通过数组中的循环生成“选择输入”

Question

我有以下数组：

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

我想知道如何通过循环生成这些“选择输入”及其选项吗？

Answer 1

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 2

您需要一个循环，该循环将遍历selects数组，在此循环内，您需要另一个循环，将遍历selects数组。 在这一个里面，您还需要一个，它将遍历选项值：

$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>";
    }
}

这将产生：

 <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>

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