——解决方案——————–
class Smarty_Internal_Write_File {
/**
* Writes file in a save way to disk
*
* @param string $_filepath complete filepath
* @param string $_contents file content
* @return boolean true
*/
public static function writeFile($_filepath, $_contents, $smarty)
搞代gaodaima码{
$old_umask = umask(0);
$_dirpath = dirname($_filepath); //$_filepath的路径
// if subdirs, create dir structure
if ($_dirpath !== ‘.’ && !file_exists($_dirpath)) {//路径（文件夹）不存在
mkdir($_dirpath, $smarty->_dir_perms, true);//创建
}
// write to tmp file, then move to overt file lock race condition
$_tmp_file = tempnam($_dirpath, ‘wrt’);//tempnam应该是转换路径到配置的模板转换保存目录，就是smarty模板文件转换成php代码文件的文件存放的位置
if (!($fd = @fopen($_tmp_file, ‘wb’))) {//检查目录是否可以操作
$_tmp_file = $_dirpath . DS . uniqid(‘wrt’);//转换文件名
if (!($fd = @fopen($_tmp_file, ‘wb’))) {
throw new SmartyException(“unable to write file {$_tmp_file}”);
return false;
}
}
fwrite($fd, $_contents);//写转换后的内容，就是把smarty代码转换成php代码，
fclose($fd);
// remove original file
if (file_exists($_filepath))
@unlink($_filepath);
// rename tmp file
rename($_tmp_file, $_filepath);
// set file permissions
chmod($_filepath, $smarty->_file_perms);
umask($old_umask);
return true;
}
}
