The array_push() is a built-in function that pushes elements into the array. It accepts the first parameter as an array in which a new element has to be added and in the second parameter it accepts a value or element that becomes part of the array.
Let’s create a variable that stores an array containing favorite countries.
$favoriteCountries = array("Germany","United Kingdom");
It has only two countries, to add more countries to the array we can use the array_push() function.
array_push($favoriteCountries, "South Korea", "Vietnam");
Here we passed the variable that stores the favorites countries array into the array_push() function as the first argument and two countries as the second and third arguments.
The array_push() function pushes the second and third arguments into the favorite countries array. To see the result we can use the print_r() function that prints the array.
print_r($favoriteCountries); // Output: Array (  => Germany  => United Kingdom  => South Korea  => Vietnam )
