php语法如何将两个数组合并？

php语法如何将两个数组合并？下面web建站小编给大家详细介绍一下几种合并方法！

1、利用“+”运算符合并数组

header("content-type:text/html;charset=utf-8");
$x = array("A", "B", "C"); 
$y = array("1", "2", "3", "4"); 

//用+合并
$z = $x + $y;
//输出
var_dump($z);

2、利用array_combine()函数合并数组

$arr1 = array("A","B","C","D"); 
$arr2 = array("1","2","3","4"); 
$result = array_combine($arr1,$arr2); 
echo '<pre>';
var_dump($result);
