下面的代码将确保所有上传的照片在上传时都能是正确定向:
<?php $image = imagecreatefromstring(file_get_contents($_FILES['image_upload']['tmp_name'])); $exif = exif_read_data($_FILES['image_upload']['tmp_name']); if(!empty($exif['Orientation'])) { switch($exif['Orientation']) { case 8: $image = imagerotate($image,90,0); break; case 3: $image = imagerotate($image,180,0); break; case 6: $image = imagerotate($image,-90,0); break; } } // $image now contains a resource with the image oriented correctly ?>
经测试,Android拍照的 Orientation 属性都是1,判断不出是否被旋转了。
