for循环遍历二维数组

for($i=0; $i <count($rows) ; $i++){
    echo '<tr>';
    echo '<td>'.$rows[$i]["uid"].'</td>';
    echo '<td>'.$rows[$i]["username"].'</td>';
    echo '<td>'.$rows[$i]["sex"].'</td>';
    echo '<td>'.$rows[$i]["email"].'</td>';
    echo '<td>'.$rows[$i]["phonenum"].'</td>';
    echo '<td>'.$rows[$i]["createtime"].'</td>';
    echo '</tr>';
}
