不明白你的意思!

a.php 只是定义了一个函数,b.php 中并没有调用它

版主啊,求帮忙

不知道你想表达什么
如果你是想让b.php 这段代码 能在a.php里运行 ,那就加在

while ($rw=DB::fetch($rs)){        $array[]=$rw;    }
Copy after login
Copy after login
Copy after login

这段代码里,定义一个$array[‘tupian’] = (b.php 返回的值)

这样子,return $array 的时候,在html里,解析一下,就可以了

我想表达的是能不能用变量$tupian代替b.php,然后html里解析直接是来个高手啊,一个困扰我很久的php问题,求帮助,而不是来个高手啊,一个困扰我很久的php问题,求帮助。不知道可以吗

还有就是您说的这个代码具体怎么加,请贴一下代码,我php很初级,谢谢

dz好像有个标签,里面写$tupian = b.php?aid=$o[aid];不知道是不是你要问的
提问时最好表达简明准确,你的目的是什么,你碰到的问题是什么

谢了,大概就是你写的这个代码的意思,你的这个代码怎么加啊,
while ($rw=DB::fetch($rs)){
        $array[]=$rw;
 $tupian = b.php?aid=$o[aid];
   }
我这样加直接就报错了

我写的是语法不标准的示例,准确的是
$tupian = 'b.php?aid=' . $rw['aid'];
字符串要加引号
