多个数组合并问题

Question

我有两个数组

第一个数组

array(
    [0] => +970
    [1] => +971
    [2] => +972
)

和第二个数组

array(
    [0] => 465465454
    [1] => 321321355
    [2] => 987946546
)

我想这样合并它们

array(
    [+970] => 465465454
    [+971] => 321321355
    [+972] => 987946546
)

我尝试使用 array_merge 但这给了我不想要的结果，例如

$busi_code  = $page1_data->business_code; //array
$busi_num  = $page1_data->business_number; //array

$business_phone_numbers = array_merge($busi_code, $busi_num);

echo '<pre>';
print_r($business_phone_numbers);
echo '</pre>';

其结果是

[0] => +970
[1] => +971
[2] => +972
[3] => 465465454
[4] => 321321355
[5] => 987946546

所以请指导我怎样才能达到我想要的结果。

Answer 1

这是 array_combine 函数的作业：

$business_phone_numbers = array_combine($busi_code, $busi_num);

文档： http://php.net/manual/en/function.array-combine.php

Answer 2

您正在寻找 array_combine，而不是 array_merge:

Creates an array by using the values from the keys array as keys and the values from the values array as the corresponding values.

$business_phone_numbers = array_combine($busi_code, $busi_num);

Answer 3

您必须使用 array_combine。

试试这个：

$a = array(
0 => +970,
1 => +971,
2 => +972);

$b = array(
0 => 465465454,
1 => 321321355,
2 => 987946546);

$r = array_combine($a,$b);
print_r($r);
