这是我目前拥有的数组，请将其转换为下面的单维数组:-
Array
(
[0] => Array
(
[is_custom] => yes
)
[1] => Array
(
[custom_amount] => 45
)
[2] => Array
(
[custom_amount_text] => Enter Amount
)
[3] => Array
(
[amount_btn] => Dropdown
)
[4] => Array
(
[multiple_amounts] => W3sidGl0bGUiOiJMYWJlbCIsImFtb3VudCI6IjQ1In0seyJ0aXRsZSI6IkxhYmVsIiwiYW1vdW50IjoiNDU1In1d
)
[5] => Array
(
[recurring_plans] => W3sibmFtZSI6IkxhYmVsIiwicmVjdXJyaW5nX2Ftb3VudCI6Ijc4In0seyJuYW1lIjoidSIsInJlY3VycmluZ19hbW91bnQiOiI3ODgifV0=
)
[6] => Array
(
[recurring_interval] => WyJNb250aGx5IiwiUXVhcnRlcmx5IiwiSGFsZi1ZZWFybHkiXQ==
)
[7] => Array
(
[admin_mail_subject] =>
)
[8] => Array
(
[admin_mail_body] =>
)
[9] => Array
(
[user_mail_subject] =>
)
[10] => Array
(
[user_mail_body] =>
)
[11] => Array
(
[is_recurrance] => yes
)
[12] => Array
(
[is_onetime] => yes
)
)
现在我想把它转换成这样的格式
Array([0]=>
[is_custom] => yes
[custom_amount] => 45
[custom_amount_text] => Enter Amount
[amount_btn] => Dropdown
[multiple_amounts] => W3sidGl0bGUiOiJMYWJlbCIsImFtb3VudCI6IjQ1In0seyJ0aXRsZSI6IkxhYmVsIiwiYW1vdW50IjoiNDU1In1d
[recurring_plans] => W3sibmFtZSI6IkxhYmVsIiwicmVjdXJyaW5nX2Ftb3VudCI6Ijc4In0seyJuYW1lIjoidSIsInJlY3VycmluZ19hbW91bnQiOiI3ODgifV0=
)
数组0键将有所有的键可以，这是可能的。我试过了，但失败了。请给我一个可能的解决方案
使用RecursiveIteratorIterator快速和简单。
$output_array = iterator_to_array(new RecursiveIteratorIterator(new RecursiveArrayIterator($input_array)), 0); //$input_array-Replace your arrray
echo "<pre>";
print_r($output_array);
echo "</pre>";
Array
(
[0] => yes
[1] => 45
[2] => Enter Amount
[3] => Dropdown
[4] => W3sidGl0bGUiOiJMYWJlbCIsImFtb3VudCI6IjQ1In0seyJ0aXRsZSI6IkxhYmVsIiwiYW1vdW50IjoiNDU1In1d
[5] => W3sibmFtZSI6IkxhYmVsIiwicmVjdXJyaW5nX2Ftb3VudCI6Ijc4In0seyJuYW1lIjoidSIsInJlY3VycmluZ19hbW91bnQiOiI3ODgifV0=
[6] => WyJNb250aGx5IiwiUXVhcnRlcmx5IiwiSGFsZi1ZZWFybHkiXQ==
[7] =>
[8] =>
[9] =>
[10] =>
[11] => yes
[12] => yes
)

$newArray=array_map(function($v){
return current($v);
},$oldArray);
