Foreach只返回一组数组

Question

我正在尝试使用此代码为http请求创建方法，但它只会获取1组键和值对（＆＃34; key_1＆＃34; =＆gt;＆＃34; value_1＆ ＃34）。我如何获得所有数组键及其值？

<?php
    $userPostData = [
        'key_1' => "value_1",
        'key_2' => "value_2"
    ];

  foreach($userPostData as $key => $value) {
    $response = $client->post($apiUrl, [
        'json' => [
             $key => urlencode($value),
        ],
        'verify' => false
        ]);
  }

您可以使用array_map对数组值进行urlencode。另外，我想你忘了把数组编码为json，所以我为你做了：

$userPostData = [
    'key_1' => "value_1",
    'key_2' => "value_2"
];

$userPostData = array_map('urlencode', $userPostData);

$response = $client->post($apiUrl, [
    'json'   => json_encode($userPostData), 
    'verify' => false
]);
