Question

我有一个SRT文件目录，格式化：

8
00:00:45,879 --> 00:00:50,680
- Oh! Just leave me in the car with the window open a crack.
- That's the plan.

9
00:00:50,784 --> 00:00:54,117
I think it's nice we're doing something
Maggie will enjoy for once.

10
00:00:54,220 --> 00:00:58,350
Besides, I'm sure Storytown Village
is also fun for everyone...

我正在尝试将某些值放入MySQL数据库中，但我完全不知道如何使用正则表达式和php进行操作。

我想第一次（即00:00:50）进入“时间”，并将与该时间相关的任何文本行放入“文本”。

我甚至不能100％确定正则表达式是否可行，如果有更简单的方法可以做到这一点？

Answer 1

你的文本中有很多分隔符，所以我不会使用正则表达式。这是一个使用字符串操作的解决方案：

$lines = explode( "\n", $str);

for( $i = 0, $ii = count( $lines); $i < $ii; $i += 5) {
    $num = trim( $lines[ $i ]);

    list( $line2a, $line2b) = explode( ' --> ', $lines[ $i + 1]);
    list( $time1, $val1) = explode( ',', $line2a);
    list( $time2, $val2) = explode( ',', $line2b);

    $text1 = $lines[ $i + 2];
    $text2 = $lines[ $i + 3];

    echo "$num $time1 $val1 $time2 $val2\n$text1\n$text2\n\n";
}

请参阅the demo，了解哪些变量已分配给文件中的哪些值。

Answer 2

这种模式可行：

$pattern = '/([\d,:]+) --> [\d,:]+\n(.*\n.*)[^\n\n]/m';
$string = "
8
00:00:45,879 --> 00:00:50,680
- Oh! Just leave me in the car with the window open a crack.
- That's the plan.

9
00:00:50,784 --> 00:00:54,117
I think it's nice we're doing something
Maggie will enjoy for once.

10
00:00:54,220 --> 00:00:58,350
Besides, I'm sure Storytown Village
is also fun for everyone..."; //Your File Contents Here

preg_match_all($pattern, $string, $matches);
print_r($matches);

这将导致：

Array
(
[0] => Array
    (
        [0] => 00:00:45,879 --> 00:00:50,680

- 哦！只要让我在车窗外打开一个裂缝。 - 那就是计划。 [1] =＆gt; 00：00：50,784 - ＆gt; 00：00：54117 我觉得我们做的很好 Maggie将享受一次。 [2] =＆gt; 00：00：54,220 - ＆gt; 00：00：58350 此外，我很确定Storytown Village 对每个人来说都很有趣...... ）

[1] => Array
    (
        [0] => 00:00:45,879
        [1] => 00:00:50,784
        [2] => 00:00:54,220
    )

[2] => Array
    (
        [0] => - Oh! Just leave me in the car with the window open a crack.
 - That's the plan
        [1] => I think it's nice we're doing something
Maggie will enjoy for once
        [2] => Besides, I'm sure Storytown Village
is also fun for everyone..
    )

)

更新

foreach($matches[1] as $i => $data){
    $time = $data;
    $message = $matches[2][$i];
    mysqli_query("INSERT INTO Table (time,message) VALUES ('{$time}', '{$message}')");
}

如何使用正则表达式将srt文件插入mysql？
