<code>
<?php

class weather
{
 var $weather=array("","","","","");

 function weather()
 {
 $fcont=@file_get_contents("http://www.tq121.com.cn/forecast/cf.php");
 $data=explode("", $fcont);
 $fdate=substr($data[1],2,18);
 $city=explode("461,292,498,308", $fcont);
 $fcast=$city[1];
 $fcastarr=explode(" ", $fcast);
 $wea[0]=chop(substr($fcastarr[0],-5,5));
 $wea[1]=chop(substr(trim($fcastarr[1]),5));
 $wea[2]=chop(substr(trim($fcastarr[2]),5));
 $wea[3]=chop(substr(trim($fcastarr[3]),5));
 $wea[4]=chop(substr(trim($fcastarr[4]),5));
 $this->$weather[0]=$wea[0];
 $this->$weather[1]=$wea[1];

 }

}
?>

<?PHP
$kkk=new weather;
print $kkk->$weather[0];
</code>

$weather[0]应该是"上海"
$weather[1]应该是天气情况.
为什么输入的情况却是.$weather[0]和weather[1]相同呢.
