$old_guanjianzi=我,的,php;
标签:<a href="tag.php?so=" foreach as urlencode>><?php echo $v;?></a>

这样分割关键字后只能显示一个关键字。怎么三个关键字用空格分割，每个关键字一个链接。

------解决方案--------------------

PHP code

$old_guanjianzi= "我,的,php";
$ar = explode(',', $old_guanjianzi);
foreach($ar as $v) echo "<a href="tag.php?so=%7B%24v%7D">{$v}</a> ";
<br><font color="#e78608">------解决方案--------------------</font><br>
