PHP regular expression application to extract lyrics_PHP tutorial

前几天看了下百度音乐盒的功能，发现有歌词功能

　　这里的歌词一般都是LRC格式的，是有时间的，如果想用作文本没有时间的话，文本里面的时间段就会成为了干扰障碍。

　　下面是一首歌的Lrc歌词

[ti:听说][ar:刘若英][al:我的失败与伟大][by:活在当下][00:01.22]刘若英 - 听说[00:03.79]专辑名称：听说？[00:06.73]作词：葛大为　作曲：林健华[00:09.74][00:10.79]lrc制作:卜超  QQ:6313827[00:25.13][00:27.08]听说　你身边有新面孔[00:32.04]听说　你不再寂寞[00:35.33]听说　你提起我[00:38.73]我过得不错　忙碌中还有感动[00:45.38]尝试爱过几个人　面对爱　也诚实许多[00:52.86]只能被听说　安排着[00:56.91]关于你我的　对的或错的[00:60.00]两个人　曾经相似的　却以为都变了[01:06.18]只能靠听说　各自爱着[01:10.24]不需要证明　当时决定是错的[01:13.31]想着联络　不如心底远远问候[01:19.56]最美丽　莫过于听说你　还回忆[01:24.80]其实我也感激　当我听说你还相信爱情[01:45.82][01:47.83]听说　我巷口你常经过[01:52.76]听说　你厌倦寂寞[01:56.10]听说　你问候我[01:59.52]我过得不错　忙碌中还有感动[02:06.04]尝试爱过几个人　面对爱　也诚实许多[02:52.11][02:12.94][02:52.67][02:13.35]只能被听说　安排着[02:56.63][02:17.26]关于你我的　对的或错的[02:59.77][02:20.32]两个人　曾经相似的　却以为都变了[03:06.11][02:26.48]只能靠听说　各自爱着[03:10.07][02:30.56]不需要证明　当时决定是错的[03:13.10][02:33.62]想着联络　不如心底远远问候[03:19.31][02:39.88]最美丽　莫过于听说你　还回忆[03:24.58][02:45.12]其实我也感激　当我听说你还相信爱情[03:33.66][03:36.56]听说　我身边有新面孔[03:42.53]听说　你祝福了我[03:52.39][03:53.93]lrc制作:卜超  QQ:6313827　　这里的时间段很有规律，一般以“[”开头以“]”结尾，有重复的时候就会出现两段时间段。第一时间想到了正则表达式，于是就用正则表达式写了如下的程序

                                 
";            preg_match_all("/][^[].*+/",$contents,$array);            $numArray = count($array[0]);            for($i = 0;$i";            }            echo "

这是处理后的歌词记录

";            echo $contents2;            echo "

这是未处理的歌词记录

";            echo "
";            echo "

";            print_r($array);            echo "

";        ?>   
　　于是乎，终于看见一线完美的喜悦——

There are many things that can only be heard and arranged. What is right or wrong about you and me? Two people who were once similar but thought they have changed can only rely on hearing that they are in love. There is no need to prove that the decision at that time was wrong. It is better to think about contact. The most beautiful greeting from far away in my heart is to hear that you still remember me. In fact, I am also grateful. When I heard that you still believed in love, I heard that you often passed by me in the alley. I heard that you were tired of loneliness. I heard that you greeted me. I am doing well. I am still busy. I have been moved and tried to love several people. I am also honest in the face of love. Many people can only be heard and heard about what is right or wrong about you and me. Two people who were once similar but thought they have changed can only rely on hearing that each of them loves each other without proof. The decision was wrong at that time, thinking that contact is not as good as greetings from a distance in my heart. The most beautiful thing is to hear that you still remember me. In fact, I am also grateful. When I heard that you still believed in love, I heard that there are new faces around me, and I heard that you blessed me. lrc production: Bu Chao QQ: 6313827 This is an unprocessed lyrics record array ([0] = & gt; Array ([0] = & gt;] [1] = & gt;] [2] = & gt;] [3] = & gt;] [4] => ] Liu Ruoying - Hearing and Listening [5] => ] Album name: Hearing and Listening [6] => ] Lyrics: Ge Dawei Composer: Lin Jianhua [7] => ] [8] = > ]lrc Produced by: Bu Chao QQ: 6313827 [9] => ] [10] => ]I heard there are new faces around you [11] => ]I heard you are no longer lonely [12] => ; ]I heard you mentioned me [13] => ]I’m doing well, I’m busy and I’m still touched [14] => ]I’ve tried to love a few people and I’m much more honest when it comes to love.
