我试着让iphone图片在调整大小时旋转，但我似乎不能让它工作。
上传和调整大小部分工作正常。旋转部分给我带来了麻烦。
我希望有人能发现我的新手错误!: -)function image_fix_orientation($src, $filename) {

编辑:我尝试了解决方案张贴在答案，但现在我得到这个错误:https://gyazo.com/591feaa396e194a69a012715d02a32e7
提前感谢您的宝贵时间!
致以最亲切的问候!: -)
imagerotate()正在等待一个图像资源，您正在为它提供一个文件路径字符串。
将呼叫移到imagecreatefromjpeg()函数之后的image_fix_orientation()
if($extension=="jpg" || $extension=="jpeg" ) {
$uploadedfile = $_FILES[$inputImage]['tmp_name'];
$src = imagecreatefromjpeg($uploadedfile);
$src = image_fix_orientation($src , $filename);
}
