我需要用php解析srt文件并用变量打印文件中的所有子子。
我找不到正确的reg exps。执行此操作时,我需要采用ID,时间和字幕变量。并且当打印时,QU不是NO阵列()S或等。必须与在原始文件中相同。
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...)
.
顺便说一下我的代码。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 />';
}
. 解决方案
这是一个简单的状态机,用于按行解析SRT文件行:
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,您可以通过数组偏移量循环循环或访问它们:
echo $subs[0]->number . ' says ' . $subs[0]->text . "\n";
.
通过循环循环显示所有子句并显示它:
foreach($subs as $sub) {
echo $sub->number . ' begins at ' . $sub->startTime .
' and ends at ' . $sub->stopTime . '. The text is: <br /><pre>' .
$sub->text . "</pre><br />\n";
}
.
进一步读取:子领文本文件格式
其他提示
不匹配,因为您的$ 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Regex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内存的hog-of-string,则使用file_get_contents将整个文件内容置于一个字符串中。然后使用preg_match_all获取所有正则表达式匹配。
否则,您可能会尝试循环阵列,并尝试匹配各种正则表达式模式以确定该行是否是ID,时间范围或文本,并适当地进行事项。显然,您可能还希望某些逻辑以确保您以正确的顺序获取值(ID,然后是时间范围,然后文本)。
将file()
数组组分成4个使用 array_chunk()
,然后省略最后一个条目,因为它是一个空白行像这样:
foreach( array_chunk( file( 'test.srt'), 4) as $entry) {
list( $number, $time, $subtitle) = $entry;
echo $number . '<br />';
echo $time . '<br />';
echo $subtitle . '<br />';
}
. 我使一个类将.srt文件转换为数组。 数组的每个条目都具有以下属性:
- ID:表示字幕的ID(2)的数字
- 开始:浮动,开始时间为几秒钟(24.443)
- 结束:浮动,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,ms(3204)
- 文本:字幕的文本(孔雀统治在巩门市。)
代码是php7:
.<?php namespace VideoSubtitles\Srt; class SrtToArrayTool { public static function getArrayByFile(string $file): array { $ret = []; $gen = function ($filename) { $file = fopen($filename, 'r'); while (($line = fgets($file)) !== false) { yield rtrim($line); } fclose($file); }; $c = 0; $item = []; $text = ''; $n = 0; foreach ($gen($file) as $line) { if ('' !== $line) { if (0 === $n) { $item['id'] = $line; $n++; } elseif (1 === $n) { $p = explode('-->', $line); $start = str_replace(',', '.', trim($p[0])); $end = str_replace(',', '.', trim($p[1])); $startTime = self::toMilliSeconds(str_replace('.', ':', $start)); $endTime = self::toMilliSeconds(str_replace('.', ':', $end)); $item['start'] = $startTime / 1000; $item['end'] = $endTime / 1000; $item['startString'] = $start; $item['endString'] = $end; $item['duration'] = $endTime - $startTime; $n++; } else { if ($n >= 2) { if ('' !== $text) { $text .= PHP_EOL; } $text .= $line; } } } else { if (0 !== $n) { $item['text'] = $text; $ret[] = $item; $text = ''; $n = 0; } } $c++; } return $ret; } private static function toMilliSeconds(string $duration): int { $p = explode(':', $duration); return (int)$p[0] * 3600000 + (int)$p[1] * 60000 + (int)$p[2] * 1000 + (int)$p[3]; } }

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";
}
.

. 可以通过使用PHP线条断裂来完成。 我可以成功地做到 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']=$movie->TMDBID;
.
在这里$电影 - > srt是在这个问题中发布的格式的字幕。 正如我们所看到的,每次空间都是两行, 希望你得到回答。
