在php中如何将特定的数组键分配给主数组[重复]

Question

我得到了下面的 o/p

$test1=["12","54","87","98"];
$test2=["1","5","8","9"];

那我如何将上面的两个变量连接到一个变量，如下所示

1 是 12 的键， 5 是 54 的键， 8 是 87 的键， 9 是 98 的键，

Answer 1

试试这个：

$test1=["12","54","87","98"];

$test2=["1","5","8","9"];

$a = array_combine($test2, $test1);

echo "<pre>";

print_r($a);

exit;

希望这会有所帮助。

和平！ xD

Answer 2

你可以试试这个

$test1=["12","54","87","98"];
$test2=["1","5","8","9"];


$new_array = array();

$i = 0;
foreach( $test2 as $key=> $value )
{
    $new_array[$value] = $test1[$i];
    $i++;
}

echo '<pre>';
print_r($new_array);
