Beginner PHP Chapter 5 - Arrays - Code Block 2

<?php
 
$variable_name = array();  //Create a blank array, or empties an array.
 
$variable_name[] = 'valueA';  //Add a value to the array. If you do this again, it will add a second value to it, not replace the first one.
array_push($variable_name,'valueB'); //Another way to add a value to an array.
 
echo count($variable_name); //Displays the number of values in the array. This will input 2, because we added valueA and valueB to the array.
 
sort($variable_name); //Sorts the values within an array. There are several types of sorting, each with their own options. 
 
?>
