Example usage

// song.php
$text = <<<SONG
D                      G          D
Be thou my vision, oh Lord of my heart
A                          G              A
Naught be all else to me, save that thou art
G             D/F♯       Bm         G  A
Thou my best thought, by day or by night
Bm          F♯m            G     A    D
Waking or sleeping, thy presence my light

D                        G       D
High King of heaven, my victory won
A                          G              A
May I reach heaven's joys, O bright heaven's sun
G             D/F♯      Bm       G   A
Heart of my own heart, whatever befall
Bm          F♯m        G    A   D
Still be my vision, O ruler of all
