你尝试了什么？
您的问题到底是什么？你想用 PHP 还是 jQuery 创建这个结构？您如何存储原始数据？
是的，我想要可以产生上述输出的 php 和 jquery 代码。

我假设您指的是它们的语法有何不同。我首先提供了一种在 PHP 中定义它的方法，然后我向您展示了一种在 JavaScript 中定义它的方法：

<?php

$json = Array( 
   "messages" => Array(   
      Array( 
         "from" => "InfoSMS",
         "to" => Array(   
            "41793026727",
            "41793026731"
         ),
         "text" => "May the Force be with you!"
      ),
      Array(   
         "from" => "41793026700",
         "to" => "41793026785",
         "text" => "A long time ago, in a galaxy far, far away... It is a period of civil war. Rebel spaceships, striking from a hidden base, have won their first victory against the evil Galactic Empire."
      )
   )
);

print_r($json);

?>

<script>

json = {  
   "messages":[  
      {  
         "from":"InfoSMS",
         "to":[  
            "41793026727",
            "41793026731"
         ],
         "text":"May the Force be with you!"
      },
      {  
         "from":"41793026700",
         "to":"41793026785",
         "text":"A long time ago, in a galaxy far, far away... It is a period of civil war. Rebel spaceships, striking from a hidden base, have won their first victory against the evil Galactic Empire."
      }
   ]
};

console.log(json);

</script>

【解决方案2】：

您可以在 PHP 数组上使用 json_encode() 将其转换为 JSON。您需要从数据集中生成类似的内容。

$data = [
    'messages'=> [
        [
            'from' => 'InfoSMS',
            'to' => [
                '41793026727',
                '41793026731',
            ],
            'text' => 'May the Force be with you!',
        ],
        [
            'from' => '41793026700',
            'to' => [
                '41793026785',
            ],
            'text' => 'A long time ago, in a galaxy far, far away... It is a period of civil war. Rebel spaceships, striking from a hidden base, have won their first victory against the evil Galactic Empire.',
        ],
    ],
];

echo json_encode($data);
