Arrays

Arrays keep related values in order and let code read values by index.

arrays.php

<?php
$scores = [82, 91, 76];
$bonus = ;
$firstScore = $scores[0];
$adjustedScore = $scores[1] + $bonus;

echo "first=" . $firstScore . "\n";
echo "adjusted=" . $adjustedScore . "\n";

<?php
$scores = [82, 91, 76];
$bonus = ;
$firstScore = $scores[0];
$adjustedScore = $scores[1] + $bonus;

echo "first=" . $firstScore . "\n";
echo "adjusted=" . $adjustedScore . "\n";

<?php
$scores = [82, 91, 76];
$bonus = ;
$firstScore = $scores[0];
$adjustedScore = $scores[1] + $bonus;

echo "first=" . $firstScore . "\n";
echo "adjusted=" . $adjustedScore . "\n";

array index Array indexes start at zero, so `$scores[0]` reads the first value.
