Which version of php is stable?

PHP language is one of the most commonly used open source scripting languages ​​at present. Many websites will choose this language to build. Since there are many versions of PHP language, there is a question, which version is better to choose? Which version of PHP is stable? The following article will introduce it to you and hope it will be helpful to you.

Usually, the newer the PHP version, the better. For example, PHP5.6 and 7.0 versions will be much faster than the following 5.3/5.2, but some programs are not suitable for newer versions. The version of PHP is not supported, so you can only choose the program with the best stability and compatibility according to the website program.

Currently, the highest version of PHP is 7.2.x.x. However, we generally use php5.5.x or Php5.6.x, and even quite a few use PHP5.3.X and PHP5. 4.X version. It is generally recommended to choose version 5.6. This version is more stable and is also used by most enterprises.

The main reason is that many programs do not support new PHP versions, especially some programs that have not been updated for a long time. They only support PHP5.2.X series versions. Which version to choose depends on what you are using. programs and corresponding templates, rather than blindly pursuing exorbitant versions. If you want to be compatible with more programs, it is recommended to use PHP5.5.X version. If you want to pursue higher performance, PHP5.6.X or even PHP7.0 series are recommended.

The current wordpress program supports PHP7.0 very perfectly. However, some templates that have not been updated have many problems under 7.0. Therefore, it is recommended that partners who use the wordpress program pay special attention when choosing the PHP7.0 version. Pay attention to whether the template and plug-ins you use are compatible. If it is a commercial template, it is recommended to consult the author and do not blindly upgrade and replace it.

In the current bt system, the PHP version can be downloaded and combined by itself. Due to factors such as templates, PHP5.6 and PHP7.0 are used. Therefore, I would like to remind you not to blindly pursue a version that is too high, and configure and choose according to the best PHP environment for your program. The newer the version, there will be more bugs at the beginning, and the stability may also be compromised. The old version has been tested for a long time after all.
