$ id不与链接一起使用

Question

I am creating a hyperlink in foreach loop. It is working fine. When I am passing $id in URL parameter then it is not working. my link is showing http://****/test/index.php/test/view?id=**. i don't what i am doing wrong here.

    foreach($list as $item)
    {
         $rs[]=$item['uname'];
         $id=$item['uid'];
         //var_dump($id); here it's printing $id value...
         echo '<b> <a href="/test/index.php/test/view?id="'.$id.'">'.$item['uname'].'</a><br/>';
    }    

I want to pass $id value with hyperlink. Please suggest me.

It's of course getting printed -- your browser is just not displaying it to you since it's not being correctly parsed as HTML due to the extra " around the $id variable.

Set your header as follows:

header('Content-Type: text/plain');

and you'll see that it returns something like:

<b> <a href="/test/index.php/test/view?id="55">FOOBAR</a><br/>
            ^                             ?  ^

As you can see, the issue is the extra double-quote before 55.

Change your code to:

echo '<b> <a href="/test/index.php/test/view?id=' . $id .'">'. 
$item['uname'] . '</a><br/>';

Alternatively, you could also use double-quotes and enclose your variables inside {}, like so:

echo "<b> <a href=\"/test/index.php/test/view?id=$id\">{$item['uname']}
</a><br/>";

I'd use sprintf as it's cleaner.

echo sprintf('<b> <a href="%u">%s</a><br/>', $id, $item['uname']);
