我试图通过比较一些短语并找到出现来找到一种在PHP中定义语义的方法，例如我有类似的东西
Array
(
[0] => Cats love Mouse Car Dog Fish
[1] => Pictures Cats Some Text Mouse
[2] => Game of thrones 2015 Series
[3] => Stark Series lannister John Game of thrones
[4] => Pop Rock David Bowie Music
[5] => David Great Lower Text Bowie
)
我期待输出
Array
(
[0] => Cats Mouse
[1] => Game of thrones Series
[2] => David Bowie
)
我该怎么办？
