PHP - 解析新线日志

Question

我有以下的日志：

#VERSION: 2.9 2017-02-24 10:03:39 channel_ping 1afcd2e2857045fe973e7ed036ea450c dfe17897d80b44f6901593364fc72b55 2479884 127.0.0.1 Mozilla/5.0%20(Macintosh;%20Intel%20Mac%20OS%20X%2010_11_6)%20AppleWebKit/537.36%20(KHTML,%20like%20Gecko)%20Chrome/56.0.2924.87%20Safari/537.36 https://test.com/ TEST-User-50187 42134f99b57240d19e05f760800a9dc6

我可以读的这个内容在PHP没有问题，输出：

#VERSION: 2.9\n 2017-02-24\t10:03:39\tchannel_ping\t1afcd2e2857045fe973e7ed036ea450c\tdfe17897d80b44f6901593364fc72b55\t2479884\t127.0.0.1\tMozilla/5.0%20(Macintosh;%20Intel%20Mac%20OS%20X%2010_11_6)%20AppleWebKit/537.36%20(KHTML,%20like%20Gecko)%20Chrome/56.0.2924.87%20Safari/537.36\thttps://test.com/\tTEST-User-50187\t42134f99b57240d19e05f760800a9dc6\n """

我需要能够将其结构化为如下所示：

array[0] = '2017-02-24'; array[1] = '10:03:39'; array[2] = 'channel_ping';

Answer 1

您可以炸掉你的输出：

$arr = explode("\\t",$linesOf); 

或者，如果$ linesOf已经包含了\ T作为一个普通的字符串：

$arr = explode("\t",$linesOf); 

之前，我会做一个子摆脱了“＃的版本：2.9 \ n”个部分...

Answer 2

您可以使用正则表达式与preg_match_all：

preg_match_all("/\n(\w+?-\w+?-\w+)\t(\w+?:\w+?:\w+)\t([\w_]+)/", $strLog, $matches, PREG_PATTERN_ORDER); 

返回数组：

Array 
(
    [0] => Array 
     (
      [0] => 
2017-02-24 10:03:39 channel_ping 
     ) 

    [1] => Array 
     (
      [0] => 2017-02-24 
     ) 

    [2] => Array 
     (
      [0] => 10:03:39 
     ) 

    [3] => Array 
     (
      [0] => channel_ping 
     ) 
) 

最后，得到的值：

$date = $matches[1][0]; 
$time = $matches[2][0]; 
$command = $matches[3][0]; 

Answer 3

您可以使用以下。

使用preg_split，对所有的“空间”拆分字符\s

$res = preg_split('/\s/i',$str); 

然后，因为会有“空字符串”这是没用的是，我们与array_filter对结果进行筛选，以消除那些：

$res = array_filter($res, function($elem) { 
          // if it's not empty after trimming we can use it. 
          if (!empty(trim($elem))){ 
           return true; 
          } 
          return false; 
          }); 

看到它在acion：
