当PHP被禁用的PHP函数:tempnam()后

当PHP被禁用的PHP函数:tempnam() 后,tempnam()可建立一个临时档,档名不会与同目录中的档案重覆。

  传回字串就是建立的临时档名。若发生错误则传回空字串。

  而smarty运行就必须在类似templates_c的设置编译目录,然后运行后它会自动创建类似%%

  43^43B^43B32F4B%%index.htm.php的临时档,所以,tempnam()被禁用后,当然不能自动创建类似%%

  43^43B^43B32F4B%%index.htm.php的临时档,自然自动创建类似%%
  43^43B^43B32F4B%%index.htm.php的临时档,是一片空白.

  smarty中使用tempnam函数的程序是internals/core.write_file.php,如下代码:

PHP代码:-----------------------------------------------------------------------
// write to tmp file, then rename it to avoid
// file locking race condition
$_tmp_file = tempnam($_dirname, 'wrt');
if (!($fd = @fopen($_tmp_file, 'wb'))) {
$_tmp_file = $_dirname . DIRECTORY_SEPARATOR . uniqid('wrt');
if (!($fd = @fopen($_tmp_file, 'wb'))) {
$smarty->trigger_error("problem writing temporary file '$_tmp_file'");
return false;
}
}
fwrite($fd, $params['contents']);
fclose($fd);
