Get image dimensions
提问by James
I have an url to the image, like $var = http://example.com/image.png
我有一个图片的网址，比如 $var = http://example.com/image.png
How do I get its dimensions to an array, likearray([h]=> 200, [w]=>100)(height=200, width=100)?
我如何将它的维度设置为一个数组，比如array([h]=> 200, [w]=>100)(height=200, width=100)？

You can use the getimagesizefunction like this:
您可以getimagesize像这样使用该函数：
list($width, $height) = getimagesize('path to image');
echo "width: " . $width . "<br />";
echo "height: " . $height;

Using getimagesizefunction, we can also get these properties of that specific image-
使用getimagesize函数，我们还可以获取该特定图像的这些属性-
<?php
list($width, $height, $type, $attr) = getimagesize("image_name.jpg");
echo "Width: " .$width. "<br />";
echo "Height: " .$height. "<br />";
echo "Type: " .$type. "<br />";
echo "Attribute: " .$attr. "<br />";
//Using array
$arr = array('h' => $height, 'w' => $width, 't' => $type, 'a' => $attr);
?>
Result like this -
结果是这样的——
Width: 200
Height: 100
Type: 2
Attribute: width='200' height='100'
宽度：200
高度：100
类型：2
属性：width='200' height='100'
Type of image consider like -
图像类型考虑如下 -
1 = GIF
2 = JPG
3 = PNG
4 = SWF
5 = PSD
6 = BMP
7 = TIFF(intel byte order)
8 = TIFF(motorola byte order)
9 = JPC
10 = JP2
11 = JPX
12 = JB2
13 = SWC
14 = IFF
15 = WBMP
16 = XBM
1 = GIF
2 = JPG
3 = PNG
4 = SWF
5 = PSD
6 = BMP
7 = TIFF（英特尔字节顺序）
8 = TIFF（摩托罗拉字节顺序）
9 = JPC
10 = JP2
11 = JPX
12 = JB2
13 = SWC
14 = IFF
15 = WBMP
16 = XBM
