# readfile

(PHP 3, PHP 4 )

readfile -- Outputs a file

## Description

int readfile ( string filename [, int use_include_path])

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.

> 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 I for a list of supported URL protocols.

You can use the optional second parameter and set it to "1", if you want to search for the file in the include_path, too.

See also fpassthru(), file(), fopen(), include(), require(), virtual() and Appendix I.
