Lone Star PHP 2017 - More Than Just a Hammer

Learn to expand beyond just PHP to integrate other languages into both your personal skill set and the solutions you deliver.

In this talk we'll cover integrating JavaScript (frontend and backend via node) and how you can expand your current skill set to include this or any other language alongside PHP. The old saying, if all you have is a hammer everything looks like a nail, is very true so let's learn how to use a wrench and maybe a chainsaw!

Not only will this give you another tool in your tool belt, it will give you a greater understanding of development practices and the ability to on new jobs, new projects, and new challenges.

5. Maslow’s Hammer If all you have is a hammer, everything looks like a nail (paraphrased)
7. Why? Different projects have different needs
8. Why? Sockets Machine Learning
9. Why? Code Re-use X-App Communication
10. Why? Team Efficiencies Employee Retention Continuous Learning
12. When? New Projects New Modules
13. When? Internal Projects Dev Tools
15. Which? Feature isn’t Well Supported
16. Which? Experts Prefer a Different Language
17. Which? Libraries are Low Quality

37. Message Queues
38. Message Queues RabbitMQ Beanstalkd Redis Amazon SQS
39. Message Queues Send and receive messages
40. RPC / APIs
41. RPC / APIs JSON-RPC (client) —> (server) {"jsonrpc": "2.0", "method": "sendNotification", "params": {"id": 123, "sender_id": 1}, "recipient_id": 2, "message": "yo"} (client) <— (server) {"jsonrpc": "2.0", "result": 1, "id": 123}
42. RPC / APIs RESTful APIs
43. Message Queue + RPC
44. MQ + JSON-RPC Send callback queue in message
45. MQ + JSON-RPC
46. Databases / Redis
47. Databases / Redis Column | Type ----------------------------+--------------------- id | integer accepted_datetime | timestamp without time zone processed_datetime | timestamp without time zone
48. Databases / Redis > SUBSCRIBE notifications > PUBLISH notifications yo
49. EXAMPLE TIME!
51. MQ Example Message Queue
52. MQ Example yo app
53. MQ Example
54. MQ Example PHP-Amqplib https://packagist.org/packages/php-amqplib/php-amqplib amqplib https://www.npmjs.com/package/amqplib
56. MQ Example Install the RabbitMQ server on Mac OS $ brew install rabbitmq $ echo 'export PATH=/usr/local/sbin:$PATH' >>~/.bash_profile Append to your path $ rabbitmq-server Start the server
57. MQ Example Setup repo $ mkdir queueProject && cd queueProject
58. MQ Example { "require": { "php-amqplib/php-amqplib": ">=2.6.1" } } $ composer install Create and edit composer.json Install packages
59. MQ Example <?php require_once(__DIR__ . '/vendor/autoload.php'); use PhpAmqpLib\Connection\AMQPStreamConnection; use PhpAmqpLib\Message\AMQPMessage; Create and edit sendNotification.php
60. MQ Example … $connection = new AMQPStreamConnection( 'localhost', 5672, 'guest', 'guest'); $channel = $connection->channel(); $channel->queue_declare( 'notifications', false, true, false, false ); Edit sendNotification.php
61. MQ Example … $notification = [ 'id' => microtime(), 'sender_id' => Auth::user()->id, 'recipient_id' => $recipientUser->id, 'message' => 'yo' ]; $msg = new AMQPMessage(json_encode($notification)); $channel->basic_publish($msg, '', 'notifications'); Edit sendNotification.php
62. MQ Example $ php sendNotification.php Run our PHP script
63. MQ Example Check our queue for data $ rabbitmqadmin get queue=notifications +---------------+----------+---------------+------------------------------------------------- | routing_key | exchange | message_count | payload +---------------+----------+---------------+------------------------------------------------- | notifications | | 0 | {"sender_id":1,"recipient_id":2,"message":"yo"} +---------------+----------+---------------+-------------------------------------------------
64. MQ Example { "dependencies": { "amqplib": "0.5.1" } } $ npm install Create and edit package.json Install packages
65. MQ Example var amqp = require('amqplib/callback_api'); amqp.connect('amqp://localhost', function(err, conn) { … }); Create and edit processNotifications.js
66. MQ Example conn.createChannel(function(err, ch) { var queueName = 'notifications'; ch.assertQueue(queueName, {durable:true}); … }); Edit processNotifications.js
67. MQ Example console.log('[*] Waiting for notifications'); ch.consume(queueName, function(msg) { ch.ack(msg); console.log("[x] Received %s", msg.content.toString()); }); Edit processNotifications.js
68. MQ Example $ node processNotifications.js Run the node process [*] Waiting for notifications
69. MQ Example $ php sendNotification.php Run our PHP script Output from Node [*] Waiting for notifications [x] Received {"id":"0.36937600 1492376196", "sender_id": 1,"recipient_id":2,"message":"yo"}
71. Direct Exec Example Direct Execution
72. Direct Exec Example Setup repo $ mkdir directProject && cd directProject Create modules dir $ mkdir modules
73. Direct Exec Example <html><body> <h1>Make sure this field is required and says "yo"</h1> <input type="text" name="thing" id="thing" /> <input type="button" value="Validate!" onClick="validate()" /> <script type="text/javascript" src="modules/require.js" /> <script type="text/javascript" src="modules/index.js" /> </body></html> Create and edit index.html
74. Direct Exec Example
75. Direct Exec Example https://github.com/letorbi/smoothie Add CommonJS compatible loader to modules/require.js
76. Direct Exec Example exports.isValidYo = function(input) { if (input === 'yo') { return true; } return false; }; Create and edit modules/validator.js
77. Direct Exec Example function validate() { var validator = require('modules/validator'); if (validator.isValidYo(document.getElementById('thing').value)) { alert("They're good YOs Brent"); } else { alert("BAD!"); } } Create and edit index.js
78. Direct Exec Example
79. Direct Exec Example
80. Direct Exec Example
81. Direct Exec Example
82. Direct Exec Example var validator = require('./modules/validator'); if (validator.isValidYo(process.argv[2])) { console.log('good'); process.exit(0); } else { console.log('bad'); process.exit(1); } Create and edit nodeValidator.js
83. Direct Exec Example $ node nodeValidate.js "yo" good Run nodeValidate.js via Node $ node nodeValidate.js "fale" bad
84. Direct Exec Example <?php $input = escapeshellarg($argv[1]); exec('node ./nodeValidate.js ' . $input, $output, $result); if ($result === 0) { echo ""; } else { echo ""; } Create and edit phpValidate.php
85. Direct Exec Example $ php phpValidate.php "yo" Run phpValidate.php $ php phpValidate.php "fale"
