PHP获取图片大小函数。  getimagesize() 能够得到图片及flash（swf）的大小。
语法




list($width, $height, $type, $attr) = getimagesize("image_name.jpg");



下面是一个实例程序，将image_name.jpg改为您的图片地址






<?php
list($width, $height, $type, $attr) = getimagesize(&quot;image_name.jpg&quot;);
echo &quot;Image width &quot; .$width;
echo &quot;<BR>&quot;;
echo &quot;Image height &quot; .$height;
echo &quot;<BR>&quot;;
echo &quot;Image type &quot; .$type;
echo &quot;<BR>&quot;;
echo &quot;Attribute &quot; .$attr;
?>
运行这个脚本，你会看到如下结果：


Image width 379

Image height 344

Image type 2

Image attribute width=&quot;379&quot; height=&quot;344&quot;



你能够轻易的得到图片的宽度，高度及类型。
