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。

我找不到合适的reg exps。当这样做时,我需要采用id,时间和字幕变量。并且当打印时,不存在array()s等等必须与原始文件中的相同打印。

我的意思是我必须打印出来;

$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,您可以循环遍历subs数组或通过数组偏移量访问它们:

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

通过循环显示所有潜艇并显示它来显示所有潜艇:

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,因为你的$ 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',
...
)

你的正则表达式不会匹配任何这些元素。

如果您的目的是将整个文件读入一个长字符串的内存中,则使用file_get_contents将整个文件内容转换为一个字符串。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,并做适当的事情。很明显,您可能还需要一些逻辑来确保以正确的顺序获取值(id,然后是时间范围,然后是文本)。

使用array_chunk()file()数组分组为4个块,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 />';
}

答案 3 :(得分:0)

我创建了一个类来将.srt文件转换为数组。 数组的每个条目都具有以下属性:

  • id:表示字幕(2)
  • 的id的数字
  • start:float,以秒为单位的开始时间(24.443)
  • end:float,以秒为单位的结束时间(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)
  • 持续时间:字幕的持续时间,以ms(3204)为单位
  • text:副标题的文字( Peacocks统治过Gongmen City。

可以通过使用php换行符来完成。 我可以成功做到 让我显示我的代码

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

此处$ movie-> SRT是在此问题中发布格式的字幕。 如我们所见,每次空间是两条新线, 希望你得到答案。

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:

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Java中已经存在的dateFormat.parse,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 subs

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