Scalability != performance. In fact, having to scale your architecture significantly with growth may be a symptom of a poor application performance. Yet, with the rise of cloud and the abundance of automation and container tools that simplify scalability aspect of your system, performance considerations are often pushed to the back row. Building systems for high performance is not easy. It requires a lot of considerations - from technology selection to design decisions. And "the cloud" does not magically solve those problems for you. In this talk I'll discuss common performance pitfalls across the stack and talk about useful techniques and examples that every application could benefit from.

PHP generators allow functions to behave like iterators by yielding values one at a time rather than building and returning an array all at once. Generators are automatically created when the yield keyword is used in a function. They implement the Iterator interface and can be used in foreach loops. Data and control flow can be passed into generators using the send() method to influence their behavior.
PHP is a server-side scripting language that can be embedded into HTML pages using PHP tags. When a PHP page is requested, the server will execute any PHP code and output the results. PHP allows variables, control structures, and functions to handle tasks like form processing, file uploads, and database access. Functions like file() can read file contents into an array, and files can be uploaded and moved using the $_FILES array and move_uploaded_file() function. PHP scripts can generate dynamic web page content on the server before sending the page to the client.
Mojolicious is a real-time web framework for Perl that provides a simplified single file mode through Mojolicious::Lite. It has a clean, portable, object oriented API without hidden magic. It supports HTTP, WebSockets, TLS, IPv6 and more. Templates can use embedded Perl and are automatically rendered. Helpers, sessions, routing and testing utilities are built in. The generator can create new app structures and components.
How to Create Login and Registration API in PHP.pdfAppweb Coders
In today’s article, we will explore the concept of REST API and delve into creating a login and registration system using these APIs. In the contemporary landscape of web development, establishing strong and secure authentication systems is of utmost significance. A highly effective approach is to construct a Login and Registration system through the utilization of REST APIs. This article aims to provide you with a comprehensive walkthrough, enabling you to construct a robust and efficient user authentication system from the ground up, harnessing the capabilities of REST architecture.
REST (Representational State Transfer) APIs act as a bridge between the client and the server, facilitating effective communication between them. They utilize HTTP requests to transfer data and are an optimal choice for constructing systems due to their stateless nature. REST APIs provide a seamless integration experience across a variety of platforms and devices.
Before we start coding, ensure you have a development environment set up. Install a web server (e.g., Apache), PHP, and a database (such as MySQL). Organize your project directory and create separate folders for PHP files, configurations, and assets.

UI5con 2024 - Boost Your Development Experience with UI5 Tooling ExtensionsPeter Muessig
The UI5 tooling is the development and build tooling of UI5. It is built in a modular and extensible way so that it can be easily extended by your needs. This session will showcase various tooling extensions which can boost your development experience by far so that you can really work offline, transpile your code in your project to use even newer versions of EcmaScript (than 2022 which is supported right now by the UI5 tooling), consume any npm package of your choice in your project, using different kind of proxies, and even stitching UI5 projects during development together to mimic your target environment.
Flutter is a popular open source, cross-platform framework developed by Google. In this webinar we'll explore Flutter and its architecture, delve into the Flutter Embedder and Flutter’s Dart language, discover how to leverage Flutter for embedded device development, learn about Automotive Grade Linux (AGL) and its consortium and understand the rationale behind AGL's choice of Flutter for next-gen IVI systems. Don’t miss this opportunity to discover whether Flutter is right for your project.
3. Memory Management in PHP
● Garbage collected
○ Reference counts
○ Happens after variable is unset, leave function
scope, or script ends, GC buffer is full
● All values are stored in hash tables of ZVAL structs
● Arrays are dynamically allocated by doubling the
size
● Much better in PHP 7 than 5.6
4. What are Iterators and Generators
Iterators are:
● An object that can be iterated over using a loop
● PHP has several built in the SPL
● Can create additional ones
● Special ones are the recursive & filter iterators
Generators are:
● A special kind of custom iterator
● Keywords & interfaces that allow you to define an
Iterator without having to create a class that
implements the interface
6. Generating many values: The object
<?php
namespace ArcIgTalk;
class User
{
public $_id;
public $firstName;
public $lastName;
public $email;
public $password;
public $phoneNumber;
}
7. Generating many values: Generate some values
<?php
...
for ($i = 0; $i < 1000000; $i++) {
$user = new User();
$user->_id = new ObjectID();
$user->email = $faker->email;
$user->password = $faker->password(12, 32);
$user->firstName = $faker->firstName();
$user->lastName = $faker->lastName;
$user->phoneNumber = $faker->phoneNumber;
$users[] = $user;
if ($i % 5000 === 0) {
$collection->insertMany($users);
$users = [];
}
}
14. Processing values: Why does it take so long?
● 3 nested loops
○ for ($up = 0; $up < 10000; $up++)
○ foreach ($provider->getPagedList($up) as $user)
○ foreach ($cursor as $data)
● O(n^3) or n*m*p
15. Processing values: What is going on?
<?php
namespace ArcIgTalk;
class Provider
{
public function getPagedList(int $page = 0, int $limit = 100): array
{
$cursor = $this->collection->find([],['limit' => $limit,'skip' => $page * $limit]);
$users = [];
foreach ($cursor as $data) {
$users[] = $this->createUserEntity($data->getArrayCopy());
}
return $users;
}
}
16. Processing values: What is going on?
<?php
$provider = new Provider(new Client("mongodb://datastore:27017"));
$emailLogPath = __DIR__ . '/../data/user.txt';
$emailLog = fopen($emailLogPath, 'w+');
for ($up = 0; $up < 10000; $up++) {
foreach ($provider->getPagedList($up) as $user) {
fwrite($emailLog, $user->email . "n");
}
}
fclose($emailLog);
17. Processing values: Make it faster
<?php
$provider = new Provider(new Client("mongodb://datastore:27017"));
$emailLogPath = __DIR__ . '/../data/user.txt';
$emailLog = fopen($emailLogPath, 'w+');
for ($up = 0; $up < 1000; $up++) {
foreach ($provider->getPagedList($up, 1000) as $user) {
fwrite($emailLog, $user->email . "n");
}
}
fclose($emailLog);
24. Processing values: It’s a bit slower
● 3 nested loops
○ for ($up = 0; $up < 10000; $up++)
○ foreach ($provider->getPagedList($up) as $user)
○ foreach ($cursor as $data)
● Effectively only 2
● O(n^2) or n*m
● Extra time for YIELD to go back & forth
