查询sql获得5条数据,我想把获得的这5条数据以以下方式表现,该什么弄呢?
想要达到的效果如下:
arr={你好,我好,大家好,很好,太好了};
foreach arr 后怎么达到下面的输出效果?

  • 我好

  • 大家好



  • 很好

  • 太好了

    $arr = array('你好', '我好', '大家好', '很好', '太好了');foreach($arr as $k=>$v) {  if($k == 0) echo "<dl>$v</dl>\n<div>";  if($k % 2 == 1) echo "<ul id=" . ceil($k / 2) . ">\n";  echo "<li>$v</li>\n";}echo "<div>";
    Copy after login
    <dl>你好</dl><div><li>你好</li><ul id=1><li>我好</li><li>大家好</li><ul id=2><li>很好</li><li>太好了</li><div>
    Copy after login

    $arr = array('你好', '我好', '大家好', '很好', '太好了');foreach($arr as $k=>$v) {  if($k == 0) echo "<dl>$v</dl>\n<div>";  if($k % 2 == 1) {    if(ceil($k / 2) > 1) echo "</ul>\n";    echo "<ul id=" . ceil($k / 2) . ">\n";  }  echo "<li>$v</li>\n";}echo "</ul>\n<div>";
    Copy after login
