我在亚马逊 ec2 实例上使用 PHP 5.3.15 (cli)（构建时间：2012 年 7 月 20 日 23:10:20）。当我调用 json_encode() 时，生成的 JSON 会随机跳过字符，因此 JSON 不再有效。即使使用完全相同的参数/数据进行调用，这种情况也只会在某些时候发生。奇怪的是它发生在不同的地方，随机的地方，没有模式。在我的本地 MAMP 安装中，相同的数据和相同的代码以及相同版本的 PHP 不会发生这种情况

..."updateTime":"2012-12-21 03:24:14","createTime":"2012-12-21:"21","updateTime":"2012-12-25 19:33:25 “，……

你可以在 21:"21" 看到上面的效果。我什至不知道从哪里开始解决这个问题。

我已经重新启动，甚至创建了新的服务器虚拟实​​例。

我非常需要帮助。你能提出的任何建议都会很棒！！

您必须为 QUOT 或其他设置 json 编码参数 

 $json=json_encode($array,JSON_HEX_TAG | JSON_HEX_APOS | JSON_HEX_QUOT | JSON_HEX_AMP | JSON_UNESCAPED_UNICODE);

这是 php.net 上的 json 编码示例

 <?php
   $a = array('<foo>',"'bar'",'"baz"','&blong&', "\xc3\xa9");

   echo "Normal: ",  json_encode($a), "\n";
   echo "Tags: ",    json_encode($a, JSON_HEX_TAG), "\n";
   echo "Apos: ",    json_encode($a, JSON_HEX_APOS), "\n";
   echo "Quot: ",    json_encode($a, JSON_HEX_QUOT), "\n";
   echo "Amp: ",     json_encode($a, JSON_HEX_AMP), "\n";
   echo "Unicode: ", json_encode($a, JSON_UNESCAPED_UNICODE), "\n";
   echo "All: ",     json_encode($a, JSON_HEX_TAG | JSON_HEX_APOS | JSON_HEX_QUOT |JSON_HEX_AMP | JSON_UNESCAPED_UNICODE), "\n\n";

   $b = array();

   echo "Empty array output as array: ", json_encode($b), "\n";
   echo "Empty array output as object: ", json_encode($b, JSON_FORCE_OBJECT), "\n\n";

   $c = array(array(1,2,3));

   echo "Non-associative array output as array: ", json_encode($c), "\n";
   echo "Non-associative array output as object: ", json_encode($c, JSON_FORCE_OBJECT), "\n\n";

    $d = array('foo' => 'bar', 'baz' => 'long');

   echo "Associative array always output as object: ", json_encode($d), "\n";
   echo "Associative array always output as object: ", json_encode($d, JSON_FORCE_OBJECT), "\n\n";
 ?>

输出：

 Normal: ["<foo>","'bar'","\"baz\"","&blong&","\u00e9"]
 Tags: ["\u003Cfoo\u003E","'bar'","\"baz\"","&blong&","\u00e9"]
 Apos: ["<foo>","\u0027bar\u0027","\"baz\"","&blong&","\u00e9"]
 Quot: ["<foo>","'bar'","\u0022baz\u0022","&blong&","\u00e9"]
 Amp: ["<foo>","'bar'","\"baz\"","\u0026blong\u0026","\u00e9"]
 Unicode: ["<foo>","'bar'","\"baz\"","&blong&","é"]
 All: ["\u003Cfoo\u003E","\u0027bar\u0027","\u0022baz\u0022","\u0026blong\u0026","é"]

 Empty array output as array: []
 Empty array output as object: {}

 Non-associative array output as array: [[1,2,3]]
 Non-associative array output as object: {"0":{"0":1,"1":2,"2":3}}

 Associative array always output as object: {"foo":"bar","baz":"long"}
 Associative array always output as object: {"foo":"bar","baz":"long"}

我使用代理来分析发生了什么。我紧接着提出了两个相同的请求。重要的是要注意请求是在objective-c中，并且可能不是php破坏了，而只是第二个请求取消了第一个请求。
