php连接数组的两个元素

Question

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);

我只想将 name 和 family 合并到 fullName 吗？

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");

我可以用这段代码来做

$count=0;
foreach($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？

只需在您当前的数组结构中分配一个新的 key 对值。一个简单的 foreach 就足够了:

$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");

foreach($MyArray as &$arr) {
                  // ^ reference
    $arr['fullName'] = "{$arr['name']} {$arr['family']}";
    //   ^ new key       ^ new value assignment
}
