我有两个来自HTML表单的数据数组。
Array1（payment_descriptions）看起来像这样：

["1st Desc","2nd Desc","3rd Desc"]

字符串
Array2（payment_amounts）是这样的：

["100.10","10.50","39.99"]

型
有没有一种方法可以将这些数组（付款）合并组合起来，使最终结果看起来像这样？

[{
    "description": "1st Desc",
    "amount": "100.10"
}, {
    "description": "2nd Desc",
    "amount": "10.50"
}, {
    "description": "3rd Desc",
    "amount": "39.99"
}]

你可以用简单的array_combine()和foreach()循环来实现：

<?php
$arr1 = ["1st Desc","2nd Desc","3rd Desc"];
$arr2 =["100.10","10.50","39.99"];

$combined = array_combine($arr1,$arr2);
$expected = [];
foreach($combined as $k=>$v){
    $expected[] = ['description'=>$k,'amount'=>$v];
}
echo json_encode($expected,JSON_PRETTY_PRINT);
?>

字符串

无 * array_combine()：

foreach($arr1 as $k=>$v){
    $expected[$k] = ['description'=>$v,'amount'=>$arr2[$k]];
}
