Php 将一个数组合并到另一个数组中

我有两个数组

阵列1：

array:3 [▼
  0 => 1
  1 => 2.3
  2 => 4.5
]

阵列2：

array:3 [▼
  0 => array:2 [▼
    "name" => "john"
    "age" => 34
  ]
  1 => array:2 [▼
    "name" => "doe"
    "age" => 12
  ]
  2 => array:2 [▼
    "name" => "kelvin"
    "age" => 14
  ]
]

如何将数组1合并到数组2中，从而得到如下内容-

array:3 [▼
      0 => array:3 [▼
        "name" => "john"
        "age" => 34,
        "score" => 1
      ]
      1 => array:3 [▼
        "name" => "doe"
        "age" => 12,
        "score" => 2.3
      ]
      2 => array:3 [▼
        "name" => "kelvin"
        "age" => 14,
        "score" => 4.5
      ]
    ]

---

请注意，数组1的值现在具有名为“score”的键

您可以将foreach循环与&:

输出：

Array
(
    [0] => Array
        (
            [name] => Joe
            [age] => 33
            [score] => 1
        )

    [1] => Array
        (
            [name] => Joe2
            [age] => 33
            [score] => 2
        )

    [2] => Array
        (
            [name] => Joe3
            [age] => 33
            [score] => 3.4
        )

)

您还可以使用来遍历阵列

<?php

$a = [1,2.3,4.5];

$b = [
    ["name" => "john", "age" => 34],
    ["name" => "doe","age" => 12],
    ["name" => "kelvin", "age" => 14]
];

array_walk($a,function($val,$key) use (&$b){
    $b[$key]['score'] = $val;  
});

print_r($b);

欢迎来到SO！请注意，堆栈溢出不是代码编写服务。我们总是很乐意帮助和支持新的程序员，但你需要先帮助自己。您应该尝试自己编写代码。请阅读和阅读。

<?php

$a = [1,2.3,4.5];

$b = [
    ["name" => "john", "age" => 34],
    ["name" => "doe","age" => 12],
    ["name" => "kelvin", "age" => 14]
];

array_walk($a,function($val,$key) use (&$b){
    $b[$key]['score'] = $val;  
});

print_r($b);
