lrc歌词转srt，歌词格式转换

使用的laravel框架

/**
 * LRC 2 SRT
 */
public function getLrc2srt()
{
    //lrc文件的路径
    $sLrcFile = storage_path() . '/xqxayjr.lrc';
    $sLrcContent = iconv("EUC-CN", 'UTF-8', file_get_contents($sLrcFile));
    if (file_exists($sLrcFile)) {
        $sContent = lrc2srt($sLrcContent);
        if (file_put_contents(storage_path() . '/xqxayjr.srt', $sContent) !== false)
        {
            echo 'ok';
        }
    }
}复制代码

主要方法

public function lrc2srt($lrc) {
    $lrc = explode( "\n", $lrc );
    $srt = "";
    $lines = array();
    foreach ( $lrc as $lrcl ) {
        if ( preg_match( "|\[(\d\d)\:(\d\d)\.(\d\d)\](.+)|", $lrcl, $m ) ) {
            $lines[] = array(
                'time' => "00:{$m[1]}:{$m[2]},{$m[3]}0", // convert to SubRip-style time
                //front 设置字幕颜色
                'lyrics' => '<font color=#FFFFFF>' . trim($m[4]) . '</font>'
            );
        }
    }
    for ( $i = 0; $i < count( $lines ); $i++ ) {
        $n = $i + 1;
        $nexttime = isset( $lines[$n]['time'] ) ? $lines[$n]['time'] : "99:00:00,000";
        $srt .= "$n\n"
            .  "{$lines[$i]['time']} --> {$nexttime}\n"
            .  "{$lines[$i]['lyrics']}\n\n";
    }
    return $srt;
