mac brew reinstall php

Over time, developers need to constantly update and upgrade their tools and skills to adapt to changing technical environments and needs. macOS is a popular operating system loved by developers for its ease of use and performance. When running web projects on macOS, it is necessary to install and manage different versions of PHP. Brew is a popular package manager for installing and managing different versions of software packages on macOS. In this article, we will learn how to reinstall PHP using Brew.

First, we need to install Brew. You can install it according to Brew official documentation. Then we need to add the Brew PHP repository. This can be done by running the following command:

brew tap homebrew/homebrew-php

After running this command, Brew will automatically add the Homebrew PHP repository for you. Note that this repository also provides many other PHP-related packages, such as PHP extensions, PHP libraries, and PHP tools.

Next, we need to check the currently installed PHP version. You can get the current PHP version by running the following command:

php -v

After knowing the current PHP version, we can uninstall the version by running the following command:

brew uninstall php{版本号}

Here, put {version number }Replace with the actual version number to uninstall. For example, if you want to uninstall PHP 7.3, you should run the following command:

brew uninstall php@7.3

Once the uninstallation is complete, you can run the following command to install the new PHP version:

brew install php{版本号}

Similarly, replace {version number} Replace with the actual version number to install. For example, if you want to install PHP 7.4, you should run the following command:

brew install php@7.4

Once the installation is complete, you can confirm whether the new version of PHP has been successfully installed by running the following command:

php -v

Additionally, If you need to install an extension for a new version of PHP, you can use the following command:

brew install php{版本号}-{扩展名}

For example, if you want to install the curl extension for PHP 7.4, you can run the following command:

brew install php@7.4-curl

Reinstall by using Brew PHP, we can easily install and manage different versions of PHP and PHP extensions. This is useful for developers who need to manage several different web projects simultaneously. At the same time, Brew also provides many other powerful software packages that can help developers increase productivity and streamline workflow. Therefore, it is recommended to learn and use Brew to manage software packages and tools on macOS.
