Question

有一些想法认为,从Xml或json的数据中产生一种下降的菜单。但是,我怎么能够完全与营地打交道? 一种可能的方法是建立一个多层次阵列。但是,从我的ql数据(使父母亲为补贴,以及如何有效地阅读阵列(通过 lo子吗?)中产生这种说法的最佳途径是什么?

<>strong>php>side,请请在座标上以各种形式检索:

$menu = array(
    page/1  =>  about ,
    page/2  =>  photos ,
    menu-title  =>  array( page/4  =>  sub-menu-1 , page/5  =>  sub-menu-2 )
);

echo  <ul> ;
foreach($menu as $key => $value){
  if(is_string($value)){
     echo  <li><a href=" .$key. "> .$value. </a></li> ;
  }
  if(is_array($value)){
    echo  <ul> ;
    echo  <li><a href="#"> .key($value). </a></li> ;
    foreach($value as $sub_key => $sub_value){
      echo  <li><a href=" .$sub_key . "> .$sub_value. </a></li> ;
    }
    echo  </ul> ;
  }
}
echo  </ul> ;

for mysql database, have a column of "parent_id" if it is null then it would be a root level, other than that, it would be a sub there, another column of "path" and "title,you can add a "weight" column as well to order them.

Answer 2

我愿通过从我sql中抽出的几行,并建立一个阵列,关键是投入的价值,其价值是案文。因此,如果你想像:

<input value="UT">Utah</input>
<input value="VT">Vermont</input>
<input value="NV">Nevada</input>
<input value="CA">California</input>

我将建立这样的阵列:

array(

       "UT" => "Utah",
       "VT" => "Vermont",
       "NV" => "Nevada",
       "CA" => "California",
)

It s very easy to translate the array into the html using a foreach.
