php - 如何将此字符串拆分为数组？

Question

所以我有一些查询游戏服务器的数据，我需要找到一种方法来提取这些信息，以便它可以在我的网站上使用。

# 7 "player1" 1156 STEAM_0:4:00100365   0 09:52   84    3 175.77.234.241:27505
# 8 "player2" 1149 STEAM_0:0:39163243  2 14:05   52    0 109.175.131.239:65423
# 9 "player " 1159 STEAM_0:0:162  31 07:19   45    0 78.1.126.130:27025
#10 "gameer123" 1146 STEAM_0:0:701135   4 16:41   94    0 191.200.0.100:14097

上面几行的格式是:"id""name""userid""uniqueid""frag""time""ping""loss""adr"

我如何提取这些信息并将其转换成一个数组，这样我就有了这样的东西

[0] => Array
    (
        [Id] => 0
        [Name] => Player0
        [Frags] => 0
        [Time] => 50856
        [Uniqueid] => STEAM_0:4:001534362
    )

[1] => Array
    (
        [Id] => 0
        [Name] => Player1
        [Frags] => 4
        [Time] => 1447
        [Uniqueid] => STEAM_0:4:00100365
    )

顺便说一句，我只需要玩家姓名、片段、时间和唯一 ID。

这是另一种 RegEx 方法，使用命名模式，这些模式直接回收到干净的最终数组的数组键中。您可以将此处建议的任何 RegEx 模式集与以下解决方案一起使用，只需添加 (?<Keyname>...)在每个模式的括号的开头进行命名。

$data = <<<EOL
# 7 "player1" 1156 STEAM_0:4:00100365   0 09:52   84    3 175.77.234.241:27505
# 8 "player2" 1149 STEAM_0:0:39163243  2 14:05   52    0 109.175.131.239:65423
# 9 "player" 1159 STEAM_0:0:162  31 07:19   45    0 78.1.126.130:27025
#10 "gameer123" 1146 STEAM_0:0:701135   4 16:41   94    0 191.200.0.100:14097
EOL;

/* Matching the source data with named patterns */

preg_match_all('#(?<Id>\d+)\s+"(?<Name>[[:alnum:]]+)"\s+\d+\s+(?<Uniqueid>STEAM_[0-9_:]+)\s+(?<Frags>\d+)\s+(?<Time>[\d:]{5})#m', $data, $fields, PREG_SET_ORDER);

/* Cleaning up the numeric keys from RegEx matches */

foreach($fields as $num=>$set) {
    $fields[$num] = array_diff_key($set, array_flip( array_filter( array_keys($set), 'is_int')) );
}

print_r($fields);

结果:

Array
(
    [0] => Array
        (
            [Id] => 7
            [Name] => player1
            [Uniqueid] => STEAM_0:4:00100365
            [Frags] => 0
            [Time] => 09:52
        )

    [1] => Array
        (
            [Id] => 8
            [Name] => player2
            [Uniqueid] => STEAM_0:0:39163243
            [Frags] => 2
            [Time] => 14:05
        )

    [2] => Array
        (
            [Id] => 9
            [Name] => player
            [Uniqueid] => STEAM_0:0:162
            [Frags] => 31
            [Time] => 07:19
        )

    [3] => Array
        (
            [Id] => 10
            [Name] => gameer123
            [Uniqueid] => STEAM_0:0:701135
            [Frags] => 4
            [Time] => 16:41
        )

)

请注意，我已经从 "player " 中删除了源数据的第三行进入"player" ，假设这是一个错字。如果玩家名称有其他字符，请将它们添加到:(?<Name>[[:alnum:] _-]+)等等

我将命名模式 int-key-cleaner 回收到一个函数中，以防有人需要经常使用。

    /* In place of the foreach-loop above, use: */

$fields = remove_int_keys_pma($fields);

    /* And stick these two functions somewhere. */

/* Remove integer keys from preg_match_all sets. (Must use PREG_SET_ORDER.) */

function remove_int_keys_pma($array) {
    foreach($array as $k=>$set) {
        $array[$k] = remove_int_keys($set);
    }
    return $array;
}

/* Remove integer keys from an array. */

function remove_int_keys($array) {
    return array_diff_key($array, array_flip( array_filter( array_keys($array), 'is_int')) );
}
