SQL调用模板的错误之处

Question

while ($post = $db->fetch_array($lastquery)) {

if ($post['tag']) {

  $prefix = ' <div id="catt">#';
  $tag = explode( ',', $post['tag'] );
  $hashtag.=$prefix . implode( '</div>' . $prefix, $tag ) . '</div>';

  }

  else { $hashtag=""; }

$template .='  <div> '.$hashtag.'  </div>  ';

}

This sends something like this:

-1 Post number one hashtags: {$numbers1}

-2 Post number two hashtags: {$numbers1}{$numbers2}

-3 Post number three hashtags: {$numbers1}{$numbers2}{$numbers3}

and thats the same for all. how can I stop this like this:

-1 Post number one hashtags: {$numbers1}

-2 Post number two hashtags: {$numbers2}

-3 Post number three hashtags: {$numbers3}

How can I resolve it?

Answer 1

assigning the value to variable, not concatenate

$hashtag = $prefix . implode( '</div>' . $prefix, $tag ) . '</div>';

look at php string operators
