用多个索引php加入一个数组

Question

如何将具有多个索引的2个数组连接到1个数组中？我有这样的数组

Array
(
    [0] => Array
        (
            [wd[wd5][amount]] => 1.00
            [wd[wd5][address]] => 1BitcoinAddress
            [wd[wd5][currency]] => BTC

        )

    [1] => Array
        (
            [wd[wd7][amount]] => 1.00
            [wd[wd7][address]] => 1BitcoinAddress
            [wd[wd7][currency]] => BTC

        )

)

我想将该数组转换/更改/合并为完全相同的东西

array(
        'wd[wd5][amount]' => 1.00,
        'wd[wd5][address]' => '1BitcoinAddress',
        'wd[wd5][currency]' => 'BTC',
        'wd[wd7][amount]' => 0.0001,
        'wd[wd7][address]' => '1BitcoinAddress',
        'wd[wd7][currency]' => 'BTC'

);

我怎么做 ？

Answer 1

使用call_user_func_array和array_merge

<?php

$array = [

    [
        "[wd[wd5][amount]]" => 1.00,
        "[wd[wd5][address]]" => "1BitcoinAddress",
        "[wd[wd5][currency]]" => "BTC"
    ],
    [
        "[wd[wd7][amount]]" => 1.00,
        "[wd[wd7][address]]" => "1BitcoinAddress",
        "[wd[wd7][currency]]" => "BTC"
    ]
];


$result = call_user_func_array('array_merge', $array);

echo "<pre>";
print_r($result);
