 What are we going to learn today?[edit]
- Today in class we will start learning about collections and arrays. THESE ARE DIFFERENT.
- If using weapons as array examples offends you, please use this potion list as an alternative.
<?php
# this file is used to teach the VERY BASICS of arrays in PHP
$shop_items = array(
"short sword",
"dagger",
"flail",
"morning star",
"spear",
"long bow",
"crossbow",
"long sword",
"two handed sword",
"scimitar",
"short bow",
"staff",
"club"
);
# This creates a very simple array.
# We can perform some different operations on this array:
# count the items in the array:
echo "<p>Welcome to our shop. We sell many things for adventurers </p>";
echo "<p>==========================================</p>";
# let's list our inventory:
for ($i = 0; $i < count($shop_items); $i++)
{
echo $i . " - $shop_items[$i] <br />";
}
?>
Below we have an example if an associative array:
<?php
# this file is used to teach the VERY BASICS of arrays in PHP
$shop_items = array(
"short sword" =>"10",
"dagger" => "2",
"flail" => "12",
"morning star" => "15",
"spear" => "25",
"long bow" => "15",
"crossbow" => "20",
"long sword" => "21",
"two handed sword" => "30",
"scimitar" => "18",
"short bow" => "15",
"staff" => "5",
"club" => "2"
);
# This creates a very simple array.
# We can perform some different operations on this array:
# count the items in the array:
echo "<p>Welcome to our shop. We sell many things for adventurers </p>";
echo "<p>==========================================</p>";
# let's list our inventory:
foreach ($shop_items as $i => $cost_of_item)
{
echo $i . " costs $cost_of_item <br />";
}
?>

 As a computer scientist, you have:[edit]
- Confidence in dealing with complexity
- Persistence in working with difficult problems
- Tolerance for ambiguity
- The ability to deal with open-ended problems
- The ability to communicate and work with others to achieve a common goal or solution
