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.
提示: 如果fopen wrappers已啟動,則可藉此函數把檔名當成URL使用。 參考fopen()有更多關於如何指定檔名的細節 和附錄 I支援URL協定的列表。
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.

file(), fopen(),
include(), require(), virtual()
