Extract the lyrics of php Regular Expressions

I read the functions of Baidu music box a few days ago and found that there are lyrics.

Here, the lyrics are generally in LRC format and have time. If you want to use text without time, the time period in the text will become a disturbance obstacle.

Below is the Lrc lyrics of a song
