PHP is a popular general-purpose scripting language that is especially suited to web development. Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world. A definition by php.net - PHP, which stands for "PHP: Hypertext Preprocessor" is a widely-used Open Source general-purpose scripting language that is especially suited for web development and can be embedded into HTML. Its syntax draws upon C, Java, and Perl, and is easy to learn. The main goal of the language is to allow web developers to write dynamically generated web pages quickly, but you can do much more with PHP. Programming languages evolve over time, but not by themselves. People who either designed the language or who have worked with it come up with ideas for improvement. Sometimes, those ideas come from ideas that have emerged in other programming languages. PHP has come a long way since its birth in the mid-1990's. From humble beginnings to becoming one of the most prominent and famous languages powering the web applications, the evolution of PHP is a geek's fairy tale. Very explosive growth from PHP 3 to now PHP 7 and going on. So advanced users or professional programmers require to upgrade them self time to time. The best things in using PHP are that it is extremely simple for a newcomer, but offers many advanced features for a professional programmer. Don't be afraid of reading the long list of PHP 7 features over PHP 5. You can jump in, in a short time, and start writing simple scripts in PHP 7. As PHP grew, it began to be recognized as a world-wide popular development platform. One of the most interesting ways of seeing this trend was by observing the books about PHP that came out throughout the years. Clearly, the large number of books, written by different authors, published by many publishers, and their availability in so many languages - are a strong testimony for PHP's world-wide success

If you're using PHP 4, then chances are good that an upgrade to PHP 5 is in your future. The more you've heard about the exciting new features in PHP 5, the sooner that upgrade is probably going to be. Although an in-depth, soup-to-nuts reference guide to the language is good to have on hand, it's not the book an experienced PHP programmer needs to get started with the latest release. What you need is a lean and focused guide that answers your most pressing questions: what's new with the technology, what's different, and how do I make the best use of it? In other words, you need a copy of Upgrading to PHP 5.This book is targeted toward PHP developers who are already familiar with PHP 4.

You'll find a concise appraisal of the differences between PHP 4 and PHP 5, a detailed look at what's new in this latest version, and you'll see how PHP 5 improves on PHP 4 code. See PHP 4 and PHP 5 code side-by-side, to learn how the new features make it easier to solve common PHP problems. Each new feature is shown in code, helping you understand why it's there, when to use it, and how it's better than PHP 4. Short, sample programs are included throughout the book.Topics covered in Upgrading to PHP 5 include: The new set of robust object-oriented programming features An improved MySQL extension, supporting MySQL 4.1, prepared statements, and bound parameters Completely rewritten support for XML: DOM, XSLT, SAX, and SimpleXML Easy web services with SOAP SQLite, an embedded database library bundled with PHP 5 Cleaner error handling with exceptions Other new language features, such as iterators, streams, and more. Upgrading to PHP 5 won't make you wade through information you've covered before. Written by Adam Trachtenberg, coauthor of the popular PHP Cookbook, this book will take you straight into the heart of all that's new in PHP 5. By the time you've finished, you'll know PHP 5 in practice as well as in theory.

Zend Framework 1 was one of the first major frameworks for PHP 5 and, for many, introduced object-oriented programming principles for writing PHP applications. Many developers looking to embrace a well-architected and supported framework chose to use it as the foundation for their applications. However, the first version was not without its faults. Zend Framework 2 is a significant improvement over its predecessor. It re-designed key components, promotes the re-use of code through modules, and takes advantage of features introduced in PHP 5.3 such as namespaces. The first release of ZF1 was in 2006. If you're maintaining an application built on it, this practical guide will help you to plan how to migrate to ZF2. This book addresses common issues that you'll encounter and provides advice on how best to update your application to take advantage of ZF2's features. It also compares how key components-including Views, Database Access, Forms, Validation, and Controllers-have been updated and how to address these changes in your application code. Written by PHP professional and Zend Framework contributor, coach, and consultant Bart McLeod, this book leverages his expertise to ease your application's transition to Zend Framework 2.

Build interactive, database-driven websites with PHP 7, MySQL 8, and MariaDB. The focus of this book is on getting you up and running as quickly as possible with real-world applications. In the first two chapters, you will set up your development and testing environment, and then build your first PHP and MariaDB or MySQL database-driven website. You will then increase its sophistication, security, and functionality throughout the course of the book. The PHP required is taught in context within each project so you can quickly learn how PHP integrates with MariaDB and MySQL to create powerful database-driven websites. Each project is fully illustrated, so you will see clearly what you are building as you create your own database-driven website. You will build a form for registering users, and then build an interface so that an administrator can view and administer the user database. You will create a message board for users and a method for emailing them. You will also learn the best practices for ensuring that your website databases are secure. Later chapters describe how to create a product catalog, and a simple e-commerce site. You will also discover how to migrate a database to a remote host. The final chapter will demonstrate the advantages of migrating to Oracle's MySQL 8. You will be shown step by step migration directions along with a demonstration of the tools available in SQL Workbench. Because you are building the interactive pages yourself, you will know exactly how MySQL, MariaDB, and PHP all work together, and you will be able to add database interactivity to your own websites with ease. What You Will Learn Build a secure database-driven website using PHP 7, MySQL 8, and MariaDB Create a product catalog Write a message board Move towards e-commerce Employ security and validation measures Migrate to Oracle's MySQL 8 Server platform Who This Book Is For Web developers with HTML, CSS and a limited Bootstrap experience.

Annotation A couple of years ago, Facebook switched its production servers from a PHP-to-C++ compiler to their own HipHop Virtual Machine (HHVM) and then launched a new version of PHP to run on HHVM called Hack. This comprehensive guide - written by a member of the core HHVM and Hack teams at Facebook - shows you how to get up and running with both HHVM and Hack.

Rural life in Southeast Asia is being transformed by new and intensifying processes of migration and mobility. Migration out of rural areas creates new forms of class mobility, familial relations, production processes and income. Migration into rural areas creates a new and sometimes marginalized workforce, contestation over resource access, and the juxtaposition of culturally different groups. At the same time, everyday mobility stretches the spatial boundaries of village and family life. The bounded space of the village is no longer adequate to understand the dynamics that are driving (and resulting from) rural social change. This collection of original studies explores the cultural, economic and environmental dimensions of intensifying migration and mobility in rural Southeast Asia at multiple scales. Diverse processes are explored including rural-urban flows, rural-rural movement, everyday mobilities, and international migrations into regional and global labour markets. Drawing on fieldwork in six countries across the region, these essays also explore what migration means for our understanding of class, citizenship, gender and the state in a rapidly changing part of the world. This book was based on two parts of a special issue of Critical Asian Studies.

The southernmost and poorest state of the Eurasian space, Tajikistan collapsed immediately upon the fall of the Soviet Union and plunged into a bloody five-year civil war (1992–1997) that left more than 50,000 people dead and more than half a million displaced. After the 1997 Peace Agreements, Tajikistan stood out for being the only post-Soviet country to recognize an Islamic party—the Islamic Renaissance Party of Tajikistan (IRPT)—as a key actor in the civil war as well as in postwar reconstruction and democratization. Tajikistan’s linguistic and cultural proximity to Iran notwithstanding, the balance of external powers over the country remains fairly typical of Central Asia, with Russia as the major security provider and China as its principal investor. Another specificity of Tajikistan is its massive labor migration flows toward Russia. Out of a population of eight million, about one million work abroad seasonally—one of the highest rates of departure in the world. Migration trends have impacted Tajikistan’s economy and rent mechanisms: half of the country’s GDP comes from migrant remittances, a higher share than anywhere else in the world. However, it is in the societal and cultural realms that migration has had the most transformative effect. Migrants’ cultural and societal identities are on the move, with a growing role given to Islam as a normative tool for regulating the cultural shock of migration. Islam, and especially a globalized fundamentalist pietist movement, regulates both physical and moral security in workplace and other settings, and brings migrants together to make their interactions meaningful and socio-politically relevant. It offers a new social prestige to those who work in an environment seen as threatening to their Islamic identity. The first section of this volume investigates the critical question of the nature of the Tajik political regime, its stability, legitimacy mechanisms, and patterns of centralization. In the volume’s second part, we move away from studying the state to delve into the societal fabric of Tajikistan, shaped by local rural specificities and social vulnerabilities in the health sector and gender relationships. The third section of the volume is devoted to identity narratives and changes. While the Tajik regime works hard to control the national narrative and the interpretation of the civil war, society is literally and figuratively on the move, as migration profoundly reshapes societal structures and cultural values.
