If the default PHP is not configured on your server, you'll need to set it up. Here's how you can do it:

1. Determine Available PHP Versions:

   First, check which PHP versions are available on your server. You can do this by running:

   bash

• php -v

  This will list the installed PHP versions.

• Choose a Default PHP Version:

  Decide which PHP version you want to set as the default. You can choose from the available versions listed in step 1.

• Set Default PHP Version:

  The method for setting the default PHP version can vary depending on your server's configuration. Here are two common methods:

  Method 1: Using a Command Line Tool (such as update-alternatives):

  On some Linux distributions, you can use the update-alternatives command to set the default PHP version. For example:

  bash
• sudo update-alternatives --set php /usr/bin/php7.4

  Replace /usr/bin/php7.4 with the actual path to the PHP binary of the version you want to set as default.

  Method 2: Through Web Server Configuration (Apache or Nginx):

  If you're using a web server like Apache or Nginx, you can configure it to use a specific PHP version. For Apache, you'll need to adjust the LoadModule directive to load the correct PHP module. For Nginx, you'll need to configure the fastcgi_pass directive.

• Restart Web Server:

  After setting the default PHP version, you'll need to restart your web server for the changes to take effect. Use one of the following commands based on your web server:

  For Apache:

  bash

For Nginx (if using PHP-FPM):

• sudo systemctl restart php-fpm sudo systemctl restart nginx

• Verify Default PHP Version:

  To ensure that the default PHP version has been set correctly, run:

  bash
• php -v

  This should display the version you've set as default.

• Configure PHP Settings:

  Now that you have a default PHP version, you can further configure it by editing the php.ini file. This file contains various settings that control how PHP behaves.

  bash
