使用PHP或CSS调整图像大小?
基本上我有一个 div ，其中包含用户的照片.为了使照片完全充满div，我必须调整照片的大小.
Basically I have a div which contains a user's photo.
In order for the photo to fill the div completely, I must resize the photo.
- 问题是，我是编程的新手，我不确定哪种方法最适合调整图像的大小以适合div(我猜最可靠的方法是PHP).
我的问题是:我应该使用PHP函数来调整图像的大小，还是应该使用CSS设置指定的照片尺寸?(寻找最可靠的方法)
My question is: Should I resize the image using a PHP function, or should I be setting specified photo dimensions with CSS? (Looking for most robust method)
您可以看到StackOverflow如何做到的，只需在图像上设置宽度和高度即可.使用CSS进行描述时的想法...
You can see how StackOverflow does it, simply setting a width and height on the image. What you are thinking of when describing using CSS...

现在，该选项对于缩小尺寸非常有效，而对于图像放大尺寸则不太适用.让用户上传大小大于您将显示的最大大小的内容.否则，您将获得拉伸"的不良质量.
Now that works great for down-sizing, less so for image up-sizing. Get the user to upload something equal in size of larger than the maximum size you will display at. Otherwise you will get "stretched" poor quality.

Then of course aspect ratio is the other factor.
