php正则表达式应用之提炼歌词
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

"; 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——
