有一个画图的函数，是别人写的，叫photo.php。代码应该是没有问题的。因为之前已经测试成功了。是可以画图的。不管有没有参数，都可以输出一个图。（没有参数输出的是一个图上面写“没有参数”）现在 我在自己的PHP里面引用这个脚本。但是输出的是一个叉。我引用时候写的代码如下所示：if($SelectType == "photo")
{
echo "<img src='photo.php?AirPortID1=$AirPortID1&AirPortID2=$AirPortID2&AirPortID3=$AirPortID3&AirPortID4=$AirPortID4&AirPortID5=$AirPortID5&Elevation=$Elevation' >";}后面那一串都是参数。这个画图的函数，咱们不管怎么画的，不管他的逻辑
他最后是这么写的//设定文件头
header('Content-type: image/png');
//输出图像
imagepng($img);
//释放资源
imagedestroy($img);
这个释放资源，有问题吗？请问这是怎么回事？？
为什么会输出一个叉，而不是一个图呢？
{
echo "<img src='photo.php?AirPortID1=$AirPortID1&AirPortID2=$AirPortID2&AirPortID3=$AirPortID3&AirPortID4=$AirPortID4&AirPortID5=$AirPortID5&Elevation=$Elevation' >";}后面那一串都是参数。这个画图的函数，咱们不管怎么画的，不管他的逻辑
他最后是这么写的//设定文件头
header('Content-type: image/png');
//输出图像
imagepng($img);
//释放资源
imagedestroy($img);

if($SelectType == "photo")
{
echo "<img src='http://****/photo.php?AirPortID1=$AirPortID1&AirPortID2=$AirPortID2&AirPortID3=$AirPortID3&AirPortID4=$AirPortID4&AirPortID5=$AirPortID5&Elevation=$Elevation' >";}
参数对不对？？
主要是这两个
直接在浏览器里运行：
photo.php?AirPortID1=$AirPortID1&AirPortID2=$AirPortID2&AirPortID3=$AirPortID3&AirPortID4=$AirPortID4&AirPortID5=$AirPortID5&Elevation=$Elevation
还不行那就得看photo.php源码了。
copy的方法也试过了，还是看不了。我有源码。贴出来，麻烦您给看看？
谢谢了！！！
