PHP 中htmlentities函数的使用
对于htmlentities这个函数我是这么理解的，由于直接输入一些字符，浏览器不认识，所以会出现乱码，所以要用这个函数把一些字符转换成浏览器能认识的实体。不知这么理解对不对。

我这里看到一个例子
echo htmlentities("Coffee at Cafè Francaise costs $2.25.");
说由于è这个字符浏览器不认识，所以直接输出的话，会是乱码，所以要用htmlentities来转换一下。

可问题是我试了一下echo "Coffee at Cafè Francaise costs $2.25."; 也能正确的输出那个è。
请问这是什么原因？那我们还需要htmlentities吗？

------解决方案--------------------
你教英国人说英语，显然就是班门弄斧了
但你教法国人说英语，却又是很平常的了

用的浏览器能认得“è”，那是他的母语。有的浏览器不认得“è”，你却又不能将它枪毙掉。怎么办呢？弄个世界语告诉他
