Fastest Internet with PHP 7
A general rule when creating a web page is to ensure short loading times. Optimizing the loading speed of a website will always result in a lower bounce rate and, therefore, in an increase in the time your visitors spend browsing it. In addition, ensuring quick access to a web page will not only have a positive effect on the browsing behavior of users, but will also be rewarded with a better search engine positioning such as Google. Among the options to improve the loading speed of a website is the optimization of the programming language used. Those developers of dynamic web pages that use PHP as a script, will notice great improvements in performance with the new PHP7, which can still be higher with the latest versions 7.1 and 7.2 already published.
Using antiquated versions of PHP, of which PHP 7.0 also forms part since December 2018, represents a potential security risk. The community around PHP only supports current versions such as PHP 7.1, PHP 7.2 or the future PHP 7.3.
The fact that shortly after the security support for PHP 7.0 ceases also disappears the official support for the popular PHP 5.6 in December 2018 demonstrates the progress of the new version of the scripting language. Two years after its first launch, it can be said that today PHP 7.0 has definitely conquered the network.
What is PHP?
PHP is a very popular programming language used especially for the creation of dynamic web pages. It is open source and distributed under the PHP license, which makes it possible to reuse or modify the source code without additional costs. The basic function of PHP is to read form data and convert it into PHP variables. Subsequently, the variables can, for example, be entered into a database or sent by e-mail. The advantages of PHP include its integration with the Internet protocol and broad support of different database models . This programming language is used by more than 82 percent of the web pages of the market and is usually, therefore, pre-installed in most web hosting providers.
What’s new in PHP7?
Because the development of PHP6 was suspended, the new PHP appears as the successor of PHP 5 and becomes the sixth great version of PHP. In itself, the programming language does not change much, which makes PHP 7 still compatible with previous versions . In the same way, most applications developed for PHP 5.6 do it. The only compatibility problem appears with very old extensions that have not been adapted. The best example in this case is the extension to access MySQL databases, which ultimately is not compatible with version 7, so it is advisable to use the latest MySQLi version or the PDO (PHP Data Objects) plugin.
The main novelty of PHP7 is the remarkable increase in performance achieved by the team of developers, thanks to several optimizations of the PHP kernel . In addition to the increase in speed (PHP7 is twice as fast as its predecessor), the new PHP takes up less memory. In addition to having completed the commands (Bytecode), a large part of the core has been completely reformed – including significant changes in components such as parsers, Lexer and Bytecode Generator. Thus, PHP 7 creates an abstract syntax tree that serves as the basis for the creation of byte code commands, instead of creating the code directly from the analyzer. This greatly simplifies making changes to the PHP syntax.
Another feature of the new PHP is the possibility of defining scalar data in the programming code. that is, those that store only one value, such as return types. In this way, PHP is extended with Integer, Boolean, Float and String types.
In summary, the most important novelties are:
- Performance improvements, almost double the version 5.6
- Low RAM requirements
- Implementation of an abstract syntactic tree for the generation of codes
- Constant support of 64-bit systems
- Improved error handling, errors rarely lead to system crashes
- Generator of cryptographically more secure random numbers
- Removing old and outdated server extensions and interfaces
- Definition of scalar data types and code return types
PHP7 improves the performance of WordPress and other CMS
The integration of the PHPNG (PHP Next Generation) version in the main PHP version is responsible for improving performance. PHP 7 is also characterized by an improved core that includes the new Zend Engine 3.0. During the first reference tests, before the launch of the new PHP, it became clear that the new version created by Zend Technologies offered great benefits for online store creation and management systems, content management systems (CMS) and frameworks.
1 & 1 IONOS is the only hosting provider that ensures that all older versions of PHP can continue to function without security problems even when the community support ceases. Thanks to PHP Extended Support the client has the freedom to choose if he wants to change and when he wants to change it.
The Magento e-commerce software can be executed at twice the speed of PHP 5.6, which reduces memory usage by 30 percent. In addition, the new PHP can manage up to three times more visitors than its previous version. When compared to content management systems like Drupal or WordPress, something similar happens: Drupal 8 runs almost 72 percent faster, and WordPress tests have shown that they only require a quarter of the CPU for its operation. Both CMS show an increase of 50 percent in terms of possible visits. PHP 7 allows the Laravel and Zend frameworks, as well as the SugarCRM content manager, to receive almost twice as many visits per second. Compared to its previous version, PHP 7 is able to cope with high traffic rates, guaranteeing a high speed of access and load. In this way, although the volume of visits increases, it is not necessary to reinforce the hardware. The new PHP meets the requirements required for the operation of WordPress, Magento or similar projects without generating additional costs.
