Differences between php 5.2 and 5.6 code#
At this very moment, the compilation or recompilation of the code is made on the go which results in speed improvement. JIT system continuously examines the code that is being executed and looks for parts that could be sped up. This principle is also known as dynamic translation. But what makes it unique is a Just in Time engine, that allows compilation of the code during the execution of the program. One way or another, each programming language is translated to the binary code by using the compiler. The machine native language is still binary code. The programming language is just an easier way to talk to the machine. You may already know that PHP, C++, Swift, and any other modern programming language is not communicating directly to the hardware. It is based on JIT compiler that serves as an execution engine for the PHP. HHVM was highly popular before the release of PHP 7. Shortly speaking it compiles PHP into native machine code by using just-in-time technology (JIT). HHVM is an open-source virtual machine developed by a Facebook team. Here’s another benchmark made with the help of OpenLiteSpeed:Īs you can see, there is also addition bar called HHVM (HipHop Virtual Machine). You can also watch this test made by Marcos Nobre on Youtube: We’ll also test performance with and without Super Cache Plugin for WordPress. In our tests, we performed benchmarking by using the Apache benchmark tool.
We’ll take two websites that have been set up the same and running on the same amount of memory (512-megabyte digital ocean droplet server) and on the same LAMP tech stack. The easiest way of doing benchmark is testing between two WordPress-based websites ( which is not the fastest solution) that run on PHP 5.6 and PHP 7.0. The answer to this question lies in the number of advancement and core revisions that were made to the PTP 5 version. Roughly two times better than the old one to be precise. How does that happen that a new version is so much better than the old one you may ask.
Read more was PHP 7.4.9 Released and PHP 8.0.0 Beta 1 available for testing Advantages of PHP 7 over PHP 5.6 PHP 7 provides roughly 1.8x increase in performance comparison to PHP 5.6.Over 70% of developers are using PHP 7 in their development environment, which means you can save some time for your programmers because they won’t need to switch back to PHP 5.6 during the production stage.Only 3.8% of developers declined and said they would use PHP 7 only if their hosting company will force them to use it.69.6% of developers said they are ready to use PHP 7 in production according to Nestify survey.Then, let me give you several facts that will assure you that choosing PHP 7 is a good idea. I see you don’t want to take my words for granted. In fact, if you’re not dealing with legacy code, you should just kick-start your project on PHP 7 and stick to it. So, if you just wondering around and want to make sure that PHP 7 is right for you – the answer is YES. And, well… if you’re going into development and making final research before signing a contract, this question might bother you. The advanced version that is meant to replace PHP 5 and PHP 6 (failed one) version. It has been awhile over a year since PHP 7 was released.
