Question

我的主题看起来像这样：

[9] 20:30:40 [SUCCESS] s-a24:1337
2
8.87
4038047
35320
4002727
[10] 20:30:40 [SUCCESS] s-d28:1337
2
2.64
4038047
37363
4000684
[11] 20:30:40 [SUCCESS] s-b29:1337
2
0.56
4038047
33066
4004981
[66] 20:30:42 [FAILURE] s-b25:1337 Timed out, Killed by signal 9
2
1.16
4038047
35274
[67] 20:30:42 [FAILURE] s-b30:1337 Timed out, Killed by signal 9

我需要创建一个匹配

的多维数组

成功/失败
描述符（s-a24，s-d28等）
后面的5行数字（可以是任意长度）

可能有0到5行（5行是SUCCESS）

我在正则表达式中绝对无能为力

我开始的是这个，它不起作用。

preg_match_all("/\[[0-9]+\](.*?)\[[0-9]+\]/",$output,$array);

Answer 1

我不确定一个简单的正则表达式是什么方式，特别是考虑到每条记录的数据变量计数。

那么，拆分字符串怎么样？

通过在每个换行符后面拆分它后跟一个“[”并在每个换行符中拆分每个结果，你可以用一个简单的正则表达式评估结果的每一行，并轻松添加数值数据，如果有的话是的。

Answer 2

这对我有用：

<?php

$str = '[9] 20:30:40 [SUCCESS] s-a24:1337
2
8.87
4038047
35320
4002727
[10] 20:30:40 [SUCCESS] s-d28:1337
2
2.64
4038047
37363
4000684
[11] 20:30:40 [SUCCESS] s-b29:1337
2
0.56
4038047
33066
4004981
[66] 20:30:42 [FAILURE] s-b25:1337 Timed out, Killed by signal 9
2
1.16
4038047
35274
[67] 20:30:42 [FAILURE] s-b30:1337 Timed out, Killed by signal 9';

preg_match_all("/^\[.*?\[(SUCCESS|FAILURE)\]\s(s\-\w\d{2}):1337.*?\n((.*\n){5})/m", $str, $matches, PREG_SET_ORDER);
//print_r($matches);
foreach ($matches as $match)
{
    echo $match[1] . "<br>\n";
    echo $match[2] . "<br>\n";
    echo $match[3] . "<br>\n";
}
?>

Answer 3

(\[\d*\].*\[(SUCCESS|FAILURE)\]\s(s-.{3}).*(\r[\d\.]+){0,5})

这个正则表达式应该可行。

Answer 4

快速又脏，但尝试尝试很有趣：

$success_pattern = '/\[(SUCCESS|FAILURE)\]/';
preg_match_all($success_pattern, $subject, $success_matches);

$descriptor_pattern = '/\[(SUCCESS|FAILURE)\]\s(.+?):/';
preg_match_all($descriptor_pattern, $subject, $descriptor_matches);

$numbers_pattern = '/\[.*?\n((\d+\.{0,1}\d*\n)+)/';
preg_match_all($numbers_pattern, $subject, $numbers_matches);

$output = array();
for($x = 0; $x < count($success_matches[0]); $x++) {
    $output[] = array(
        'success' => $success_matches[1][$x],
        'descriptor' => $descriptor_matches[2][$x],
        'numbers' => explode("\n", trim($numbers_matches[1][$x]))
    );
}

Answer 5

怎么样：

$string = '[9] 20:30:40 [SUCCESS] s-a24:1337
2
8.87
4038047
35320
4002727
[10] 20:30:40 [SUCCESS] s-d28:1337
2
2.64
4038047
37363
4000684
[11] 20:30:40 [SUCCESS] s-b29:1337
2
0.56
4038047
33066
4004981
[66] 20:30:42 [FAILURE] s-b25:1337 Timed out, Killed by signal 9
2
1.16
4038047
35274
[67] 20:30:42 [FAILURE] s-b30:1337 Timed out, Killed by signal 9
';

preg_match_all("/\[.*?\[(SUCCESS|FAILURE)\]\s+([^:]+):[^\n]+\n(?:([^[]+?)\n)?(?:([^[]+?)\n)?(?:([^[]+?)\n)?(?:([^[]+?)\n)?(?:([^[]+?)\n)?/m", $string, $matches, PREG_SET_ORDER);
print_r($matches);
