How to Install Pear Package

To install a PHP PEAR package, begin by ensuring the PEAR installer is available on your system. Open a command prompt or terminal and enter the command "pear install [package-name]." Replace "[package-name]" with the specific name of the PEAR package you want to install. The installer will automatically fetch and install the package along with its dependencies. Once the process is complete, you can incorporate the newly installed PHP PEAR package into your projects, enhancing functionality and streamlining development.
