使用PHP输出为图像 [英] Output as an image using PHP

问题描述

我正在为"CMS"创建评论系统，并希望实现头像.我希望有一个"GETavatar.php"，它使用GET请求为特定用户查找图像，同时还要进行一些图像处理.

I'm creating a comments system for my 'CMS' and would like to implement avatars. I would like to have a "getavatar.php" that uses a GET request to find an image for a certain user, while also doing some image processing.

有人能指出我正确的方向，以便从php脚本中将数据输出为"image/png"吗?

Could anybody point me in the right direction for outputting data as "image/png" from a php script?

例如，以生成300x300的方式 http://placehold.it/300x300 网址中提供的参数中的png图片.

An example of this would be http://placehold.it/300x300 in the way it generates a 300x300 png image from the parameters given in the URL.
