我需要用 php 解析 srt 文件并用变量打印文件中的所有子文件。

我找不到正确的 reg exp。这样做时,我需要获取 id、时间和字幕变量。并且在打印时不能没有 array() 等,必须与原始文件中的打印相同。

我的意思是我必须像这样打印;

$number <br> (e.g. 1)
$time <br> (e.g. 00:00:00,074 --> 00:00:02,564)
$subtitle <br> (e.g. Previously on Breaking Bad...)

顺便说一句,我有这个代码。但它没有看到线条。它必须被编辑,但如何?

$srt_file = file('test.srt',FILE_IGNORE_NEW_LINES);
$regex = "/^(\d)+ ([\d]+:[\d]+:[\d]+,[\d]+) --> ([\d]+:[\d]+:[\d]+,[\d]+) (\w.+)/";

foreach($srt_file as $srt){

    preg_match($regex,$srt,$srt_lines);

    print_r($srt_lines);
    echo '<br />';

}

这是一个简短的状态机,用于逐行解析 SRT 文件:

define('SRT_STATE_SUBNUMBER', 0);
define('SRT_STATE_TIME',      1);
define('SRT_STATE_TEXT',      2);
define('SRT_STATE_BLANK',     3);

$lines   = file('test.srt');

$subs    = array();
$state   = SRT_STATE_SUBNUMBER;
$subNum  = 0;
$subText = '';
$subTime = '';

foreach($lines as $line) {
    switch($state) {
        case SRT_STATE_SUBNUMBER:
            $subNum = trim($line);
            $state  = SRT_STATE_TIME;
            break;

        case SRT_STATE_TIME:
            $subTime = trim($line);
            $state   = SRT_STATE_TEXT;
            break;

        case SRT_STATE_TEXT:
            if (trim($line) == '') {
                $sub = new stdClass;
                $sub->number = $subNum;
                list($sub->startTime, $sub->stopTime) = explode(' --> ', $subTime);
                $sub->text   = $subText;
                $subText     = '';
                $state       = SRT_STATE_SUBNUMBER;

                $subs[]      = $sub;
            } else {
                $subText .= $line;
            }
            break;
    }
}

if ($state == SRT_STATE_TEXT) {
    // if file was missing the trailing newlines, we'll be in this
    // state here.  Append the last read text and add the last sub.
    $sub->text = $subText;
    $subs[] = $sub;
}

print_r($subs);

结果:

Array
(
    [0] => stdClass Object
        (
            [number] => 1
            [stopTime] => 00:00:24,400
            [startTime] => 00:00:20,000
            [text] => Altocumulus clouds occur between six thousand
        )

    [1] => stdClass Object
        (
            [number] => 2
            [stopTime] => 00:00:27,800
            [startTime] => 00:00:24,600
            [text] => and twenty thousand feet above ground level.
        )

)

然后,您可以遍历 subs 数组或通过数组偏移量访问它们:

echo $subs[0]->number . ' says ' . $subs[0]->text . "\n";

要通过循环遍历每个子并显示它来显示所有子:

foreach($subs as $sub) {
    echo $sub->number . ' begins at ' . $sub->startTime .
         ' and ends at ' . $sub->stopTime . '.  The text is: <br /><pre>' .
         $sub->text . "</pre><br />\n";
}

这不会匹配,因为您的 $srt_file 数组可能如下所示:

Array
([0] => '1',
[1] => '00:00:00,074 --> 00:00:02,564',
[2] => 'Previously on Breaking Bad...'.
[3] => '',
[4] => '2',
...
)

您的正则表达式不会匹配任何这些元素。

如果您的意图是将整个文件读入一个长的 memory-hog-of-a-string,然后使用 file_get_contents 将整个文件内容放入一个字符串。然后使用 preg_match_all 获取所有正则表达式匹配。

否则,您可能会尝试遍历数组并尝试匹配各种正则表达式模式以确定该行是 id、时间范围还是文本并适当地执行操作。显然,您可能还需要一些逻辑来确保您以正确的顺序获取值(id,然后是时间范围,然后是文本)。

file()使用 将数组分组为 4 块array_chunk(),然后省略最后一个条目,因为它是一个空行,如下所示:

foreach( array_chunk( file( 'test.srt'), 4) as $entry) {
    list( $number, $time, $subtitle) = $entry;
    echo $number . '<br />';
    echo $time . '<br />';
    echo $subtitle . '<br />';
}

我做了一个类来将 .srt 文件转换为数组。数组的每个条目都具有以下属性:

  • id:一个数字,代表字幕的id(2)
  • start:float,以秒为单位的开始时间(24.443)
  • end:float,结束时间,以秒为单位(27.647)
  • startString:人类可读格式的开始时间 (00:00:24.443)
  • endString:人类可读格式的结束时间 (00:00:24.647)
  • duration: 字幕的时长,单位 ms (3204)
  • text:字幕的文字(孔雀统治公门城。

代码是php7:

你可以使用这个项目:https ://github.com/captioning/captioning

示例代码:

<?php
require_once __DIR__.'/../vendor/autoload.php';

use Captioning\Format\SubripFile;

try {
    $file = new SubripFile('your_file.srt');

    foreach ($file->getCues() as $line) {
        echo 'start: ' . $line->getStart() . "<br />\n";
        echo 'stop: ' . $line->getStop() . "<br />\n";
        echo 'startMS: ' . $line->getStartMS() . "<br />\n";
        echo 'stopMS: ' . $line->getStopMS() . "<br />\n";
        echo 'text: ' . $line->getText() . "<br />\n";
        echo "=====================<br />\n";
    }

} catch(Exception $e) {
    echo "Error: ".$e->getMessage()."\n";
}

样本输出:

它可以通过使用 php 换行符来完成。我可以成功让我展示我的代码

$srt=preg_split("/\\r\\n\\r\\n/",trim($movie->SRT));
            $result[$i]['IMDBID']=$movie->IMDBID;
            $result[$i]['TMDBID']=$movie->TMDBID;

这里 $movie->SRT 是在这个问题中发布格式的副标题。如我们所见,每个时间空间都是两个新行,希望您得到答案。

简单、自然、琐碎的解决方案

srt subs 看起来像这样,并由两个换行符分隔:

3
00:00:07,350 --> 00:00:09,780
The ability to destroy a planet is
nothing next to the power of the force

显然你想解析时间,使用dateFormat.parseJava中已经存在的时间,所以它是即时的。

class Sub {
    float start;
    String text;

    Sub(String block) {
        this.start = null; this.text = null;
        String[] lines = block.split("\n");
        if (lines.length < 3) { return; }

        String timey = lines[1].replaceAll(" .+$", "");
        try {
            DateFormat dateFormat = new SimpleDateFormat("HH:mm:ss,SSS");
            Date zero = dateFormat.parse("00:00:00,000");
            Date date = dateFormat.parse(timey);
            this.start = (float)(date.getTime() - zero.getTime()) / 1000f;
        } catch (ParseException e) {
            e.printStackTrace();
        }

        this.text = TextUtils.join(" ", Arrays.copyOfRange(lines, 2, lines.length) );
    }
}

显然,要获取文件中的所有潜艇

    List<Sub> subs = new ArrayList<>();
    String[] tt = fileText.split("\n\n");
    for (String s:tt) { subs.add(new Sub(s)); }
