The command "sudo phpenmod ${json}" is used to enable a PHP extension module in a Linux system.
Here is a breakdown of the command:
-
"sudo": Prefixing a command with "sudo" makes it run with administrative/root privileges. This is necessary because enabling PHP modules usually requires administrative access.
-
"phpenmod": This is a command in Debian-based Linux distributions (such as Ubuntu) used to enable PHP extensions. It modifies the configuration files to include the specified PHP module and activates it.
-
"${json}": This is a variable (denoted by the "$") that should contain the name of the PHP extension module to be enabled (e.g., "json"). The curly braces "{}" are used to separate the variable name from adjacent characters.
Overall, the command "sudo phpenmod ${json}" is used to enable a specific PHP extension module by modifying the PHP configuration files with administrative privileges.
