我通過(guò) url 查詢字符串變量獲取，例如：myserver_state=1&myserver_running=2&myserver_mem=3目前我正在添加到現(xiàn)有的 json，例如：{ "key1": "1", "key2": "2", "key3": "3", "myserver_state": "1", "myserver_running": "2", "myserver_mem": "3"}我真的想要這樣：{ "key1": "1", "key2": "2", "key3": "3", "myserver": { "state": "1", "running": "2", "mem": "3" }}我用它來(lái)加載它們： $formdata = array( 'state'=> $_POST['state'], 'uassip'=> $_POST['uassip'], 'uassipport'=> $_POST['uassipport'], 'c_uacminrtpport'=> $_POST['c_uacminrtpport'], 'c_uacmaxrtpport'=> $_POST['c_uacmaxrtpport'], 'c_cps'=> $_POST['c_cps'], 'c_totalcalls'=> $_POST['c_totalcalls'], 'c_maxchannels'=> $_POST['c_maxchannels'], 'c_duration'=> $_POST['c_duration'], 'c_to'=> $_POST['c_to'], 'c_uacxml'=> $_POST['c_uacxml'] ); echo "fromdata: <br>"; echo var_dump($formdata) . "<br><hr>"; if(file_put_contents('testconfig.json', json_encode($formdata) )) echo 'OK'; else echo 'Unable to save data in "testconfig.json"';非常感謝！編輯：我嘗試過(guò)以下評(píng)論：status.php?server1[當(dāng)前狀態(tài)]=10這實(shí)際上可以： "c_uacxml": "telnyx-uac-invite-ok.xml", "server1": { "current_state": "10" }}這很棒，但是，如果我想添加這樣的元素：status.php?server1[current_mem]=1這實(shí)際上取代了整個(gè)server1 "c_uacxml": "telnyx-uac-invite-ok.xml", "server1": { "current_mem": "10" }}我失去了已經(jīng)存在的 current_state

只需在 URL 中使用多維數(shù)組，例如：
test.php?key1=1&key2=2&myserver[state]=1&myserver[running]=2&myserver[mem]=3
如此簡(jiǎn)單的腳本
<?php
echo '<pre>';
echo json_encode($_GET, JSON_PRETTY_PRINT);
會(huì)給你
{
"key1": "1",
"key2": "2",
"myserver": {
"state": "1",
"running": "2",
"mem": "3"
}
}
當(dāng)然，如果需要，您也可以使用具有相同命名規(guī)則的 POST 請(qǐng)求。

為了創(chuàng)建嵌套的 JSON 對(duì)象，您需要在數(shù)組中創(chuàng)建數(shù)組。
例如
$example = [
'key1' => 'foo',
'key2' => 'bar',
'key3' => [
'subkey1' => 'foo',
'subkey2' => 'bar',
],
];
當(dāng)運(yùn)行它時(shí)json_encode()，它會(huì)導(dǎo)致
{
"key1": "foo",
"key2": "bar",
"key3": {
"subkey1": "foo",
"subkey2": "bar"
}
}
也沒(méi)有必要像這樣加載表單數(shù)據(jù) –
$formdata = [
'state' => $_POST['state'],
'uassip' => $_POST['uassip'],
'uassipport' => $_POST['uassipport'],
'c_uacminrtpport' => $_POST['c_uacminrtpport'],
'c_uacmaxrtpport' => $_POST['c_uacmaxrtpport'],
'c_cps' => $_POST['c_cps'],
'c_totalcalls' => $_POST['c_totalcalls'],
'c_maxchannels' => $_POST['c_maxchannels'],
'c_duration' => $_POST['c_duration'],
'c_to' => $_POST['c_to'],
'c_uacxml' => $_POST['c_uacxml'],
];
因?yàn)?_POST已經(jīng)包含您正在嘗試重新創(chuàng)建的結(jié)構(gòu)。您只需將發(fā)布數(shù)據(jù)分配給新變量即可。
另一方面，我強(qiáng)烈建議您查看 PSR PHP 標(biāo)準(zhǔn)，它們將極大地幫助提高代碼可讀性和代碼結(jié)構(gòu):) https://www.php-fig.org/psr/
