In this example, we will take an array with two values. We will use array_push() function to append a value to this array.
PHP Program
<?php
$array1 = array("apple", "banana");
array_push($array1, "mango");
print_r($array1);

2. Push/Append Multiple Values to Array
In this example, we will push two values to a given array in a single statement using array_push() function.
PHP Program
<?php
$array1 = array("apple", "banana");
array_push($array1, "mango", "orange");
print_r($array1);

3. Print return value of array_push()
In this example, we will examine the return value of array_push() function.
We will take two elements in the array, and push two values to this array. The array must be updated and array_push() must return the new count of values which is four: Two previous values in array and two newly pushed values to array.
PHP Program
<?php
$array1 = array("apple", "banana");
$count = array_push($array1, "mango", "orange");
print_r($count);
