How to get the current version number in ThinkPHP (two methods)

ThinkPHP is a PHP framework mainly used for rapid development of high-performance web applications. ThinkPHP versions are upgraded very frequently, and different versions will bring various new features and optimizations. When using ThinkPHP for development, we need to know the current ThinkPHP version number in order to better select the corresponding development documents, plug-ins, extensions and other resources.

This article will introduce how to get the current version number in ThinkPHP. In ThinkPHP, there are two main ways to obtain the version number: obtaining through variables and obtaining through constants.

Get the version number through variables

In ThinkPHP, we can get the currently used version number through the $version variable. This variable is defined in the ThinkPHP entry file index.php, and its specific code is as follows:

// 定义ThinkPHP版本号
$version = '6.0.0';
// 框架路径
define('THINK_PATH', __DIR__ . '/thinkphp/');
// 加载框架的引导文件
require THINK_PATH . 'start.php';

We can get the currently used version number through the following code:

echo $version;

Get the version through constants No.

In addition to obtaining the version number through the $version variable, we can also obtain the version number through constants. In ThinkPHP, the version number of each version is defined as an independent constant, and we can obtain the version number of the corresponding version through this constant.

The following are the version number constants defined in ThinkPHP6.0 version:

// 定义ThinkPHP版本号
define('THINK_VERSION', '6.0.0');

We can get the currently used version number through the following code:

echo THINK_VERSION;

Summary

Through the above two methods, we can easily obtain the currently used ThinkPHP version number. This method can help us better select the corresponding version of development documents, plug-ins, extensions and other resources, thereby speeding up our development efficiency. It is worth noting that using different versions of ThinkPHP may bring different user experience and optimization effects, so when choosing a version, you should choose it based on actual needs.
