function getContent 修改?以下代?。

为什么我测试时，这个数组输出的是空的 你的php文件是否utf8
你的php文件是否utf8
是的 那你先把getContent的返回?出，看看有什?。
?了，你把????打?，如果白屏估?是??。你是否有安?curl?
在?面?加上
ini_set('display_errors','on');
error_reporting(E_ALL);
看看有什??。如果提示curl?有安?的，
可以改getContent?
function getContent($url){ $response = file_get_contents($url); // ?句代替curl $content = iconv('GB2312','UTF8//IGNORE',$response); return $content;} 什么都没输出
编码换成ANSI也不成
你测试可用的文件能打包的吗
Notice: iconv() [function.iconv]: Wrong charset, conversion from `GB2312' to `UTF8//IGNORE' is not allowed in F:\PHPnow-1.5.6\vhosts\test.php on line 15
$content = iconv('GB2312','UTF-8',$response);
这样就成了
问题我是个菜鸟，这个数组要怎么取出来正常使用呢 $content = iconv('GBK','UTF-8//IGNORE', $response);
Notice: iconv() [function.iconv]: Wrong charset, conversion from `GB2312' to `UTF8//IGNORE' is not allowed in F:\PHPnow-1.5.6\vhosts\test.php on line 15
$content = iconv('GB2312','UTF8//IGNORE',$response);
改?
$content = iconv('GBK','UTF8//IGNORE',$response);
??
拿到???不知道怎?用。。。呵呵。
你想?示的?子是怎?的，就做成怎?的html，然後在需要的地方，插入????。
数组一巧不同，郁闷了
其实我只要成这样就行的
匆匆那年匆匆那年匆匆那年匆匆那年匆匆那年
??出的完整例子，你好好??下。
中?你想改什?，直接改就可以了。

baidu
=$i ?> =$val['name'] ?> ?介 新? ?吧
=$val['num'] ?>
