Php7 was launched in december2015, and some websites are still running in the old version one year after the initial launch. PHP 7 is a major change for improvement. This is one of the most commonly used scripting languages, and it is also a further improved version of the core foundation of WordPress. This article will discuss why it is important to upgrade to hosting that provides the right support, and why it helps your site. Advantages of PHP 7 for WordPress PHP 7 is currently in version 7.1.4, but key requirements still exist. This is the most important aspect of changing to 7 in PHP 5.6 and earlier versions. The
The new Zend engine is now called PHP next generation (NG). Significant reduction in memory usage abstract syntax tree consistent 64 bit support a large number of fatal errors are now turned into exceptions. Better and more secure number generators are compatible with the anonymous class OpenSSL 1.0.2e or later. So, don’t you know what all this actually means? I will explain all this in detail. Wait -6 what happened?!?! PHP6’s development cycle already exists, but the former’s attempt has not been made public (don’t worry, I didn’t miss it anyway). To prevent confusion, we decided to skip 6. This is to further improve the development of PHP 7 and introduce a more concise version with more functions and advantages. The
For those who don’t know the new Zend engine, Zend is not new, because PHP has existed since 1999. Zend is an execution engine that performs the actual analysis of the PHP language. C, and some upgrades have been made over time. PHP 5 The version used by X is called Zend engine II, which adds an extensible object model and performance improvement compared with the previous version. However, the new Zend engine (currently called next generation) of PHP 7 is the core of the actual speed improvement of PHP 7. Every time you hear statements that double the speed of PHP 7 and significantly reduce memory consumption, you will find that this is actually an improvement of Zend next generation. The
Next generation does this by changing the behavior of pointer operations (for example, the former Zend engine II) to structures. This change reduces memory consumption, garbage collection, and overall performance. More detailed instructions are provided on the PHP wiki. Only coding warriors are recommended. PHP 7 is faster. The change of the new generation Zend engine is the main reason for the speed increase. By reducing memory consumption, the time required for the scripting language to process information is also reduced. As a result, the number of servers required for PHP 7 to provide the same content is reduced This is really good for people who don’t want to speed up WordPress. The
This is a chart directly imported from PHP PDF: the number of requests per second basically tells the server and software how many users can view the site within a given time, so it is a good way to measure performance. The more requests the server can handle, the faster the web site. PHP 7 can replicate the performance of PHP 5.6 and directly compete with HVM, another scripting language interpreter created by Facebook. Why faster? Processing each request requires less CPU time, so you can double the number of requests processed in a given time. The
One of the most critical issues with improved error handling and 64 bit support for PHP is error handling. Before php7, because fatal errors do not call the error processor and interrupt the script, they can hardly be handled correctly, so you can ask questions. Improved PHP
Error handling uses throw able exceptions, so you can use a better handling mechanism to handle errors that developers could not use before. By creating exceptions, developers can get better information about actual errors and handle them appropriately. The
Male tip: now coding is much easier and less troublesome. Conversely, consistent 64 bit support means that PHP 7 now allows 64 bit integers and supports them on other platforms, such as Microsoft Windows, which runs on 64 bit by default. PHP 7 supports anonymous classes. All major object-oriented languages have the Convention of using anonymous classes. There are many such things in Java and c\. Anonymous classes are very useful and can speed up code execution if properly coded. Php7 must add anonymous classes to catch up with all major object-oriented languages. The
The unused PHP function php7 has the main house Kipping, which contains functions that are no longer used. For unknown people, functions that are no longer used are part of the code, because the code is too old or considered unavailable, so it is required to interrupt the use. Functions that are no longer used in PHP no longer work. PHP 7 developers have carefully considered many features that are no longer used. It is important to know that functions that are no longer used can corrupt code and potentially corrupt code. When you hear about the compatibility problem when WordPress is upgraded to PHP 7, this is where the website may be interrupted. The
The function that php7 no longer uses is the primary issue to be considered when upgrading the website to provide php7 hosting. If you run on PHP 7, old plug-ins and topics that call functions that are no longer used can stop running and will stop running. Therefore, all plug-ins and themes must be upgraded before switching to hosting that supports PHP 7. Male delete all codes that are no longer used. Now it is PHP5. PHP 7 runs in a much cleaner environment than x, and its performance is partly responsible. The
All this means that php7 runs faster, lighter, and with less memory usage, PHP5. Execute twice as much code as X in a given time to handle errors in a more concise way. All this leads to faster websites, better coding, and a better user experience. If you are interested in the performance of the site, the first order of the day is to upgrade all plug-ins and themes, and switch to hosting for PHP 7. And you’re lucky. The most popular hosting companies offer PHP 7 (or upgrade) for all programs. Here are some PHP 7 compatible hosting companies we recommend:
BlueHost optimizes WordPress hosting WP engine management WordPress hosting (wpexplorer also hosts) media staff management WordPress hosting plus others! If you like the current host, please consult the upgrade. Of course, there are other factors that contribute more to performance, such as using nginx and supporting a hosted service for web server caching, but we will discuss all these topics in a later article.
