Is it best practice to define an array as an empty array before adding elements to it?

It is generally considered best practice to define an array as an empty array before adding elements to it. This helps to ensure that the array is initialized properly and avoids potential issues with undefined variables. By explicitly setting the array as empty before adding elements, you can also improve the readability and maintainability of your code. 

// Define an empty array before adding elements to it
$myArray = [];

// Add elements to the array
$myArray[] = "element1";
$myArray[] = "element2";
$myArray[] = "element3";

// Print the array to verify its contents
print_r($myArray);
