如何 return 使用 explode 反转数组

Question

所以 explode 函数将字符串分解成这样的数组：

$str = "Hello world. It's a beautiful day.";
print_r (explode(" ",$str));

结果将是：

Array ( [0] => Hello [1] => world. [2] => It's [3] => a [4] => beautiful [5] => day. )

但是如果我们需要对数组进行反向排序怎么办，那么预期的结果将如下所示：

Array ( [0] => day [1] => beautiful [2] => a  [3] => It's [4] => world. [5] => Hello  )

那么如何使用爆炸函数来做到这一点？

Answer 1

您可以像这样使用 array_reverse 以获得您想要的输出：

$str = "Hello world. It's a beautiful day.";
var_dump(array_reverse(explode(" ",$str)));

// Output
array(6) {
  [0]=>
  string(4) "day."
  [1]=>
  string(9) "beautiful"
  [2]=>
  string(1) "a"
  [3]=>
  string(4) "It's"
  [4]=>
  string(6) "world."
  [5]=>
  string(5) "Hello"
}
