If you are a novice, eager to make a career in PHP, or do not have that much knowledge about it, in this article, we will talk about the difference between PHP7 and PHP5. PHP has brought forth an end number of versions of web development from 1994 to 2020 and has also been upgraded. Show PHP is a hypertext preprocessor and is a widely used open-source scripting language. PHP is perfect for web development can be embedded in HTML.

Well, PHP6 was a failure, and the new version was renamed PHP 7. One of the most interesting events in 2015 in the PHP world was the release of PHP 7, 10 years after the release of the last major version, PHP 5. PHP 7 unleashes plenty of new features and outperforms PHP 5.x by a wide margin. PHP7 promises enhanced performance, low demand on servers, upgraded cost-effectiveness, and environment-friendly operation as it consumes less power. PHP7 advances from PHP5 in speed and connectivity. So, it is important to accept this upgrade as the growing web surfers demand fast connectivity. PHP7 is the next-generation web version straight after PHP5 skipping PHP6. Let us now dive deep into the differences between php5 and PHP 7.
What is PHP 5?PHP 5 was released to bring a brand new functionality to the PHP language. The PHP team’s primary focus was on what was missing or not well supported in the older versions. The PHP5 was focused on 3 major areas: Object-Oriented programming, XML, and MySQL support. PHP5 presents a completely reworked object model, which now offers:
Now, objects are both assigned and passed by reference rather than by value. So, the necessity to liberally sprinkle ampersands throughout your code is not required. Features of PHP 5
What is PHP 7?The creation of PHP 7 was spearheaded by Dmitry Stogov, Nikita Popov, and Xinchen Hui. These three developers designed an experimental branch of PHP, which they originally called PHP Next Generation, often abbreviated as PHPNG. The PHP community accepted this new scripting language since it offered notable changes in performance, and continued to develop it into the stable version of the language now known as PHP 7. Released in December 2015, PHP 7 guarantees fast performance for websites and online applications. It is estimated that PHP 7 offers a 100 percent improvement in terms of performance, speed when compared with PHP 5.6. This major speed improvement enables web developers to design sites that render exciting and appealing interactive features that still respond to user input as quickly as web users expect it to work. Another reason to create PHP 7 is the need to develop scripting languages that run more efficiently in terms of speed and performance. This urge is driven by two factors: the necessity to lessen costs and the need to reduce power consumption to protect the environment. Compared to PHP 5.6, PHP 7 places considerably reduced demands on servers, making it a more cost-effective and environment-friendly choice. Very little energy is required to power servers running PHP 7 applications. PHP 7 introduced new syntax features that are amazingly effective for developers to know and use daily like the “syntactical sugar”. This syntactical will make development in PHP 7 quite easier. When updating to PHP 7, it is best to ensure that your code includes tests, like unit and integration tests. These tests should catch any concerns with your application before they show up as bugs in a live environment. Features of PHP 7Below are few features of PHP version 7 –
This example demonstrates a function “foo” that returns an array. In PHP 5.6, developers would not specify the return type. Explicitly stating return types makes the code much easier to read. It becomes useful when debugging your code or working with code that was written by someone else.
Key DifferencesPHP7 is way more advanced than PHP5 in speed and connectivity and so, it is necessary to take the upgrade into consideration as the growing web surfers expect fast connectivity. PHP 7 is an improved version of PHP 5 that provides faster performance while using less storage. PHP5 coding is much simpler than traditional coding, and PHP 7 provides developers with a simple coding system. The upgraded PHP7 engine is regarded as a next-generation design. With PHP5, handling errors for the development process is quite tedious for the developers. With PHP7, handling fatal errors is seamless. Simultaneous running of several activities is difficult with the PHP5 version which is overcome in the PHP7 script. Differences Between PHP5 and 7PHP 5 Vs PHP 7
Since January 1, 2019, PHP 5 is no longer supported with security fixes, starting on 1 January. This means that even if a vulnerability is discovered, it won’t be resolved, leaving your website at risk. PHP 7 has many improvements over PHP version 5. The announcement of PHP 7 discarded old and out-of-date code and paved the way for new features and performance upgrades in the future. Thus, PHP7 has proven itself better than PHP5 in terms of speed, handling of errors, etc. ConclusionAdditionally, PHP is supposed to gain additional performance optimizations soon. Despite having some compatibility breaks with past releases, most of the issues are simple to fix. Libraries and frameworks are now relocating their code to PHP 7 thus making available the latest versions. We encourage you to give it a try and see the outcomes for yourself. Maybe your application is already compatible and waiting to use and benefit from PHP 7. Ideally, you should upgrade to PHP 7.4, which is the latest version of PHP. This version will be fully supported for another year and will receive security updates for a year after that. PHP 7.2 went end of life (EOL) on the 30th November 2020. This implies that security flaws will no longer be resolved and sites are exposed to significant security vulnerabilities. Frequently Asked QuestionsWhy PHP 7 is faster?
