utf-8也只是ascii的一种。后来中手册上找到了个，把他改为了批量转换，还增加了一个常用的ascii代码还原字符。找可以把中文转ascii码的php代码，原作者是qh663
我在一个获取到的xml中提取数据，然而得到的数据是这样的
$string = '半自動波';
这样编码的字符在浏览器中能正常显示，但是直接存取这些数据却是乱码
只好转换一下，找来找去还是找回喜悦村，^_^
header("Content-Type: text/html; charset=UTF-8");
$string = '半自動波';
echo ascii::decode($string);
可以实现多种语言转换为ASCII,也可以实现ASCII convert utf-8
