需要 PHP 图像调整器/裁剪脚本
我正在抓取图像链接，需要将其即时转换为 72x108 以在网站上显示。源图像来自各种分辨率，因此需要裁剪。
我知道 PHP 的中等水平，所以我可能可以做一些满足我需要的东西，但希望有一些可以通过 url 请求调用的东西。 EG：mysite.com/thumbnail.php?src=http://anothersite.com/image.jpg&w=72&h=108
这将是理想的，它需要支持jpg/png。
提前致谢！
I am grabbing links to images and need to convert them on the fly to 72x108 to display on a website. The source images come from various resolutions, so cropping is required.
I know a moderate level of PHP so I can probably make something work for my needs, but was hoping for something that could be called by a url request. EG: mysite.com/thumbnail.php?src=http://anothersite.com/image.jpg&w=72&h=108
That would be ideal, it needs to support jpg/png.
Thanks in advance!

这是一个非常方便的脚本，用于处理和上传图像，它永远是谷歌搜索结果的顶部。我几年前就用过它，它非常容易实现。看起来它也是几周前才更新的:)

这可能有点过分了，但是如果您查看示例，您会发现可以用它做很多事情。如果您不在本项目中使用它，那么在下一个项目中尝试一下可能是值得的。
Here is a really handy script for processing and uploading images that's been a top google result for forever. I used it years ago and it was really easy to implement. Looks like it was just updated a couple weeks ago too :)

This may be overkill, but if you check out the examples you can see there's a lot you can do with it. If you don't use it for this project, it might be worthwhile to try out for the next one.
只需使用 file_get_contents 或使用 curl 从 url 读取图像，然后使用 php gd 库根据您的需要调整图像大小和裁剪图像。
请访问以下链接以获取更多信息：

just read the image from the url with file_get_contents or using curl and use the php gd library to resize and crop the image as per your needs.
