How to add an element to the end of an array?

To add an element to the end of an array in PHP, you can use the [] notation or the array_push() function. Here’s how you can do it:

1. Using [] notation:
   You can use the square bracket notation with empty brackets [] to append a new element to the end of an array. This method is commonly used and provides a concise way to add elements.

$fruits = ["apple", "banana", "orange"];
$fruits[] = "mango"; // Add "mango" to the end of the array

print_r($fruits);

Output:

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

2. Using array_push() function:
   The array_push() function allows you to add one or more elements to the end of an array. It takes the array as the first parameter, followed by the element(s) to be added.

$fruits = ["apple", "banana", "orange"];
array_push($fruits, "mango"); // Add "mango" to the end of the array

print_r($fruits);

Output:

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

Both methods will result in adding the new element to the end of the array. Choose the method that suits your coding style and requirements.
