Question

我有1个单个变量$input_args，其中似乎包含多个数组（多维？）：

Array（[required] => 1 [html_label_text] =>您的性别是什么？[required_validation_error_message] =>请输入您的性别[html_name] => ee_reg_qstn [356] [17] [html_id] => ee-reg-qstn [默认] => 男性）

Array（[required] => 1 [html_label_text] =>最喜欢的颜色？[required_validation_error_message] =>糟糕！好像缺少了一些东西[html_name] => ee_reg_qstn [356] [12] [html_id] => ee-reg-qstn [默认] => 蓝色）

Array（[required] => 1 [html_label_text] =>您的体重是多少？[required_validation_error_message] =>输入体重[html_name] => ee_reg_qstn [356] [18] [html_id] => ee -reg-qstn [默认] => 144 ）

我想隔离与[default]中的$input_args键相对应的不同值，但似乎无法做到这一点。回波$input_args['default']会产生所有值，即MaleBlue144，但是尝试单独选择这些值似乎是在设置值长度$input_args['default'][0]会产生MB1。

我是php新手。预先感谢您的帮助！

编辑：这是进行var_export

后的确切数组

array ( 'required' => true, 'html_label_text' => 'What is your gender?', 'required_validation_error_message' => 'Please enter your gender', 'html_name' => 'ee_reg_qstn[376][17]', 'html_id' => 'ee_reg_qstn-376-17', 'html_class' => 'ee-reg-qstn ee-reg-qstn-17', 'html_label_id' => 'ee_reg_qstn-376-17-lbl', 'html_label_class' => 'ee-reg-qstn', 'default' => 'Male', )array ( 'required' => true, 'html_label_text' => 'What is your color?', 'required_validation_error_message' => 'Oops!

Answer 1

如果要使用默认键的所有值，则可以使用array_column并将默认值指定为列键。

print_r(array_column($input_args, "default"));

结果

Array
(
    [0] => ** **Male**
    [1] => ** **Blue**
    [2] => ** **144**
)

如果您可能具有可以构成数组键的唯一数据，则可以指定第三个参数。例如：

array_column($input_args, "default", "html_name")

Demo

PHP-在看似复杂的数组中用相同的键隔离元素
