Best practices in PHP for 2018




The relevant and popularity of PHP as a server-side programming language will remain intact in 2018. According to the latest usage statistics posted on several websites, the latest version of PHP is currently being used by less that 10% of all websites. Most web developers will switch to PHP 7.x in 2018 to build web applications that run faster and consume less memory. Likewise, the developers will execute PHP code through various micro and full-stack web frameworks to build custom web applications quickly and efficiently according to varied business requirements. At the same time, the developers will implement a number of PHP coding best practices to keep the code base clean and the web application maintainable.
7 PHP Development Best Practices Web Developers Must Implement in 2018
1) Choose Coding Style according to PHP Framework or Libraries
Web programmers can format and share PHP code more efficiently by using various coding styles – PSR-1, PSR-2, PSR-3 and PSR-4. He can use the coding styles interchangeably. But the latest version of the coding style may not support some of the coding standard included in the latest version. Also, the coding style followed by individual PHP frameworks and libraries differ. Some of the PHP web frameworks and libraries even do not follow the latest coding style. Hence, the developers need to use the coding style followed by the web framework and libraries used by the specific project.
2) Manage Project Dependencies with Composer
It is also important for web developers to choose the right PHP libraries and manage them efficiently. The developers can easily manage various PHP libraries and their dependencies by using a robust dependency manager like Composer. Composer is designed as an application-level package manager for PHP. It even simplifies dependency installation and management by providing standard methods. They even have option to run Composer through a command-line interface, and manage dependencies by running specific commands.
3) Use PHP Debug Bar to Debug Code Efficienty
In addition to writing clean and maintainable code, the PHP programmers also need to find and repair all errors in the code. They must explore ways to debug the PHP code efficiently to locate and repair all errors in the code. The PHP developers have option to choose from a wide range of debugging tools. But they must consider using PHP Debug Bar to identify the coding errors quickly based on the profiling information displayed at the bottom of the page. They can even install PHP Debug Bar without putting extra time and effort. Also, PHP Debug Bar can be integrated seamlessly with various projects.
4) Explore Ways to Use Service-Oriented Architecture
Service-oriented architecture (SOA) helps developers to build websites with services or functions which can be invoked by clients regardless of the device, operating system, or programming language. Despite being platform-independent, the services or functions make web applications deliver richer user experience by facilitating data translation and improving information flow. There are a number of PHP web frameworks – Laravel, Yii, Zend and Symfony – that enables web application developers to use SOA. The PHP developer must use one of the HTTP-centric web frameworks to build web applications with components that run independently while interacting with each other seamlessly.
5) Optimize Database Operations
While writing PHP code, programmers often ignore the significance of optimizing database operations. They must optimize database operations while writing code to improve the PHP application’s speed and performance. The PHP programmers can easily make the web application consume less memory by closing database connections in the code. Likewise, they must explore ways to make the application run faster by not hitting the database frequently. They can write comprehensive SQL queries to perform common database operations without hitting the database frequently. At the same time, it is also important to identify and update the slow SQL queries to make the web application access resources quickly and smoothly.
6) Opt for JSON Data Format instead of XML
While writing web applications in PHP, a programmer has option to choose from two used format for data exchange – JSON and XML. But he must remember that XML uses more words than JSON. Also, JSON parses data much faster than XML. The developer can even accelerate parsing by availing the built-in functions provided by PHP – json_endcode and json-decode. They can use json-encode function to return the JSON representation of a value and json-decode to decode a JSON string into a PHP variable. If a PHP programmer prefers XML to JSON, he must use regular expressions instead of DOM manipulation for data parsing.
7) Adopt Test Driven Development through PHPUnit
Unlike conventional software development practices, test driven development (TDD) allows developers to write code only after an automated test fails. Hence, it becomes easier for developers to deliver high quality web applications by writing readable code and avoiding code duplication. PHP does not provide any built-in feature to facilitate TDD. But the PHP programmers can easily implement TDD by using a robust programming-oriented unit testing framework like PHPUnit. The features provided by PHPUnit will make it easier for programmers to define and run tests before writing code.
In addition to implementing these development best practices, it is also important for developers to pick the right PHP web framework. The full-stack web frameworks for PHP makes it easier for programmers to build large and complex web applications by providing several advanced features and tools. But the additional features provided by the web framework often impact the web application’s performance and speed. Hence, the PHP programmers must spend some time in evaluating the pros and cons of individual web frameworks based on precise needs of each project to build PHP applications that run faster and deliver richer user experience.
