以下是OpenX服务器代码(Smarty插件)的一部分。 调用fopen时,将成功创建文件。但是fwrite不会在文件中写入任何数据并返回0(不是FALSE)。
文件夹本身具有以下权限: drwxrwxrwx没人没人
使用以下权限创建文件: -rw-r - r--没人没人
这是代码。
function smarty_core_write_file($params, &$smarty)
{
$_dirname = dirname($params['filename']);
if ($params['create_dirs']) {
$_params = array('dir' => $_dirname);
require_once(SMARTY_CORE_DIR . 'core.create_dir_structure.php');
smarty_core_create_dir_structure($_params, $smarty);
}
// 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);
if (DIRECTORY_SEPARATOR == '\\' || !rename($_tmp_file, $params['filename'])) {
// On platforms and filesystems that cannot overwrite with rename()
// delete the file before renaming it -- because windows always suffers
// this, it is short-circuited to avoid the initial rename() attempt
unlink($params['filename']);
rename($_tmp_file, $params['filename']);
}
chmod($params['filename'], $smarty->_file_perms);
return true;
}
以下是我用来测试此功能的代码:
$params = array('filename'=>'/usr/apache/www/templates_compiled/%%72^729^729250E1%%main.html.php', 'contents'=>'testString', 'create_dirs'=>TRUE);
smarty_core_write_file($params, NULL);
答案 0 :(得分:1)
问题是服务器已满。因此,在释放一些空间后,代码运行良好。
