你在一个页面中输出了两种类型的数据,浏览器不知道怎么把他们分开。于是就 乱码了
你需要将
$wea = "http://1.alilo.sinaapp.com/Weather/0.jpeg";
$weai = imagecreatefromgif($wea);
header("Content-type:image/jpeg");
imagejpeg($weai);
改为
echo '';
如果你确实想通过抓取图片的方式了完成,那么需要将那4行单独写成文件,比如 wea.php
然后通过标记
去调用

你不都是
$img = imagecreatefromgif($path);
header("Content-type:image/gif");
imagegif($img);
这样的吗?
一样的问题就不会举一反三吗?
