Revisiting Evolution of PHP and Impact: From Controversy to Versatility

We will explore the journey of PHP, its unique characteristics, and its place in the evolving landscape of web development.

The Genesis of PHP: A Dynamic Toolset

PHP made its debut in 1994, thanks to Rasmus Lerdorf. However, the initial version of PHP was quite different from what we know today. Unlike most programming languages that start as complete entities, PHP evolved gradually. Initially, it served as a toolset designed to add dynamic functionality to websites using CGI (Common Gateway Interface), implemented in the C language. These tools were initially dubbed “Personal Home Page Tools” or PHP tools.

The CGI Era and PHP’s Emergence

During PHP’s inception, CGI was the primary means of serving dynamic content on the web. It entailed writing programs to serve web pages, incorporating dynamic elements. This allowed users to interact with websites, a novel concept at the time. While CGI remained relevant, PHP offered an alternative approach to creating dynamic web content, making it simpler and more accessible.

PHP’s Embeddability in HTML

One of PHP’s defining features is its seamless integration with HTML. This capability distinguished from other CGI tools like PERL. In a PHP script, you could embed code within an HTML document, enabling the execution of database queries and dynamic content generation alongside regular HTML elements. This approach streamlined web development by allowing developers to create mostly static websites and add dynamic elements where necessary.

The Rise of Structured Programming

PHP’s initial success lay in its simplicity and ease of use. It catered well to tasks like creating contact forms or displaying database query results within web pages. As this approach gained popularity, PHP gradually expanded its capabilities, eventually matching full-fledged programming languages. However, challenges arose when developing larger applications, as PHP lacked a structured approach and clear separation of logic and display code.

The Two Sides of PHP

Today, the community is divided into two main camps: those who adhere to PHP’s original design and those who have transformed PHP into an Object-Oriented language. The latter group has introduced significant improvements and embraced modern development practices, including frameworks like Laravel, Zend, and Symfony. However, these advancements often come at the cost of PHP’s original simplicity.

The Structure Conundrum

A key challenge in traditional PHP development is the lack of application structure. Unlike well-structured approaches like the Model-View-Controller (MVC) pattern, PHP’s original design revolves around web pages as the central units of development. This approach can lead to unpredictable data flow and code repetition. For instance, database queries are often scattered throughout files responsible for generating user-visible content.

Evolution of PHP Transformation: Retaining Uniqueness or Conforming to Standards

As PHP has evolved, it has incorporated elements from other programming languages, moving away from its originality. Deprecated functions, like the mysql_ extension, are now replaced with more modern practices. In modern applications, the view focuses solely on HTML, while a model handles database interactions, and a controller manages data flow. While these changes improve PHP’s structure, they also dilute its distinctive features.

PHP in Content Management Systems (CMS)

One prominent area where PHP is extensively used is in Content Management Systems (CMS) like WordPress and Drupal. These systems strike a balance between old-school approaches and modern Web Applications. While they may not always exhibit elegant internal structures, they do not rely on deprecated functions like mysql_ extension. WordPress alone powers a significant portion of the web.

Conclusion: Evolution of PHP Enduring Legacy

PHP’s journey from a simple toolset for web development to a versatile scripting language has been marked by controversy, adaptation, and evolution. Its unique approach, ease of use, and rapid deployment capabilities have contributed to its longevity. While has shed some of its originality in favor of modern programming practices, it remains a powerful tool in the hands of developers who understand its strengths and weaknesses. Ultimately, Evolution of PHP future will be shaped by those who continue to push its boundaries and redefine its role in the ever-changing world of web development.

Exploring PHP Compilation to Web Assembly

Unlocking the Potential of PHP for Web Browsers

In the realm of web development, the possibilities are ever-evolving, and the advent of WebAssembly (Wasm) has opened new doors for programming languages traditionally used on servers. Among these languages, PHP, a stalwart of the web, may seem like an unlikely candidate for browser-based execution. However, with the aid of Oraoto’s compilation scripts, achieving a PHP WebAssembly build that mirrors the functionality of PHP on a server or in a command-line interface (CLI) is more achievable than one might imagine.

The Ease of Compiling PHP to WebAssembly

PHP is renowned for its versatility, serving as the backbone for countless websites and web applications. Transitioning it into the browser environment may sound complex, but Oraoto’s compilation scripts streamline the process. These scripts facilitate the creation of a PHP WebAssembly (Wasm) build that faithfully reproduces PHP’s behavior on a server or in a CLI.

While there are certain limitations to the current implementation, such as the ability to only evaluate code and receive printed PHP lines, the potential for crafting innovative solutions remains vast.

Constructing a Playground for Laravel Collections

Laravel’s collections have won the hearts of developers for their ability to simplify working with arrays of data. However, mastering the nuances of these collections can require some trial and error, often involving a back-and-forth between code and documentation. Creating a Laravel collection playground in the browser, reminiscent of JSFiddle, offers an excellent opportunity to explore PHP in a browser context while building something exciting.

For those eager to experiment, the repository on Github provides an interactive platform for hands-on exploration.

The Inner Workings of the Playground

The Laravel Collection Playground relies on a compact PHP package that receives input JSON data and collection code from Vue. This code is then compiled into a Phar (PHP executable) file alongside Laravel’s collection component. The process involves converting JSON data into a collection and using the eval function to execute the provided collection code. Any results or errors, including caught Exceptions or Throwables, are encoded into JSON format and presented to the user. In the JavaScript environment, the PHP’s stdout is connected to display the execution outcomes, offering a surprisingly seamless experience. Furthermore, thanks to Progressive Web App (PWA) support, this playground can even be used offline.

Exploring the Potential of Running Laravel Client-Side

Imagine a world where you can run an entire web application built in Laravel entirely on the client side—truly serverless. To embark on this journey, we looked at the TodoMVC project, a standard framework testing ground, as a suitable candidate.

The first challenge we faced was making requests to Laravel, considering that no web server was in operation. Traditional web requests were out of the question, prompting us to devise a creative solution. Our approach involves running the Laravel framework with a mocked PSR7 request, akin to how the framework operates during integration tests. To facilitate this, we encapsulated the framework’s request cycle within a function:

After a successful console test, Laravel and all its dependencies are bundled into a Phar file. This Phar file is then integrated into the WebAssembly binary. Notably, due to the utilization of SQLite, application state persistence between (simulated) requests is achieved. However, this state is reset upon each reload, as the storage is temporary.

Experimenting in the browser’s console, you can add new todo items and make requests to the index method, effectively simulating an interactive web application.

Concluding Thoughts on PHP in the Browser

While the concept of running PHP in the browser is undeniably intriguing and opens doors to novel possibilities, it comes with its own set of challenges and limitations. Here are some key takeaways:

Performance Considerations: PHP in the browser can be approximately five times slower than its traditional server-side counterpart.
Resource Intensiveness: It consumes over 1GB of memory during startup, which may pose performance issues on lower-end devices.
Browser Compatibility: The technology is primarily compatible with recent desktop versions of Chrome, Firefox, and Safari, limiting its accessibility.
Compilation Overheads: Compiling a WebAssembly build can be time-consuming, especially for code changes, as it’s required each time.
Limited Functionality: PHP in the browser is confined to the capabilities of JavaScript, meaning certain functionalities, such as web requests, are unavailable, restricting its potential.
Download Size: Users need to download the entire PHP build and associated code (unless cached client-side), resulting in a substantial file size of around 4MB.
Debugging Complexity: Debugging can be challenging, as the available debugging information is limited, offering little insight beyond PHP’s exit codes.

In conclusion, while PHP in the browser is a fascinating concept, it currently faces several practical hurdles that need to be addressed for widespread adoption. Nevertheless, its potential for innovation and exploration in the web development landscape remains undeniable. As technology continues to advance, we can anticipate further developments in this exciting field.

Exploring PHP 8’s JIT Compilation

PHP 8 introduced JIT compilation, a feature that has sparked extensive discussions in the PHP community. However, it’s essential to understand that PHP’s JIT compiler is more than just a performance enhancement. In this comprehensive guide, we will delve into the world of PHP JIT compilation, covering its history, functionality in PHP 8, its impact on PHP’s future, and its potential applications.

Origins of PHP JIT Compilation

Before we explore the PHP 8 JIT compiler, let’s take a step back and understand how PHP traditionally executed scripts. PHP scripts were parsed and compiled into “byte codes,” which are pseudo-instructions for a virtual machine known as the Zend Engine. This virtual machine’s role was to take these byte codes, compile them into machine code, and execute them.

In PHP 5.5, the introduction of OPcache improved performance by storing compiled byte codes and reusing them for subsequent requests, skipping the parsing and compilation steps. This caching mechanism significantly enhanced PHP’s speed. However, even with OPcache, certain bottlenecks persisted, especially in applications built on modern PHP frameworks.

PHP 7.4 introduced opcache preloading, allowing administrators to specify scripts for pre-compilation during startup, further reducing the startup overhead. Despite these optimizations, there were still limitations due to memory constraints.

The Long-Term Impact of JIT

PHP’s JIT compilation, introduced in PHP 8, builds upon the concept of bytecode caching. While OPcache removed the need for parsing and compilation into opcodes, PHP 8’s JIT adds an extra layer of caching by storing native machine code. This innovation promises exceptional performance gains.

Function-Based JIT

Initially, PHP developers had to mark specific code for JIT compilation. However, this approach proved ineffective in real-world applications, such as WordPress, as it introduced overhead that negated the performance benefits of PHP 7.4.

JIT Compilation in PHP 8

PHP 8’s JIT compilation takes a different approach, using “traces” to determine which code should be compiled. A trace includes VM instructions (opcodes), runtime information, operand types, context classes, and invoked functions. The JIT analyzes the frequency, length, and operations within a trace to decide if it warrants compilation.

Performance Impact of JIT Compilation

PHP 8’s JIT compilation offers substantial performance improvements for numerical calculations and modest gains for typical web applications. Let’s explore these improvements in different scenarios:

PHP Benchmark Suite

PHP 8 JIT: 3x Faster

WordPress

PHP 8 JIT: 3-5% Faster

Framework-based Apps

No Significant Difference

While JIT compilation accelerates PHP’s execution speed, its primary beneficiaries are applications typically not developed in PHP, such as those involving extensive data processing or graphics manipulation.

PHP JIT Compilation and Machine Learning

JIT compilation has the potential to reshape PHP’s role in machine learning and big data ecosystems. PHP’s user-friendly syntax and JIT’s prowess in CPU-intensive tasks make it a promising contender in these domains. Existing PHP machine learning libraries like Rubix ML and PHP-ML are poised to leverage JIT for enhanced performance, facilitating their integration into web services.

Final Thoughts

PHP 8’s JIT compiler, while not a universal performance panacea, opens new possibilities for PHP as a language. Its significance becomes particularly apparent in data-intensive fields like machine learning. As PHP continues to evolve, its role in the software development landscape may expand further.

For a deeper dive into PHP 8’s JIT compiler, don’t miss our accompanying webinar, where we delve into the details and explore additional benefits, such as code migration from C to PHP and improved static analysis tool performance.
