让php将句子分解为单词

我可能误解了文档，但是当我编码时

explode(" ","here's a sentence",2 )

我最终...

Array
(
    [0] => here's
    [1] => a sentence with a few words in it
)

有没有办法让爆炸回来...

Array
(
    [0] => here's
    [1] => a
)

我试图让它获取给定的任何字符串的前两个单词并将它们放入一个数组中。

谢谢

你需要数组切片 https://www.php.net/manual/en/function.array-slice.php.

$result = array_slice(explode(" ","here's a sentence", 3), 0, 2);
