以json内容格式返回文件

问题描述：

I have a txt file with this structure:

17/02/2016 9:50 [info] "hello"
17/02/2016 10:20 [debug] "world"

now I'm trying to read it with:

$fh = fopen($this->_logPath, "r");
$content = array(); 

while ($line = fgets($fh))
{
    array_push($content, $line);
}
fclose($fh);

return json_encode($content);

the file is readed correctly but, in my chrome extension for try Rest API I get in the json tab:

unexpected string

how I can return each line in json content? For example a result like this:

"trace": {
     info: {
         date: {
             "17/02/2016 9:50" {
                -"content": "hello"
            }     
         }
       } 
     debug: {
          date: { 
             "17/02/2016 10:20" {
               -"content": "world"
              }  
          }
       }
    }

or if someone have a better organization I'll glad to see.

我有一个具有这种结构的txt文件： p>

  17  / 02/2016 9:50 [info]“你好”
17 / 02/2016 10:20 [调试]“世界”
  code>  pre> 
 
 现在我正在尝试 阅读它： p> 
 
 
  $ fh = fopen（$ this-＆gt; _logPath，“r”）; 
 $ content = array（）;  
 
而（$ line = fgets（$ fh））
 {
 array_push（$ content，$ line）; 
} 
 nclclose（$ fh）; 
 
return json_encode（$ content）; 
   code>  pre> 
 
 文件被正确加入，但是在我的chrome扩展程序中尝试使用Rest API我进入json选项卡： p> 
 
 
 
  意外字符串 p> 
  blockquote> 
 
 
如何返回json内容中的每一行？ 例如，结果如下： p> 
 
 
 “trace”：{
 info：{
 date：{
“17/02/2016 9:50”{\  n  - “content”：“hello”
} 
} 
} 
 debug：{
 date：{
“17/02/2016 10:20”{
  - “content”：“world  “
} 
} 
} 
} 
  code>  pre> 
 
 或者如果有人有更好的组织，我很乐意看到。 p> 
   DIV>

答

I would choose a structure like this:

{  
   "trace":[  
      {  
         "date":"17/02/2016 9:50",
         "level":"debug",
         "message":"hello"
      },
      { 
         "date":"17/02/2016 9:50",
         "level":"debug",
         "message":"hello"
      }
   ]
}

Notice that trace contains an array of logitems. To parse your file, following should work:

$fh = fopen($this->_logPath, "r");
$content = array(); 
$content["trace"] = array();

while ($line = fgets($fh))
{
    $raw = preg_split("/[\[\]]/", $line); //splits string at [ and ], results in an array with three items
    $entry = array();
    $entry["date"] = trim($raw[0]);
    $entry["level"] = trim($raw[1]);
    $entry["message"] = trim($raw[2]);
    $content["trace"][] = $entry;
}
fclose($fh);
return json_encode($content);
