从文章PHP, Once The Web’s Favorite Programming Language, Is On The Wane看到on the wane的说法.

becoming less; fading away. Her influence in on the wane, but she is still the boss.

有兴趣可以看看上面这篇文章的评论区大家的撕逼:D 从数据上来看PHP还是当今的主流.

查了一下才知道wane就是衰退(期)的意思… 词汇量捉急.

wane:

vi: 衰落; （月）亏，缺; 结束; 变暗淡

n: 衰退; 衰退期; 月亏期; 缺角方木

  1. The moon is on the wane.
    月亮渐亏.
  2. When did the empire begin to wane?
    那个帝国何时开始衰落的?
  3. Her enthusiasm for him was beginning to wane.
    她对他的热情在开始减退.

From iciba - wane.
