PHP数组合并

问题描述

问 题

数组A

array(3) {
  [0] => array(1) {
    ["account"] => string(1) "6"
  }
  [1] => array(1) {
    ["account"] => string(1) "3"
  }
}

数组B

array(2) {
  [0] => array(1) {
    ["netfile"] => string(1) "7"

  }
  [1] => array(1) {
    ["netfile"] => string(1) "2"
  }
}

数组C

array(2) {
  [0] => array(1) {
    ["cf"] => string(1) "9"

  }
  [1] => array(1) {
    ["cf"] => string(1) "2"
  }
}

如何把这三个数组合并成

 array(4) {
  [0] => array(3) {
    ["netfile"] => string(1) "9"
    ["account"] => string(1) "6"
    ["cf"] => string(1) "9"

  }
  [1] => array(3) {
    ["netfile"] => string(1) "2"
    ["account"] => string(1) "3"
    ["cf"] => string(1) "2"
  }

求大神指导 感谢^^

解决方案

function mergeArr($a,$b,$c) {
        return array_merge($a,$b,$c);
}

$a = ['0'=>['account' => '6'],'1'=>['account' => '3']];
$b = ['0'=>['netfile' => '7'],'1'=>['netfile' => '2']];
$c = ['0'=>['cf' => '9'],'1'=>['cf' => '2']];
var_dump(array_map('mergeArr', $a,$b,$c));

输出：

array:2 [▼
  0 => array:3 [▼
    "account" => "6"
    "netfile" => "7"
    "cf" => "9"
  ]
  1 => array:3 [▼
    "account" => "3"
    "netfile" => "2"
    "cf" => "2"
  ]
]
