<?php
#array is a variable that holds multiple values
/*
Three types of arrays
- Indexed
- associative
- Multi-dimensional
*/
// Indexed array is the most common and easiest
$people = array('Kevin', 'Jeremy ', 'Sara');
$ids = array(23, 55, 12);
$cars = ['Honda', ' Toyota', 'Ford']; // also an array
//add to an array
$cars[3] = ' Audi';
// you can use empty brackets and it will be added to the last one
$cars[] = ' Chevy';

echo $ids[1];
echo $cars[1];
echo $cars[3];
echo $cars[4];
echo count($cars);
//you can also print the entire array
print_r($cars);
//to look at data type
echo var_dump($cars);
//Associative Arrays key pairs
$people1 = array('Kevin' => 35, 'Jeremy' => 23, 'Sara' => 19);
$ids1 = array(23 => 'Kevin', 55 => 'Jeremy', 12 => 'Sara');

echo $ids1[23];
//add to these types of arrays

//Multi-Dimensional Arrays aka an array within an array
