推荐答案

如果您正在寻找PHP解决方案而不是javascript解决方案（潜在的重复项不提供），您可以使用GD的 getimagesize（）并查看它返回的内容。当提供的图像格式无效时，它将返回false并抛出错误。

If instead you are looking for a PHP solution instead of a javascript solution (which the potential duplicates do not provide), you can use GD's getimagesize() in PHP and see what it returns. It will return false and throw an error when the provided image format is not valid.
