多维数组-如何从子数组中获取特定值 [英] Multidimensional array - how to get specific values from sub-array

问题描述

我具有以下数组结构:

Array
(
    [0] => Array
        (
            [product_option_id] => 236
            [option_id] => 14
            [name] => Masura S
            [type] => select
            [option_value] => Array
                (
                    [0] => Array
                        (
                            [product_option_value_id] => 33
                            [option_value_id] => 53
                            [name] => Alb
                            [price] => 
                            [price_prefix] => +
                        )

                    [1] => Array
                        (
                            [product_option_value_id] => 35
                            [option_value_id] => 55
                            [name] => Rosu
                            [price] => 
                            [price_prefix] => +
                        )

                )

            [required] => 0
        )

    [1] => Array
        (
            [product_option_id] => 237
            [option_id] => 15
            [name] => Masura M
            [type] => select
            [option_value] => Array
                (
                    [0] => Array
                        (
                            [product_option_value_id] => 34
                            [option_value_id] => 58
                            [name] => Rosu
                            [price] => 
                            [price_prefix] => +
                        )

                )

            [required] => 0
        )
)

我发现自己迷失了试图显示此数组中所有[name]值的机会.

I find myself lost in trying to display all the [name] values from this array.

我想做的是根据第一级[name](如[name] => Masura S)填充带有下拉选择的表单，然后根据第二级[name](如[name] => Alb)填充第二个下拉选择

What I am trying to do is to populate a form with dropdown selects based on the first level [name] (like [name] => Masura S) and then a second dropdown select with the second level [name] (like [name] => Alb).

如果您有任何指点，我将不胜感激...

I would appreciate it if you have any pointers...

推荐答案

您可以通过以下方式填充第一个选择:

You can populate the first select this way:

<select>

    <?php $c=count($array);
    for ( $i=0; $i < $c; $i++)
    { ?>
        <option><?php echo $array[$i]['name'];?></option>
    <?php } ?>   

</select>

第二次选择:

<select>

    <?php 
    for ( $i=0; $i < $c; $i++)
    { 
        $c2=count($array[$i]); 
        for ($j=0;$j<$c2;$j++){ 
    ?>
        <option><?php echo $array[$i][$j]['name'];?></option>
    <?php }} ?>

</select>
