readfile

(PHP 4, PHP 5)

readfile — Outputs a file

Description

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

Du kan använda en URL som filnamn till den här funktionen om direktivet fopen wrappers är påslaget. Se fopen() för fler detaljer kring hur du specificerar filnamnet och för en List of Supported Protocols/Wrapperslista över stödda URL-protkoll.

Note: Context support was added with PHP 5.0.0. For a description of contexts, refer to Streams.
