  $array = ['apple', 'banana', 'cherry'];
  print_r($array);

• Output: Outputs the array structure, showing keys and values.

• Example Output:
  

  Array
  (
      [0] => apple
      [1] => banana
      [2] => cherry
  )

2. Using var_dump()

• Purpose: var_dump() provides detailed information about the array, including types and lengths.
• Syntax:

  $array = ['apple', 'banana', 'cherry'];
  var_dump($array);

• Output: Detailed type and length information for each element.

• Example Output:
  

  array(3) {
    [0]=>
