如何在PHP中遍历值的同时将多个值放入数组中

Question

好吧，所以我正在尝试调整一个数组并将其解码为json，目前它解码数组是这样的；

{"campaignId":"18210f12-502c-4d71-a098-4f595304a8d0","fields.CPLastName":"Voornaam 1","fields.CPFirstname":"Achternaam 1","fields.OROrganisation":"Bedrijf 1"}
{"campaignId":"18210f12-502c-4d71-a098-4f595304a8d0","fields.CPLastName":"Voornaam 2","fields.CPFirstname":"Achternaam 2","fields.OROrganisation":"Bedrijf 2"}

代码：

$request = array();
foreach($address_data as $address) {
foreach($address as $key => $value){
if($key == 'campaignId') {
$request[$key] = $value;
}
if (strpos($key, 'fields') !== false) {
$fields = explode('.', $key);
$request['fields'] = array(
array('fieldId' => $fields[1], 'value' => $value)
);
}
}
echo json_encode($request);
}

我想做的是，它说在哪里；字段。我想在此基础上展开并替换字段。fieldId在字段数组中。这样的事情；

$request['fields'] = array(array('fieldId' => $key, 'value' => $value));

现在由于某种原因，它只会执行最后一个键，我希望它在所有写着"字段"的键中循环

因此，最后的请求应该看起来像；

{   
"campaignId":"18210f12-502c-4d71-a098-4f595304a8d0",
"fields": [
{
"fieldId":"CPLastName",
"value":"Voornaam 1"
},
{
"fieldId": "CPFirstname",
"value": "Achternaam 1"
},
{
"fieldId":"OROrganisation",
"value":"Bedrijf 1"
}
]
}
{   
"campaignId":"18210f12-502c-4d71-a098-4f595304a8d0",
"fields": [
{
"fieldId":"CPLastName",
"value":"Voornaam 2"
},
{
"fieldId": "CPFirstname",
"value": "Achternaam 2"
},
{
"fieldId":"OROrganisation",
"value":"Bedrijf 2"
}
]
}

在这种情况下使用临时辅助变量，即为.中的单个项组装数组数据结构

将该临时数组添加到外部循环末尾的结果数组中。

$request = [];
foreach($address_data as $address) {
$temp = [];
foreach($address as $key => $value){
if($key == 'campaignId') {
$temp[$key] = $value;
}
if (strpos($key, 'fields') !== false) { // === 0 would perhaps make more sense here
$fields = explode('.', $key);
$temp['fields'][] = [
'fieldId' => $fields[1],
'value' => $value
];
}
}
$request[] = $temp;
}
echo json_encode($request);
