怎么把这个数组按照这这样的样式式排列?


value为cate_id
[code=HTML] <select>
<option value= "63 " > 奥迪A6L新型C6原厂资料 </option>
<option value= "64 " >   奥迪A6L新型C6原厂资料电路图 </option>

<option value= "65 " >     奥迪A6L新型C6原厂资料收音机电路图 </option>
<option value= "66 " > 奥迪A7原厂资料 </option>
<option value= "67 " >   奥迪a7a7原厂资料 </option>
<option value= "68 " >     奥迪a7a7a7a7原厂资料 </option>
<option value= "69 " >       奥迪a7a7a7a7a7a7a7a7原厂资料 </option>
</select> [/code]


这只是一个例子,这个数组可能是三维,四维的...

[解决办法]

PHP code

function func($ar, $deep=0) {  froeach($ar as $item) {    if(isset($item['cate_id'])) {      echo "<option value='$item[cate_id]'>".str_repeat(' ', $deep*2)."$item[cate_name]</option>";    else if(is_array($item)) func($item, $deep+1);  } . }echo '<select>';func($ar);echo '</select>';
