PHP中的自动图像格式检测 [英] Automatic image format detection in PHP

问题描述

我正在寻找一种方法来获取用户上传的图像，该图像目前放置在一个临时位置，如：/ tmp / jkhjkh78，并从中创建一个php图像，自动检测格式。

有没有更聪明的方法来做这个比试图抓取imagefromjpeg，imagefrompng等？ 解决方案

这是 getimagesize 的功能之一。他们可能应该把它叫做getimageinfo，但这是你的PHP。

I am looking for a way to take a user uploaded image that is currently put in a temporary location ex: /tmp/jkhjkh78 and create a php image from it, autodetecting the format.

Is there a more clever way to do this than a bunch of try/catching with imagefromjpeg, imagefrompng, etc?

解决方案

This is one of the functions of getimagesize. They probably should have called it "getimageinfo", but that's PHP for you.
