json_encode中多个阵列的日志管理

Question

我已经找了几天，阅读了多个线程，但没有找到任何答案。

这是我的问题：我正在重新制作CodeIgniter 3.XX上的日志管理。

我在这样的数组中收集每个日志消息的数据：

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

等等等等。 从每条日志消息中收集数据并将它们放在数组中没有问题。

问题是我想对数据进行 json 编码并在另一个控制器中解码它们以在仪表板上显示它们。

所以我用$log_message = json_encode($log_message, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES);

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"
}

经过几条消息，我得到了这个：

{
"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json_decode我的文件时，它不被视为 json 数组，所以我在每条消息之间添加了一个"，"来分隔它们，但我需要找到一种方法在开头写一个"["，在结尾写一个"]"，知道文件是由新的日志消息递增的。 你知道一种方法吗？

感谢您的建议，如果我的问题不清楚或可读性不强，请告诉我

试试这个，这样你就可以创建一个数组数组

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

加载完数据后，一个简单的

$messages = json_encode($log_message);

应该足够了，然后当你解码时，它应该很好地解码为一个对象数组。

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 - 漂亮打印

[
{
"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"
}

从Print_r($arr)

Array
(
[0] => stdClass Object
(
[message] => Severity: Compile Error --> Cannot redeclare Users::update_password_post() /application/controllers/api/Users.php 2055
[level] => ERROR

[short_message] => Users.php 2055
