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

To add an element to the end of an array in PHP, you can use the array_push() function or simply use the [] syntax. Here are two methods for adding an element to the end of an array:

Using array_push()

$array = [1, 2, 3]; // Existing array
$newElement = 4;   // Element to be added

array_push($array, $newElement); // Adding element to the array

print_r($array); // Output: Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 )

Using [] syntax

$array = [1, 2, 3]; // Existing array
$newElement = 4;   // Element to be added

$array[] = $newElement; // Adding element to the array

print_r($array); // Output: Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 )

Both methods will add the element to the end of the array.
