php - PHP Pull Image And Display

Question

I have a PHP file which I have used mod rewrite to make a .jpg extension. I want to grab an image from a url

example: http://msn.com/lol.gif

take the data and then display it in my .jpg with jpeg headers, so as far as the user is concerned it is a normal image. Is this possible and if so can anyone give me some pointers?

Answer 1

如果您结合使用 curl 和 PHP 的图像处理方法（您可以在此处了解） ，您将获得所需的内容。

Answer 2

使用 php GD 库：

header('Content-type: image/jpeg');
$pic = imagecreatefromgif($url);
Imagejpeg($pic);
ImageDestroy($pic);

使用 imagick 库：

header('Content-type: image/jpeg');
$image = new Imagick($url);
$image->setImageFormat( "jpg" );
echo $image;

Answer 3

根据您的需要（您需要处理图像吗？），您可以打开远程文件并将其输出到浏览器。
