Creating the Catalog Array

[MUSIC] 0:00 [SOUND] In this project, 0:04 we're going to use an array to store all the information about our media items. 0:05 We'll have one array for the whole catalog. 0:09 The array will have multiple elements, one element for each item. 0:12 Then on the main catalog page, 0:16 we'll be able to loop through all the items using PHPs foreach command. 0:18 We still have more to cover about arrays before we can build the page entirely, but 0:23 lets open catalog.php and get a basic array in place. 0:27 At the very top of catalog.php, lets add some PHP code to create an array 0:32 We'll name this array, $catalog = array. 0:40 We'll add some values here. 0:50 Enclose our array. 0:59 We now have three elements here. 1:01 Design Patterns, Forrest Gump, and Beethoven. 1:04 The text for each element is enclosed in quotation marks. 1:11 There is a comma between each set of values. 1:14 If we were to put a comma within our value, 1:17 it would be treated as text, not as a separator between the elements. 1:19 We can put hard returns between each element to make it a little easier to tell 1:24 them apart. 1:28 You'll typically see large arrays written like this, 1:30 PHP doesn't care what you use for whitespace or indentation. 1:34 It just makes it easier for other developers to read your code. 1:39 Let's add the proper HTML for this page including the wrapper div. 1:42 Let's go down here. 1:46 First we're gonna add catalog 1:49 as part of our class because this is the catalog page. 1:53 We'll add a new div. 1:57 class="wrapper". 1:58 And we'll put our h1 tag Up here in our div. 2:07 Inside the wrapper div, 2:16 right below the h1 tag, let's list off our items in an unordered list. 2:17 When you're first starting, 2:22 I always recommend writing out the final HTML needed, and then working backwards to 2:23 figure out what PHP you'll need to use to generate that HTML. 2:27 So we're gonna need one unordered list with an opening and close. 2:33 And we're gonna do a list item. 2:39 And we need Item 1, list item Item 2, 2:43 and list item Item 3. 2:50 Okay, we can see now that we need to 2:55 include these list item tags within our foreach loop. 2:58 We don't need to include the unordered list 3:03 because there's only one pair of unordered list tags. 3:06 So let's replace the multiple LI tags with a foreach loop that displays one item for 3:09 each element in the array. 3:14 So we're gonna open up our php tag and we're gonna create a foreach. 3:16 Wanna see a foreach($catalog 3:22 as $item). 3:30 And then we're going 3:33 to echo out that item. 3:38 [INAUDIBLE]. Using concatenation we 3:43 do item, closing li tag, 3:48 and closing semicolon. 3:53 Let's make this a little bit easier to see. 3:58 Okay, and close out our PHP tag, and 4:03 then we'll remove these lines here. 4:08 So we've created a foreach loop for the catalog items. 4:14 And we've assigned each item to a variable item. 4:19 And then we've told it to print the item here below. 4:24 So let's take a look at this in the browser. 4:28 Okay, if we go to our Books page, we now see a list. 4:31 Design Patterns, Forrest Gump, and Beethoven, here in an unordered list. 4:37
