Step by Step Guide to Building a Heroku API Integration in PHP

Introduction

Hey there, fellow developer! Ready to supercharge your PHP projects with Heroku's powerful API? You're in the right place. We'll be using the nifty php-heroku-client package to make our lives easier. Let's dive in and get your Heroku integration up and running in no time!

Prerequisites

Before we jump into the code, make sure you've got:

• A PHP environment (you're a pro, so I'm sure you've got this covered)
• Composer installed (because who doesn't love dependency management?)
• A Heroku account and API key (if you don't have one, go grab it real quick)

Installation

First things first, let's get that php-heroku-client installed. Fire up your terminal and run:

composer require heroku/heroku-api

Easy peasy, right?

Authentication

Now, let's get you authenticated. Grab your Heroku API key and let's set things up:

use Heroku\Client as HerokuClient;

$heroku = new HerokuClient(['api_key' => 'your-api-key-here']);

Boom! You're in. Let's start doing some cool stuff.

Basic API Operations

Listing Apps

Want to see all your Heroku apps? Here's how:

$apps = $heroku->get('/apps');
foreach ($apps as $app) {
    echo $app['name'] . "\n";
}

Creating a New App

Feeling creative? Let's birth a new app:

$newApp = $heroku->post('/apps', ['name' => 'my-awesome-app']);
echo "Created app: " . $newApp['name'];

Retrieving App Info

Need the deets on a specific app? Got you covered:

$appInfo = $heroku->get('/apps/my-awesome-app');
print_r($appInfo);

Advanced Operations

Scaling Dynos

Time to beef up your app? Scale those dynos:

$heroku->patch('/apps/my-awesome-app/formation/web', [
    'quantity' => 2,
    'size' => 'standard-2x'
]);

Managing Add-ons

Let's add some superpowers to your app:

$heroku->post('/apps/my-awesome-app/addons', [
    'plan' => 'heroku-postgresql:hobby-dev'
]);

Deploying Code

Push that code to Heroku like a boss:

$heroku->post('/apps/my-awesome-app/builds', [
    'source_blob' => [
        'url' => 'https://github.com/your-repo/archive/master.tar.gz'
    ]
]);

Error Handling

Nobody's perfect, so let's catch those errors:

try {
    $result = $heroku->get('/non-existent-endpoint');
} catch (\Heroku\Exception\RequestException $e) {
    echo "Oops! " . $e->getMessage();
}

Best Practices

• Keep an eye on those rate limits. Heroku's generous, but don't push it.
• Cache responses when you can. Your API will thank you.

Example Project: Simple Heroku Dashboard

Let's put it all together in a mini dashboard:

<?php
require 'vendor/autoload.php';

use Heroku\Client as HerokuClient;

$heroku = new HerokuClient(['api_key' => 'your-api-key-here']);

$apps = $heroku->get('/apps');

echo "<h1>My Heroku Apps</h1>";
echo "<ul>";
foreach ($apps as $app) {
    echo "<li>{$app['name']} - {$app['web_url']}</li>";
}
echo "</ul>";

Conclusion

And there you have it! You're now equipped to harness the power of Heroku's API in your PHP projects. Remember, this is just scratching the surface. There's a whole world of Heroku API goodness waiting for you to explore.
