.0. For a description of contexts, refer to Streams.
