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

Introduction

Hey there, fellow developer! Ready to supercharge your PHP application with Fastly's powerful CDN capabilities? You're in the right place. In this guide, we'll walk through building a robust Fastly API integration that'll have you purging content, managing services, and handling configurations like a pro.

Prerequisites

Before we dive in, make sure you've got:

• A PHP environment (7.4+ recommended)
• Composer installed
• A Fastly account with an API key handy

Got all that? Great! Let's get our hands dirty.

Setting up the project

First things first, let's set up our project:

mkdir fastly-integration && cd fastly-integration
composer init
composer require fastly/fastly-php

Now, create a config.php file to store your API key:

<?php
define('FASTLY_API_KEY', 'your_api_key_here');

Basic API Connection

Let's establish a connection to Fastly:

<?php
require_once 'vendor/autoload.php';
require_once 'config.php';

$fastly = new Fastly\Fastly(FASTLY_API_KEY);

try {
    $account = $fastly->getAccount();
    echo "Connected to Fastly account: " . $account->getName();
} catch (Exception $e) {
    echo "Connection failed: " . $e->getMessage();
}

If you see your account name, you're golden!

Key Fastly API Operations

Purging Content

Need to clear that cache? Here's how:

$fastly->purgeAll('your_service_id');

Managing Services

Let's fetch all your services:

$services = $fastly->getServices();
foreach ($services as $service) {
    echo $service->getName() . "\n";
}

Handling Configurations

Time to get that active version:

$activeVersion = $fastly->getActiveVersion('your_service_id');
echo "Active version: " . $activeVersion->getNumber();

Error Handling and Logging

Always be prepared for the unexpected:

try {
    // Your Fastly API call here
} catch (Fastly\Exception\ApiException $e) {
    error_log("Fastly API error: " . $e->getMessage());
} catch (Exception $e) {
    error_log("Unexpected error: " . $e->getMessage());
}

Best Practices

• Respect rate limits: Fastly allows 1000 requests per hour. Keep track!
• Cache API responses when possible to reduce unnecessary calls.

Advanced Features

Streaming Logs

Set up log streaming like a boss:

$fastly->createLogginghoneycomb($serviceId, $activeVersion, [
    'name' => 'my_honeycomb_logs',
    'format' => '%h %l %u %t "%r" %>s %b',
    'dataset' => 'fastly_logs'
]);

Real-time Stats

Get those juicy real-time stats:

$stats = $fastly->getRealtimeStats('your_service_id');
echo "Hits: " . $stats->getData()->getHits();

Testing and Debugging

Don't forget to test! Here's a simple PHPUnit test to get you started:

public function testPurgeAll()
{
    $fastly = new Fastly\Fastly('test_api_key');
    $result = $fastly->purgeAll('test_service_id');
    $this->assertTrue($result);
}

Conclusion

And there you have it! You're now equipped to harness the power of Fastly in your PHP applications. Remember, the Fastly API is vast and powerful - we've just scratched the surface here. Keep exploring, keep building, and most importantly, keep optimizing!
