PHP图像维度

Question

如何获得图像的宽度和高度？

我有 $variable = 'http://site.com/image.png"

想将此图像的宽度 $width 和高度 $height.

像：$variable = 'http://site.com/image.png"

$width = '300'; // image width is 300px
$height = '500'; // height is 500px

谢谢。

$variable = 'http://site.com/image.png';
$image    = getimagesize($variable);
$width    = $image[0];
$height   = $image[1];
$type     = $image[2];
