PHP, the popular server-side scripting language, has been a cornerstone of web development for over two decades. With each new version, the language has evolved to meet the changing demands of modern web applications. In December 2018, PHP 7.3 was released, bringing with IT a host of new features and improvements that promise to revolutionize web development as we know it. In this article, we’ll explore the groundbreaking update that is PHP 7.3, and find out what developers have been missing out on.
What’s New in PHP 7.3?
PHP 7.3 introduced several new features and improvements that enhance the performance, security, and overall developer experience. Let’s take a closer look at some of the key changes in this groundbreaking update:
Flexible Heredoc and Nowdoc Syntax
PHP 7.3 introduced flexible heredoc and nowdoc syntax, allowing for easier handling of multiline strings. This improvement makes it simpler and more intuitive to work with large blocks of text within PHP code, eliminating the need for complex concatenation or escaping characters.
Awaited in Async Functions
With the growing demand for asynchronous programming in web applications, PHP 7.3 added support for the awaited keyword within async functions. This feature enables developers to write asynchronous code more elegantly and efficiently, improving the performance and responsiveness of their applications.
Improved JSON Encoding
JSON has become the de facto standard for data interchange in modern web applications. PHP 7.3 enhanced the json_encode() function to provide better error handling and support for JSON_UNESCAPED_SLASHES and JSON_INVALID_UTF8_IGNORE options, making it easier to work with JSON data in PHP.
Is Countable Interface
PHP 7.3 introduced a new Countable interface, allowing objects to be used with the count() function. This improvement enables developers to work with custom data structures and classes more efficiently, providing greater flexibility and consistency in their code.
Performance Improvements
Performance is always a key consideration in web development, and PHP 7.3 delivered significant improvements in this area. The update introduced optimizations to the PHP engine, resulting in faster execution of code and reduced memory consumption, leading to better overall performance for web applications.
What You’ve Been Missing Out On
Prior to PHP 7.3, developers were limited in their ability to work with asynchronous code, handle large blocks of text, and optimize the performance of their applications. With the introduction of flexible heredoc and nowdoc syntax, awaited in async functions, improved JSON encoding, the Countable interface, and performance enhancements, PHP 7.3 has addressed these limitations and opened up new possibilities for web development.
By leveraging the new features and improvements in PHP 7.3, developers can write more efficient, readable, and maintainable code, leading to better overall productivity and performance in their web applications. This groundbreaking update has brought PHP to the forefront of modern web development, and developers who embrace these changes stand to benefit greatly from the enhanced capabilities of the language.
Conclusion
PHP 7.3 is a groundbreaking update that has revolutionized web development by introducing a host of new features and improvements. From flexible heredoc and nowdoc syntax to awaited in async functions, improved JSON encoding, the Countable interface, and performance enhancements, PHP 7.3 has addressed key limitations and opened up new possibilities for developers.
With the ability to work with asynchronous code more elegantly, handle large blocks of text more intuitively, and optimize the performance of their applications, developers can leverage the power of PHP 7.3 to write more efficient, readable, and maintainable code. The language has truly come of age, and those who embrace these changes will be well-positioned to thrive in the ever-evolving landscape of web development.
