分别用print_r()和var_dump()输出

以下数组：

$fruits = array("apple", "banana", "orange", "kiwi");

使用print_r()输出：

Array
(
    [0] => apple
    [1] => banana
    [2] => orange
    [3] => kiwi
)

使用var_dump()输出：

array(4) {
  [0]=>
  string(5) "apple"
  [1]=>
  string(6) "banana"
  [2]=>
  string(6) "orange"
  [3]=>
  string(4) "kiwi"
}

php利用sort()函数，对数组$a=array(20,34,12,54,64,43,7);分别实现print_r和var_dump两种方式升序输出

Sure! Here's the code:

$a = array(20, 34, 12, 54, 64, 43, 7);

// Sort the array in ascending order using sort() function
sort($a);

// Print the sorted array using print_r()
print_r($a);

// Print the sorted array using var_dump()
var_dump($a);

This will output:

Array
(
    [0] => 7
    [1] => 12
    [2] => 20
    [3] => 34
    [4] => 43
    [5] => 54
    [6] => 64
)
array(7) {
  [0]=>
  int(7)
  [1]=>
  int(12)
  [2]=>
  int(20)
  [3]=>
  int(34)
  [4]=>
  int(43)
  [5]=>
  int(54)
  [6]=>
  int(64)
}

I hope this helps!
