代码中数组赋值的地方,换成通过sql语句来做的话要怎么做?我是下边这样,但是测试输出的xml文件全都是hhh...什么的。
PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->$query = sql语句;$result = mysql_query($query);while($row = mysql_fetch_array($result)){    $data_array['loc']="http://zufang.sslook.com/sh/$ran/$row[0]";    $data_array['priority']='1.0';    $data_array['lastmod']='2012-12-12';    $data_array['changefreq']='weekly';    }
Copy after login



------解决方案--------------------
while($row = mysql_fetch_array($result))
{ $data_array['loc']="http://zufang.sslook.com/sh/$ran/$row[0]";
$data_array['priority']='1.0';
$data_array['lastmod']='2012-12-12';
$data_array['changefreq']='weekly';
}
这个while再次循环时,数组值data_array又被覆盖了,所以最终就一个值了,添加flag
改为以下,都是hhh什么意思,数据库里东西吗,发出来看一下
PHP code
$i= 0;while($row = mysql_fetch_array($result)){    $data_array[$i]['loc']="http://zufang.sslook.com/sh/$ran/$row[0]";    $data_array[$i]['priority']='1.0';    $data_array[$i]['lastmod']='2012-12-12';//这些都被你定死了    $data_array[$i]['changefreq']='weekly';    ++$i;    }<div class="clear">
                 
              
              
        
            </div>
