How to Use array_push() Function in PHP
array_push() is used to push or add values into an array. This function treats the array as a pile or stack and pushes the values onto the end of the array.
For example :
$colors = array('red', 'blue', 'black');
array_push($colors, 'white', 'green');
Here, first we declared an array with some colors. Then with the array_push() function we added two more values to the array.
You can add as much values you like with this function.
