array_push() function

PHP array_push() is a built-in function used to insert new elements at the end of an array and get the updated array elements. The array_push() method takes a single element or an array of elements and appends it to the array.

Syntax:-

array_push(array,value1,value2...)

Parameters

An array parameter is required to which we will add the value.

The value1 parameter is also required, which is the value we will insert into the specified array.

The value2, value3, and so on are optional parameters. However, we need to pass those parameters if we want to add multiple values.

Example:-

<?php
    $nicname = ["Vijay", "Amit", "Dharmu"];

    array_push($nicname, "Ravi", "Rahul");

    echo "<pre>";
    print_r($nicname);
    echo "</pre>";
?>
