phpenmod:tldr:ecb7a

This command is used in Unix-like systems with sudo (superuser) permissions to enable specific PHP modules.

• sudo: It is a command that allows a user with the necessary rights to execute another command as the superuser or another user.
• phpenmod: It is a command used to enable PHP modules, which are additional extensions that provide extra functionality to PHP.
• -v ${7-3}: -v is an option that specifies the PHP version to be used. ${7-3} is a bash variable substitution that means if the variable $7 is set, use its value; otherwise, use the value 3.
• -s ${cli}: -s is an option to specify the PHP SAPI (Server Application Programming Interface). ${cli} is another bash variable substitution where the value of the cli variable is used.
• ${json}: ${json} is a bash variable that holds the name of a specific PHP module to be enabled.

Overall, this command enables a PHP module with a specific version and SAPI configuration. The values for PHP version and SAPI are determined by the variables $7 and cli respectively, and the module to be enabled is specified by the json variable.
