PHP中从两个并行索引数组创建关联数组的最简单方法是什么？

Question

Given the following two indexed arrays:

$a = array('a', 'b', 'c');
$b = array('red', 'blue', 'green');

What is the most straighforward/efficient way to produce the following associative array?:

$result_i_want = array('a' => 'red', 'b' => 'blue', 'c' => 'green');

Thanks.

Answer 1

array_combine

在你的情况下：

$result_i_want = array_combine($a, $b);

Answer 2

This should do it:

$a = array('a', 'b', 'c');
$b = array('red', 'blue', 'green');
$c = array_combine($a, $b);
print_r($c);

Result:

Array
(
    [a] => red
    [b] => blue
    [c] => green
)
