1
00:00:00,180 --> 00:00:04,250
We're going to use the Slim
skeleton to set up our application.

2
00:00:04,250 --> 00:00:09,833
Let's run, composer create-project

3
00:00:09,833 --> 00:00:15,747
slim/slim-skeleton php_rest_api,

4
00:00:15,747 --> 00:00:19,530
as the name of our project.

5
00:00:23,328 --> 00:00:27,151
Now we can cd into php_rest_api.

6
00:00:30,428 --> 00:00:33,460
Now I can open these files in an editor.

7
00:00:33,460 --> 00:00:40,026
In our public folder, we have
an .htaccess file and our index.php file.

8
00:00:40,026 --> 00:00:43,114
So let's try running our application.

9
00:00:43,114 --> 00:00:48,204
In MAMP,
I'll go to Preferences > Web Server,

10
00:00:48,204 --> 00:00:55,546
and select Documents > php_rest_api,
and our public directory.

11
00:00:57,297 --> 00:00:59,116
We can then start the servers.

12
00:01:00,985 --> 00:01:04,000
Great, our application is running.

13
00:01:04,000 --> 00:01:06,030
Let's start setting things up.

14
00:01:06,030 --> 00:01:07,850
Let's start in the settings file.

15
00:01:09,360 --> 00:01:11,720
We're going to be working
in our src directory.

16
00:01:12,850 --> 00:01:18,137
In this settings file, I'm going to
be adding API and database settings.

17
00:01:18,137 --> 00:01:21,153
These could be set using
environment variables,

18
00:01:21,153 --> 00:01:23,676
so check the notes for more information.

19
00:01:23,676 --> 00:01:25,501
First, I'll add the API.

20
00:01:28,894 --> 00:01:34,096
Api is going to equal

21
00:01:34,096 --> 00:01:39,271
version, v1,

22
00:01:39,271 --> 00:01:46,062
and the base URL,
This is going to be our localhost.

23
00:01:51,993 --> 00:01:59,402
Now I can add the SQLite database, db,

24
00:02:02,977 --> 00:02:08,118
And for a SQLite database, I need the dsn,

25
00:02:09,162 --> 00:02:14,534
Which will be sqlite, And the database.

26
00:02:16,398 --> 00:02:19,759
I'm gonna put this database
in the current src directory.

27
00:02:20,787 --> 00:02:26,852
And it's named course_reviews.db.

28
00:02:28,680 --> 00:02:32,760
You can download the database that I've
supplied that has some test data in it

29
00:02:32,760 --> 00:02:33,780
already.

30
00:02:33,780 --> 00:02:36,070
I'm gonna move mine to this src directory.

31
00:02:45,160 --> 00:02:49,630
As you can see,
I have the course_reviews.db.

32
00:02:49,630 --> 00:02:54,916
Now I'm ready to add the API and database
dependencies to my dependency container so

33
00:02:54,916 --> 00:02:59,094
that I can access these dependencies
throughout my application.

34
00:03:04,586 --> 00:03:06,878
Let's give us some space,
and this will be our API.

35
00:03:10,542 --> 00:03:16,083
We'll say $container, ['api'].

36
00:03:24,092 --> 00:03:29,798
I'm going to set $api
= $c->get('settings'),

37
00:03:32,825 --> 00:03:35,416
And the api settings.

38
00:03:35,416 --> 00:03:37,800
For right now,
I'm just going to return the api.

39
00:03:41,995 --> 00:03:46,250
Remember that we need to add the semicolon
after each of these containers.

40
00:03:50,018 --> 00:03:54,321
Now I need a container for
PDO to connect to my SQLite database.

41
00:03:57,378 --> 00:03:58,563
We'll call this db.

42
00:04:04,950 --> 00:04:10,602
And we'll set our $db
= $c->get('settings'),

43
00:04:13,163 --> 00:04:14,460
And our database settings.

44
00:04:16,430 --> 00:04:18,130
Then we'll create a new PDO.

45
00:04:22,577 --> 00:04:26,524
And we'll use $db['dsn'],

46
00:04:29,069 --> 00:04:35,840
And then a colon, and
then our $db['database'].

47
00:04:35,840 --> 00:04:41,870
I'm also going to add some PDO attributes.

48
00:04:41,870 --> 00:04:46,270
These are things like error mode and
default modes.

49
00:04:46,270 --> 00:04:48,320
Check the notes for more information.

50
00:04:48,320 --> 00:04:51,245
Then we'll return the $pdo.

51
00:04:52,700 --> 00:04:57,930
The last thing that I need to set up
is autoloading for our own classes.

52
00:04:57,930 --> 00:05:05,400
Open composer.json, if you scroll down,
you'll see the autoload-dev.

53
00:05:05,400 --> 00:05:07,560
This is for tests.

54
00:05:07,560 --> 00:05:12,610
We'll copy this section, and
we'll change it to autoload.

55
00:05:12,610 --> 00:05:16,834
And instead of Tests,
we're going to say App, and

56
00:05:16,834 --> 00:05:20,650
our app lives in our src directory.

57
00:05:20,650 --> 00:05:25,290
Before these changes will take effect,
we need to run composer update.

58
00:05:26,700 --> 00:05:32,380
From within the php_rest_api directory,
we run, composer update.

59
00:05:34,508 --> 00:05:39,018
Now that we've added our settings,
dependencies, and autoloader,

60
00:05:39,018 --> 00:05:41,820
we're ready to build our API.

61
00:05:41,820 --> 00:05:45,150
Since an API is all about sharing data,

62
00:05:45,150 --> 00:05:48,580
the first thing we need
to do is access that data
