Php 在json_encode中使用多个数组进行日志管理

我已经找了好几天了，读了很多文章，但我没有找到任何答案

这是我的问题：我正在重新设计CodeIgniter 3.XX上的日志管理

我收集数组中每个日志消息的数据，如下所示：

$log_message['date'] = $date
$log_message['severity'] = $severity
$log_message['message'] = $message

等等。 从每个日志消息中收集数据并将其放入阵列中是没有问题的

问题是，我想对数据进行json编码，并在另一个控制器中对其进行解码，以便在仪表板上显示它们

所以我用

$log\u message=json\u encode（$log\u message、json\u PRETTY\u PRINT、json\u UNESCAPED\u斜线）

结果如下：

{
    "message": "Severity: Compile Error --> Cannot redeclare Users::update_password_post() /application/controllers/api/Users.php 2055",
    "level": "ERROR",
    "date": "2019-10-21 16:53:24",
    "short_message": "Users.php 2055",
    "severity": "Compile",
    "ip": "",
    "trace": [
        "core/Common.php MY_Exceptions->log_exception() (line:618)"
    ],
    "short_trace": "core/Common.php MY_Exceptions->log_exception() (line:618)",
    "uri": "[POST] /api/users/user"
}



几次留言后，我得到了以下信息：

{
    "message": "Severity: Compile Error --> Cannot redeclare Users::update_password_post() /application/controllers/api/Users.php 2055",
    "level": "ERROR",
    "date": "2019-10-21 16:53:24",
    "short_message": "Users.php 2055",
    "severity": "Compile",
    "ip": "",
    "trace": [
        "core/Common.php MY_Exceptions->log_exception() (line:618)"
    ],
    "short_trace": "core/Common.php MY_Exceptions->log_exception() (line:618)",
    "uri": "[POST] /api/users/user"
}{
    "message": "Severity: Compile Error --> Cannot redeclare Users::update_password_post() /application/controllers/api/Users.php 2055",
    "level": "ERROR",
    "date": "2019-10-21 16:53:24",
    "short_message": "Users.php 2055",
    "severity": "Compile",
    "ip": "",
    "trace": [
        "core/Common.php MY_Exceptions->log_exception() (line:618)"
    ],
    "short_trace": "core/Common.php MY_Exceptions->log_exception() (line:618)",
    "uri": "[POST] /api/users/user"
}

但是当我想要对我的文件进行json_解码时，它并不被视为json数组，所以我在每个表页之间添加了一个“，”来分隔它们，但我需要找到一种方法，在开始时写一个“[”，在结束时写一个“]”，因为我知道新的日志消息会增加文件。
你知道怎么做吗

感谢您的建议，如果我的问题不清楚或可读性不好，请告诉我
试试这个，这样您就可以创建一个数组了

$line['date'] = $date;
$line['severity'] = $severity;
$line['message'] = $message;

$log_message[] = $line;

当您完成加载数据时，一个简单的

$messages = json_encode($log_message);

应该足够了，然后当您解码时，它应该作为一个对象数组很好地解码

更好的示例代码

$line = [
        "message" => "Severity: Compile Error --> Cannot redeclare Users::update_password_post() /application/controllers/api/Users.php 2055",
        "level" => "ERROR",
        "date" => "2019-10-21 16:53:24",
        "short_message" => "Users.php 2055",
        "severity" => "Compile",
        "ip" => "",
        "trace" => ["core/Common.php MY_Exceptions->log_exception() (line:618)"],
        "short_trace" => "core/Common.php MY_Exceptions->log_exception() (line:618)",
        "uri" => "[POST] /api/users/user"
        ];

$log_message[] = $line;

$line = [
        "message" => "Severity: Compile Error --> Cannot redeclare Users::update_password_post() /application/controllers/api/Users.php 2055",
        "level" => "ERROR",
        "date" => "2019-10-21 16:53:24",
        "short_message" => "Users.php 2055",
        "severity" => "Compile",
        "ip" => "",
        "trace" => ["core/Common.php MY_Exceptions->log_exception() (line:618)"],
        "short_trace" => "core/Common.php MY_Exceptions->log_exception() (line:618)",
        "uri" => "[POST] /api/users/user"
        ];

$log_message[] = $line;

$messages = json_encode($log_message, JSON_PRETTY_PRINT );
print $messages;

$arr = json_decode($messages);
print_r($arr);

结果：
JSON字符串-预打印

[
    {
        "message": "Severity: Compile Error --> Cannot redeclare Users::update_password_post() \/application\/controllers\/api\/Users.php 2055",
        "level": "ERROR",
        "date": "2019-10-21 16:53:24",
        "short_message": "Users.php 2055",
        "severity": "Compile",
        "ip": "",
        "trace": [
            "core\/Common.php MY_Exceptions->log_exception() (line:618)"
        ],
        "short_trace": "core\/Common.php MY_Exceptions->log_exception() (line:618)",
        "uri": "[POST] \/api\/users\/user"
    },
    {
        "message": "Severity: Compile Error --> Cannot redeclare Users::update_password_post() \/application\/controllers\/api\/Users.php 2055",
        "level": "ERROR",
        "date": "2019-10-21 16:53:24",
        "short_message": "Users.php 2055",
        "severity": "Compile",
        "ip": "",
        "trace": [
            "core\/Common.php MY_Exceptions->log_exception() (line:618)"
        ],
        "short_trace": "core\/Common.php MY_Exceptions->log_exception() (line:618)",
        "uri": "[POST] \/api\/users\/user"
    }

谢谢你的建议，但是现在当我想验证我的json时，我得到了多个json根元素错误，因为我的数组的末尾和开头都有“][”。也许正则表达式可以完成这项工作？这段代码不会创建这些。那么你是如何真正创建json字符串的呢？我今天早上在工作中尝试过这种方式：$log[]=$log\u message；$logs=json\u encode（$log，json\u UNESCAPED\u SLASHES）；问题是一样的，我仍然在每条消息中得到一个数组，如下所示：[{array}][{array}]谢谢你的帮助，我使用并修改了你的代码，它工作正常！
