怎么取出百度某排行榜50条并在每条加前后缀呢

如http://top.baidu.com/buzz?b=26&c=1&fr=topcategory_c1

回复讨论(解决方案)

已把主要???集成??，加前後?你想怎?加都可以了。

?集后的??格式如下：

function getContent 修改?以下代?。

function getContent($url){	$ch = curl_init();	curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);		curl_setopt($ch, CURLOPT_URL, $url);	curl_setopt($ch, CURLOPT_TIMEOUT, 300);	$response = curl_exec($ch);	if($error=curl_error($ch)){		die($error);	}	curl_close($ch);	$content = iconv('GB2312','UTF8//IGNORE',$response);	return $content;}

已把主要???集成??，加前後?你想怎?加都可以了。

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

<a href="xxx.php?title=匆匆那年">匆匆那年</a><a href="xxx.php?title=匆匆那年">匆匆那年</a><a href="xxx.php?title=匆匆那年">匆匆那年</a><a href="xxx.php?title=匆匆那年">匆匆那年</a><a href="xxx.php?title=匆匆那年">匆匆那年</a>

??出的完整例子，你好好??下。
中?你想改什?，直接改就可以了。
