Question

我想将这个格式化的字符串转换为多维数组，但我无法做到。

目标是提取标题标题（ Dreg Time，FN，SS_ID，MAC，Sector ID，Type，Reason，CMPNT，Basic，Cid ）并关联相应的值。

因为在最终结果中，我需要处理“原因”列中的数据。

字符串：

$log = ": mss get dereg_log 2 500



---------- MODEM 2 MAC ---------



Dreg Time                   FN       SS_ID     MAC           Sector ID Type Reason CMPNT Basic Cid

2017/08/29 08:20:39:627   0x4da9f0  8277 00:24:a0:xx:xx:xx         1    2     25     0        86

2017/08/29 07:17:33:478   0x421c02  8238 00:23:a2:xx:xx:xx         1    3     59     0        47

2017/08/29 06:00:43:232   0x340a41  8508 00:23:a2:xx:xx:xx         1    1      6    13       317



Total Deregistrations since sector active in sector 1: 9576

Derigistrations since dreg log last reset in sector 1: 9576



Deregistration Types:

    DEREG_MSS_IMMEDIATE = 0

    DEREG_MSS_DREG_REQ_FROM_AP = 1

    DEREG_MSS_DREG_REQ_FROM_MS = 2

    DEREG_MSS_RNG_RSP_ABORT_FROM_AP = 3

    DEREG_MSS_CONTACT_LOST = 4



---------------------------------

2017-Aug-29 08:31:53.860";

所需数组：

Array
(
    [0] => Array
        (
            [Dreg Time] => '2017/08/29 08:20:39:627'
            [FN] => '0x4da9f0'
            [SS_ID] => '8277'
            [MAC] => '00:24:a0:xx:xx:xx'
            [Sector ID] => '1'
            [Type] => '2'
            [Reason] => '25'
            [CMPNT] => '0'
            [Basic Cid] => '86'
        )

    [1] => Array
        (
            [Dreg Time] => '2017/08/29 07:17:33:478'
            [FN] => '0x421c02'
            [SS_ID] => '8238'
            [MAC] => '00:23:a2:xx:xx:xx'
            [Sector ID] => '1'
            [Type] => '3'
            [Reason] => '59'
            [CMPNT] => '0'
            [Basic Cid] => '47'
        )

    [2] => Array
        (
            [Dreg Time] => '2017/08/29 06:00:43:232'
            [FN] => '0x340a41'
            [SS_ID] => '8508'
            [MAC] => '00:23:a2:xx:xx:xx'
            [Sector ID] => '1'
            [Type] => '1'
            [Reason] => '6'
            [CMPNT] => '13'
            [Basic Cid] => '317'
        )
)

代码尝试：

echo '<pre>';
// remove blank lines
$log = preg_replace("/(^[\r\n]*|[\r\n]+)[\s\t]*[\r\n]+/", "\n", $log);
// remove new lines
$log = preg_replace('/^.+\n.+\n/', '', $log);

$lines = explode( "\n\n", $log );
$return = array();

foreach ($lines as $line) {
  $items = explode("\n", $line);
  $return[array_shift($items)] = $items;
}

print_r($return);

结果：

Array
(
    [Dreg Time                   FN       SS_ID     MAC           Sector ID Type Reason CMPNT Basic Cid] => Array

            [3] => Total Deregistrations since sector active in sector 1: 9576

您的代码是一次不完整的尝试，并包含一些错误 - 例如您从日志中删除了换行符，然后尝试根据换行符拆分字符串！然后你尝试用换行符拆分一行，显然单行不能包含换行符。此外，代码只是天真地遍历每一行并将其直接添加到数组中，而不是在每个索引中创建一个关联数组，如所需的输出所示。最后，它没有尝试确定哪些行实际包含所需的输出。

这样做：

$log = preg_replace("/(^[\r\n]*|[\r\n]+)[\s\t]*[\r\n]+/", "\n", $log);
$lines = explode( "\n", $log );
$return = array();

foreach ($lines as $line) {
  $line = preg_replace("/\s+/", " ", $line); //condense and standardise the whitespace between each item, so that explode can work.
  $items = explode(" ", $line);
  if (count($items) == 10 && preg_match("/^[0-9]{4}/", $items[0])) //restrict to lines starting with the year, and with the correct number of columns
      $return[] = array(
            "Dreg Time" => $items[0]." ".$items[1],
            "FN" => $items[2],
            "SS_ID" => $items[3],
            "MAC" => $items[4],
            "Sector_ID" => $items[5],
            "Type" => $items[6],
            "Reason" => $items[7],
            "CMPNT" => $items[8],
            "Basic_Cid" => $items[9]
      );
}

 echo "<pre>".var_export($return, true)."</pre>";
