做么会是 "No such file or directory"的？
其他 file 都放在同一个 directory.

<?
//Generate.php
$srcurl = "content.txt";
$tempfilename = "tempfile.php";
$targetname = "index.php";

@unlink($tempfilename);
$file = fopen($srcurl," ...

式下用full path name

PHP is "filename-case sensitive" language; and it will NOT get e.g. CONTENT.php as content.php, try to check whether the file exist, file wrong name, or not exist at all.

苦瓜汤

第一，filesize的argument type是String filename而不是resource;
第二，之前filesize的return是0，fread不允许.
第三，你需要directory的write permission.
