In the world of web development, ThinkPHP has become a very popular development framework. As an open source framework, it occupies a very important position in the Chinese developer circle. As time goes by, ThinkPHP is constantly evolving and upgrading, and new versions of ThinkPHP are constantly being released. In this article, we will explain how to upgrade ThinkPHP.
Step one: Back up the original application
Before upgrading, we need to back up the current application, so as to avoid data loss caused by upgrade errors. First we need to back up the ThinkPHP framework. For single applications and grouped applications, the backup purpose of this part is the same. We only need to back up our "ThinkPHP" folder to another path.
For a single application, we need to back up the following directory:
For grouped applications, we need to back up the following Directory:
When backing up these files, we can use manual copying or use a packaging tool for backup.
Step 2: Download the latest ThinkPHP version
After we successfully back up the application, we need to download the latest version of ThinkPHP. Normally, we can find the latest version download address on the ThinkPHP official website.
Step 3: Decompress and copy the new ThinkPHP framework
Decompress the latest version of ThinkPHP you downloaded, and rename the decompressed folder to "ThinkPHP". Copy this folder to our application, paste it into the location of the original ThinkPHP folder, and overwrite the original framework file.
Step 4: Update application configuration files
According to the configuration files we backed up in the first step, we need to update them to the latest version. If our application is a single application, then we need to update the following files:
If our application is a grouped application, then We need to update the following files:
When updating the configuration file, we need to ensure that all configurations are checked and they are modified correctly.
Step 5: Upgrade the database
If the upgrade process requires changes to the database structure or data type, we need to use an upgrade script or migration tool to upgrade. Without such a tool, we would need to complete the process of upgrading the database manually.
Step Six: Test and Deploy
After the upgrade is completed, we need to test the application. If the website can be displayed normally, it means the upgrade is successful. If there are any problems, you need to confirm whether the problem is caused by the upgrade and fix it.
Finally, we need to deploy the upgraded program so that users can access it.
In this article, we explain how to upgrade ThinkPHP and introduce some necessary steps and processes. By following these steps, we can complete the upgrade of the application more easily and quickly.
