PHP关于GetImageSize 判断网络图片类型问题

本帖最后由 ciscole 于 2013-09-02 14:39:26 编辑
$data = GetImageSize($logoUrl); <br />
<br />
if $data[2] =='1' {<br />
	$logo = ImageCreateFromGIF($logoUrl); <br />
}<br />
<br />
else if $data[2] =='2' {<br />
	$logo = ImageCreateFromJPEG($logoUrl); <br />
} <br />
else {<br />
	$logo = ImageCreateFromPNG($logoUrl); <br />
}


我这样写有错吗?那应该如何写!才学php 两天
我的要解决的问题是这样的:
就是一个图片的URL,这个图片URL 格式大致是这样的http://www.x.com/logo.php?XXXXXX (无扩展名)
这个图片可能是jpg,也可能是gif,也可能是png
我该怎么做!
