PHP加入数组的两个元素

我有这个数组

$MyArray[0]=Array("id"=>1,"name"=>prophet,"family"=>muhammad);
$MyArray[1]=Array("id"=>1,"name"=>imam,"family"=>ali);
$MyArray[2]=Array("id"=>1,"name"=>imam,"family"=>hossein);

我想合并只是name和family以fullName？

我想要这样

$MyArray[0]=Array("id"=>1,"name"=>prophet,"family"=>muhammad,"fullName"=>"prophet muhammad");
$MyArray[1]=Array("id"=>1,"name"=>imam,"family"=>ali,"fullName"=>"imam ali");
$MyArray[2]=Array("id"=>1,"name"=>imam,"family"=>hossein,"fullName"=>"imam hossein");

我可以用这段代码

$count=0;
foreach($MyArray as $R)
{            
    $result[$count++]=array("name"=>$R["name"],"family"=>$R["family"],"fullName"=>$R["name"]." ".$R["family"]);
}
var_dump($result);

有更好的方法吗？

您可以array_map()像这样在代码中使用：

<?php

$MyArray[0]=Array("id"=>1,"name"=> "prophet", "family"=> "muhammad");
$MyArray[1]=Array("id"=>1,"name"=> "imam", "family"=> "ali");
$MyArray[2]=Array("id"=>1,"name"=> "imam", "family"=> "hossein");

$array = array_map(function($n) {$n['fullName'] = $n['name'] . ' ' . $n['family']; return $n;}, $MyArray);

print_r($array);

输出：

Array
(
    [0] => Array
        (
            [id] => 1
            [name] => prophet
            [family] => muhammad
            [fullName] => prophet muhammad
        )

    [1] => Array
        (
            [id] => 1
            [name] => imam
            [family] => ali
            [fullName] => imam ali
        )

    [2] => Array
        (
            [id] => 1
            [name] => imam
            [family] => hossein
            [fullName] => imam hossein
        )

)
