Introduction<\/h2>\n\n\n\n

This article explains how to send emails with a PHP application using PHPMailer<\/strong>. Before doing so, however, you must use Composer<\/strong> to download PHPMailer and automatically create an autoloader file.<\/p>\n\n\n\n

Note:<\/strong> Users often do not know how to proceed, hence this article.<\/p>\n\n\n\n

Note<\/strong>: The Glossary<\/a> contains explanations on multiple topics and can be consulted to clarify certain terms.<\/p>\n\n\n\n

Step 1: Installation of Composer<\/h2>\n\n\n\n

First of all, you need to connect to the N0C account via SSH (How to Create an SSH Key and Connect to an Account Remotely<\/a>). Then, you can proceed with the installation.<\/p>\n\n\n\n

Note:<\/strong> In the following commands, “user” must be replaced by the username of the N0C account in question.<\/p>\n\n\n\n

    \n
  1. Start by entering the following commands:<\/li>\n<\/ol>\n\n\n\n

    php -r \"readfile('https:\/\/getcomposer.org\/installer');\" > composer.php<\/code><\/p>\n\n\n\n

    php composer.php<\/code><\/p>\n\n\n\n

      \n
    1. The following message will appear:<\/li>\n<\/ol>\n\n\n\n

      “All settings correct for using Composer
      Downloading…
      Composer (version 2.3.4) successfully installed to: \/home\/zjpqumjq\/composer.phar
      Use it: php composer.phar<\/em>“<\/p>\n\n\n\n

        \n
      1. Type this line of code:<\/li>\n<\/ol>\n\n\n\n

        nano .bash_profile<\/code><\/p>\n\n\n\n

          \n
        1. Add this line of code:<\/li>\n<\/ol>\n\n\n\n

          alias composer=\"php \/home\/user\/composer.phar\"<\/code><\/p>\n\n\n\n

            \n
          1. Finally, reload the bash_profile, which will allow us to invoke the command without having to specify its path:<\/li>\n<\/ol>\n\n\n\n

            source ~\/.bash_profile<\/code><\/p>\n\n\n\n

              \n
            1. Now you just have to type “composer<\/strong>“:<\/li>\n<\/ol>\n\n\n
              \n
              \"\"<\/a><\/figure><\/div>\n\n\n

              Step 2: Installation of PHPMailer<\/h2>\n\n\n\n

              Make sure that you have installed Composer<\/strong> and that you are still connected via SSH, as explained before.<\/p>\n\n\n\n

                \n
              1. Create the desired folder for PHPMailer:<\/li>\n<\/ol>\n\n\n\n

                mkdir mail_app<\/code><\/p>\n\n\n\n

                  \n
                1. Move to the active current working directory (CWD):<\/li>\n<\/ol>\n\n\n\n

                  cd mail_app<\/code><\/p>\n\n\n\n

                    \n
                  1. Install PHPMailer with the Composer command:<\/li>\n<\/ol>\n\n\n\n

                    composer require phpmailer\/phpmailer<\/code><\/p>\n\n\n\n

                      \n
                    1. Here is the output of Composer for the installation of php_mailer:<\/li>\n<\/ol>\n\n\n
                      \n
                      \"\"<\/a><\/figure><\/div>\n\n\n
                        \n
                      1. Here, there is nothing to reload normally. It is in the script that we must indicate the path to PHPMailer:<\/li>\n<\/ol>\n\n\n\n
