phpdismod:tldr:2f257

This command is a command-line instruction to disable specific PHP modules. Here's a breakdown of each element:

• sudo: The command is prefixed with sudo to run it as a superuser (root) or with administrative privileges. This is necessary because module management typically requires elevated permissions.
• phpdismod: This is the main command used to disable PHP modules.
• -v ${7-3}: The -v flag instructs phpdismod to operate in verbose mode, providing more detailed output. ${7-3} is a variable indicating the PHP version to target for module removal. It specifies the PHP major version (7) and minor version (3), which can be customized as needed.
• -s ${cli}: The -s flag specifies the PHP SAPI (Server Application Programming Interface) to affect. ${cli} is a variable representing the command-line interface (CLI) SAPI, indicating that the module should be disabled specifically for command-line PHP usage. Other possible values for this variable could be ${apache2} for the Apache web server module or ${fpm} for PHP-FPM (FastCGI Process Manager).
• ${json}: This variable represents the name of the specific PHP module to disable. Replace ${json} with the desired module name.

Overall, the command is used to disable a PHP module with administrative privileges, specifying the PHP version, SAPI, and module to disable.
