PHP:过滤字符串中的特定模式

PHP:过滤字符串中的特定模式

问题描述:

My raw output of socket_recvfrom is:

ID IP PING IDENTIFIERNUMBER USERNAME


0 127.0.0.1:1234 0 ID123456789 Moritz

1 127.0.0.1:1234 46 ID123456789 August Jones

2 127.0.0.1:1234 46 ID123456789 Miller


It is a single string that contains all of this informations in once and just contains whitespaces between the informations. All keys can be longer or shorter.

My problem:

When I preg_split("/\s+/") it, then I get a good array with useable data, but when the username contains spaces it creates a second index for this. Not good, all data that comes after this just get destroyed.

I sort the array like this: ID, USERNAME, PING, IDENTIFIERNUMBER, IP

Example by the sorting output with username with one space in it:


ID: 0, USERNAME: Moritz, PING: 0, IDENTIFIERNUMBER: ID123456789, IP: 127.0.0.1:1234

ID: 1, USERNAME: August, PING: Jones, IDENTIFIERNUMBER: 46, IP: ID123456789

ID: 127.0.0.1:1234, USERNAME: 2, PING: Miller, IDENTIFIERNUMBER: 46, IP: ID123456789


How do I get the information correctly out of the string?

Just forgot to say:

The string begins with: --------------------------------- in a not countable order. So it can be like 10 characters or 12. The string ends with:

 (8 users in total)

The regex methode looks good. I only need to filter out the other characters.

--------------------------------- 0 127.0.0.1:1234 0 ID123456789(OK) Moritz 1 127.0.0.1:1234 46 ID123456789(OK) August Jones 2 127.0.0.1:1234 46 ID123456789(OK) Miller (7 users in total)

我的socket_recvfrom的原始输出是: p>

ID IP PING IDENTIFIERNUMBER USERNAME


0 127.0.0.1:1234 0 ID123456789 Moritz p>

1 127.0.0.1:1234 46 ID123456789 August Jones p >

2 127.0.0.1:1234 46 ID123456789米勒 p>


这是一个包含所有这些信息的单个字符串 包含信息之间的空格。 所有键都可以更长或更短。 p>

我的问题: p>

当我 preg_split(“/ \ s + /”) code >它,然后我得到一个有可用数据的好数组,但当用户名包含空格时,它会为此创建第二个索引。 不好,这之后的所有数据都被破坏了。 p>

我按如下方式对数组进行排序:ID,USERNAME,PING,IDENTIFIERNUMBER,IP p>

使用带有一个空格的用户名的排序输出示例: p>


ID:0,USERNAME:Moritz,PING:0,IDENTIFIERNUMBER:ID123456789,IP: 127.0.0.1:1234

ID:1,USERNAME:August,PING:Jones,IDENTIFIERNUMBER:46,IP:ID123456789 p>

ID:127.0。 0.1:1234,USERNAME:2,PING:Miller,IDENTIFIERNUMBER:46,IP:ID123456789 p>


如何正确地从字符串中获取信息?

忘了说: p>

字符串以:开头---------------- ----------------- code>以不可数的顺序。 所以它可以是10个字符或12个。 字符串以: p>

 (总共8个用户)
  code>  pre> 
 
  

正则表达式方法看起来不错。 我只需要过滤掉其他字符。 p>

  --------------------------  ------- 0 127.0.0.1:1234 0 ID123456789(OK)Moritz 1 127.0.0.1:1234 46 ID123456789(OK)August Jones 2 127.0.0.1:1234 46 ID123456789(OK)Miller(共7位用户)  
  code>  pre> 
 
 

上一个问题: https ://www.regex101.com/r/wP8cW1/1 p> div>

You may use regex

(?P<ID>\d+)\s+(?P<IP>\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}:\d+)\s(?P<PINGR>\d+)\s(?P<IDENTIFIERNUMBER>ID\d+)(\(OK\))?(?P<USERNAME>(\s[A-z]\w+)+)

MATCH 1
ID  [0-1]   `0`
IP  [2-16]  `127.0.0.1:1234`
PINGR   [17-18] `0`
IDENTIFIERNUMBER    [19-30] `ID123456789`
USERNAME    [31-37] `Moritz`

MATCH 2
ID  [39-40] `1`
IP  [41-55] `127.0.0.1:1234`
PINGR   [56-58] `46`
IDENTIFIERNUMBER    [59-70] `ID123456789`
USERNAME    [71-83] `August Jones`

MATCH 3
ID  [85-86] `2`
IP  [87-101]    `127.0.0.1:1234`
PINGR   [102-104]   `46`
IDENTIFIERNUMBER    [105-116]   `ID123456789`
USERNAME    [117-123]   `Miller`

Demo and explanation

Do you alredy try explode the string by new lines ??

test this code.

$str = '0 127.0.0.1:1234 0 ID123456789 Moritz
      1 127.0.0.1:1234 46 ID123456789 August Jones
      2 127.0.0.1:1234 46 ID123456789 Miller';

$lines = array_filter(explode("
", $str)); 

    foreach ($lines as $value) {
        $t[] = preg_split("/\s+/", trim($value));
    }

Now in the var $t you have a usefull data.
