readfile

Outputs a file (PHP 4, PHP 5)
int readfile ( string filename [, bool use_include_path [, resource context]] )

Reads a file and writes it to the output buffer.

Parameters

filename

The filename being read.

use_include_path

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.

context

A context stream resource.

Return Values

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.

Notes

Tip:

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 Appendix O, 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.
