php缩略图的问题
以下是我的代码：
1.2.https://www.gxlcms.com/$ef='index\images\m_1307414811439.jpg';
3.$bs="
";
4.$rr=getimagesize(https://www.gxlcms.com/$ef);
5.$new=imagecreatetruecolor(300,300);
6.imagecopyresized($new,$bs,0,0,0,0,300,300,$rr[0],$rr[1]);
7.header("content-type:image/jpeg");
8.imagejpeg($new);
9.?>
出现的问题是6,7行报错，还有乱码

------解决方案--------------------imagecopyresized函数的前两个参数要求是图形对象变量，不是文件名路径字符串之类的东西，你第2个参数传的是$bs，然而你前面把它赋值为字符串内容，所以出错
我随便修了下代码，你看着思考吧
https://www.gxlcms.com/$ef='1.jpg';
$bs=imagecreatefromjpeg(https://www.gxlcms.com/$ef);
$rr=getimagesize(https://www.gxlcms.com/$ef);
$new=imagecreatetruecolor(300,300);
imagecopyresized($new,$bs,0,0,0,0,300,300,$rr[0],$rr[1]);
header("content-type:image/jpeg");
imagejpeg($new);
