Question

我正在显示mysql的列表。（http://www.jetcleandrives.co.uk/Areas_Covered.php）

这是代码，

if ($rows['area_shire'] != $area_shire && isset ($rows['area_shire'])){   
        $area_shire = $rows['area_shire'];
            $area_shire_url = str_replace(' ', '_', $area_shire);
        echo '<div class="area_name"><h2><a href=Driveway_Cleaning_'.$area_shire_url.'>'.$area_shire.'</a></h2></div><br>';

    }  

    echo '<div class "areas_column">';     
    if ($rows['area_district'] != $area_district && isset ($rows['area_district'])){
        $area_district = $rows['area_district'];
        $area_district_url = str_replace(' ', '_', $area_district);
        echo '<div class="area_name"><h3><a href=Driveway_Cleaning_'.$area_district_url.'>'.$area_district.'</a></h3></div><br>';

    }  



    if ($rows['area_name'] != $area_name &&  isset ($rows['area_name'])){
        $area_name = $rows['area_name'];
        $area_name_url = str_replace(' ', '_', $area_name);
        echo '<div class="area_name"><a href=Driveway_Cleaning_'.$area_name_url.'>'.$area_name.'</a></div><br>';

但是我不希望它成为一个长的Verticle列表。我希望每个区域，例如Birmingham，Sandwell等，使用divs和float开始一个新的“列”：left但是我无法找到从哪里开始并关闭div。有人可以帮忙吗？

尝试这样的事情：

$area_district = null; // set this to null initially, so you can identify the first iteration
if ($rows['area_shire'] != $area_shire && isset ($rows['area_shire'])){   
    $area_shire = $rows['area_shire'];
    $area_shire_url = str_replace(' ', '_', $area_shire);
    echo '<div class="area_name"><h2><a href=Driveway_Cleaning_'.$area_shire_url.'>'.$area_shire.'</a></h2></div><br>';

}  

if ($rows['area_district'] != $area_district && isset ($rows['area_district'])){
    if($area_district!==null) echo '</div>'; // only close the previous div if this isn't the first
    echo '<div class "areas_column">'; // open the div only when the district changes
    $area_district = $rows['area_district'];
    $area_district_url = str_replace(' ', '_', $area_district);
    echo '<div class="area_name"><h3><a href=Driveway_Cleaning_'.$area_district_url.'>'.$area_district.'</a></h3></div><br>';

}  

if ($rows['area_name'] != $area_name &&  isset ($rows['area_name'])){
    $area_name = $rows['area_name'];
    $area_name_url = str_replace(' ', '_', $area_name);
    echo '<div class="area_name"><a href=Driveway_Cleaning_'.$area_name_url.'>'.$area_name.'</a></div><br>';
}
echo '</div>'; // close the last div

打开和关闭数组中的div
