產生通過在數組中循環「選擇輸入」

Question

我有以下陣列：

$selects = array(
     'Select1' => array('select1_name' => array('select1_value1','select1_value1')), 
     'Select2' => array('select2_name' => array('select2_value1','select2_value2')) 
    ); 

我不知道如何可以生成這些通過一個循環他們的選擇「選擇輸入」？

Answer 1

你需要一個週期，這將遍歷數組選擇，這裏面循環，你需要一個又一個，這將遍歷選擇。而這一次裏面，你需要多一個，這將遍歷選項值：

$selects = array(
    'Select1' => array('select1_name' => array('select1_value1','select1_value1')), 
    'Select2' => array('select2_name' => array('select2_value1','select2_value2')) 
); 

foreach($selects as $select) { 
    foreach($select as $item) { 
     echo "<select>"; 
     foreach($item as $value) { 
      echo "<option value=".$value.">".$value."</option>"; 
     } 
     echo "</select>"; 
    } 
} 

這將產生：

<select> 
 
    <option value=select1_value1>select1_value1</option> 
 
    <option value=select1_value1>select1_value1</option> 
 
</select> 
 
<select> 
 
    <option value=select2_value1>select2_value1</option> 
 
    <option value=select2_value2>select2_value2</option> 
 
</select>

Answer 2

foreach($selects as $select) { 
    foreach($select as $selectName => $value) { 
      echo '<select> '; 
      echo '<option>'.$selectName.'</option>'; 
      foreach($value as $v) { 
       echo '<option>'.$v.'</option>'; 
      } 
      echo '</select>'; 
    } 
} 

Answer 3

echo '<select> '; 
    foreach($selects as $array) {  
    foreach($array as $value) {  
       foreach($value as $v) { 
       echo '<option value="'.$v.'">'.$v.'</option>'; 
      }}}  
    echo '</select>';
