git clone git@github.com:patrickallaert/php-from-scratch-workshop.git workshopEdit your /etc/hosts and add:
::1 workshop.local
or, if you still live in the IPv4 era:
127.0.0.1 workshop.local
Now let's configure Apache with a VirtualHost:
<VirtualHost *:80>
ServerName workshop.local
DocumentRoot /path/to/workshop/web
<Directory /path/to/workshop>
Require all granted
AllowOverride all
</Directory>
</VirtualHost>
After restarting Apache, let's try the whole configuration and edit web/index.php and put the above:
<?= "Hello world" ?>Open http://workshop.local/, it should display: Hello world
In this workshop, we will create a skinny Twitter-like application made of two simple pages: a homepage showing a list of accounts and an account page showing the tweets for a specific account. For the sake of this workshop, we will first do this the dirty way and it will look like procedural PHP 3 code like some of us did 20 years ago ;-)
Some data are available in data/tweets.php as a big serialized array and should be considered as the database.
data/tweets.php:
<?php
return [
"Princess_Leia" => [
"name" => "Princess Leia",
"tweets" => [],
],
"Luke" => [
"name" => "Luke Skywalker",
"tweets" => [
[
"ts" => "2017-01-01T12:34:56+00:00",
"tweet" => "@Princess_Leia => I'm @Luke Skywalker and I'm here to rescue you!",
],
],
],
"Darth_Vader" => [
"name" => "Anakin Skywalker",
"tweets" => [
[
"ts" => "2017-01-13T16:00:00+00:00",
"tweet" => "@Luke, I am your father",
],
[
"ts" => "2016-06-06T16:23:00+00:00",
"tweet" => "Your powers are weak, old man.",
],
[
"ts" => "2016-05-10T19:00:00+00:00",
"tweet" => "I've been waiting for you, @Obi-Wan. We meet again, at last.",
],
],
],
"Obi-Wan" => [
"name" => "Obi-Wan \"Ben\" Kenobi",
"tweets" => [
[
"ts" => "2016-05-09T11:30:00+00:00",
"tweet" => "Blast. This is why I hate flying.",
],
[
"ts" => "2016-05-08T09:00:00+00:00",
"tweet" => "Your clones are very impressive. You must be very proud.",
],
[
"ts" => "2016-03-02T19:15:00+00:00",
"tweet" => "Use the Force, @Luke",
],
[
"ts" => "2016-01-01T14:00:00+00:00",
"tweet" => "@Luke, the Force will be with you",
],
],
],
];Example of what web/index.php and web/account.php could look like:
web/index.php:
<!DOCTYPE html>
<html>
<head>
<title>Twitter homepage</title>
</head>
<body>
<h1>Twitter homepage</h1>
<ul>
<?php foreach (require "../data/tweets.php" as $account => $data): ?>
<li>
<a href="account.php?username=<?= htmlentities($account)?>">
<?= htmlentities($data["name"]) ?>
</a>
</li>
<?php endforeach ?>
</ul>
</body>
</html>web/account.php:
<?php
$account = $_GET["username"];
$data = (require "../data/tweets.php")[$account];
?>
<!DOCTYPE html>
<html>
<head>
<title>Tweets from <?= htmlentities($data["name"])?> - @<?= htmlentities($account) ?></title>
</head>
<body>
<h1>Tweets from <?= htmlentities($data["name"])?> - @<?= htmlentities($account) ?></h1>
<ul>
<?php foreach ($data["tweets"] as $tweet): ?>
<li><?= htmlentities($tweet["tweet"]) ?> <span class="date">(<?= $tweet["ts"] ?>)</span></li>
<?php endforeach ?>
</ul>
</body>
