我想通过PHP来实现查询
比如http://127.0.0.1/1.php?city=北京 就能找到对应的101010100
不会PHP 只好来求助,麻烦大虾给段详细的代码!

------解决方案--------------------

//随便写了下,注意data.txt为gb2312编码
PHP code


$city=$_REQUEST["city"];
$city=iconv("utf-8","gb2312",$city);
if ($city)
{
    $fp=fopen("data.txt","r");
    while (!feof($fp))
    {
        $buffer = fgets($fp);
        list($code,$area)=explode("=",$buffer);


        if (trim($area)==$city)
        {
            echo $code;
        }

    }
    fclose($fp);

}
?>

echo urldecode("%E5%8C%97%E4%BA%AC");
输出 :北京

记得txt文件与你的php文件编码要统一,否则会乱码,或者要转化一下也可。

我直接用2楼的那个代码,没有任何输出,原因是查询时 汉字没有urlencode

我不知道怎么加,PHP完全不懂!
