Question

以下是我的输入：

$firstname=array
("Raj","Swati","Kunal","Hema","Kareena","Deepika","Shilpa","Amitabh","Shahrukh","Kangana");

$lastname=array
("Kumar","Sharma","Kapoor","Malini","Kapoor","Padukone","Shetty","Amitabh","Shahrukh","Kangana");

我需要创建一个数组，它将$ firstname [i]与$ lastname [$ i}连接起来，从而创建一个结合了名字和姓氏的数组。

我的输出如下，但不正确：

<?php
foreach($firstname as $first){
   foreach($lastname as $last){
  $fullname[]=$first." ".$last;
  }
}
print_r($fullname);
?>

我可能不应该使用foreach循环但是我被卡住了。

Answer 1

假设大小相同的数组：

$firstname=array("Raj","Swati","Kunal","Hema","Kareena","Deepika","Shilpa","Amitabh","Shahrukh","Kangana");    
$lastname=array("Kumar","Sharma","Kapoor","Malini","Kapoor","Padukone","Shetty","Amitabh","Shahrukh","Kangana");
$size = count($firstname);
for ($i=0; $i < $size; $i++) {
    $fullname[]=$firstname[$i]." ".$lastname[$i];
}

Answer 2

这应该适合你：

（这里我只使用array_map()遍历两个数组，并将它们连接到$result数组中）

<?php

    $firstname = ["Raj", "Swati", "Kunal", "Hema", "Kareena", "Deepika", "Shilpa", "Amitabh", "Shahrukh", "Kangana"];
    $lastname = ["Kumar", "Sharma", "Kapoor", "Malini", "Kapoor", "Padukone", "Shetty", "Amitabh", "Shahrukh", "Kangana"];

    $result = array_map(function($v1, $v2){
        return "$v1 $v2";
    }, $firstname, $lastname);

    print_r($result);

?>

输出：

Array ( [0] => Raj Kumar [1] => Swati Sharma [2] => Kunal Kapoor [3] => Hema Malini [4] => Kareena Kapoor [5] => Deepika Padukone [6] => Shilpa Shetty [7] => Amitabh Amitabh [8] => Shahrukh Shahrukh [9] => Kangana Kangana )

Answer 3

如果您知道两个数组中的数据顺序正确：

$out=[];
foreach($firstname as $key=>$val)
    $out[$key] = $val . ' ' . $lastname[$key];

var_dump($out);

Answer 4

一种方法是使用array_combine;

$newArr = array_combine($firstname, $lastname);

foreach($newArr as $key => $value){
  echo $key." ".$value;
}

创建String数组在php中连接2个数组的元素
