(PHP 4, PHP 5)
readfile — Outputs a file
Reads a file and writes it to the output buffer.
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.
A URL can be used 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 Stream Functions.
