好吧,我有这样的代码,裁剪图像,并显示它,我想要做的是,而不是仅仅显示它,我想将图像保存在此文件夹中是完整的代码如何把图像放入目录imagejpeg()?

list($source_width, $source_height, $source_type) = getimagesize($source_path);

imagecopy(

header('Content-type: image/jpeg');
imagejpeg($desired_gdim);
/*

?>
我的问题是在最后一行,其中imagejpeg($desired_gdim);
应该imagejpeg($desired_gdim, 'img/whatever-filename.jpg');
但图像没有在浏览器甚至表示,它不会被发送到该目录,另外,如果我想与我已使用相同的上传它的文件名中插入它事情发生只是一个破碎的图像的小图标
header(content-type:image/jpeg),你想要显示图片,只需使用'imagejpeg($ desired_gdim $ filename)' – 2013-03-11 08:01:14
定义“不工作”。发生了什么或没有发生什么?你有任何错误?你检查过了吗? – deceze 2013-03-11 08:01:18
删除标题(内容类型),它用于渲染不保存。 Regards – 2013-03-11 08:02:04
