function variable_set

Sets a persistent variable.

Case-sensitivity of the variable_* functions depends on the database collation used. To avoid problems, always use lower case for persistent variable names.

This function is deprecated in Backdrop and will be removed in a future release. Variables are not managed through the configuration system, so they cannot be moved between environments safely. If your module needs to save configuration settings, use config_set() instead. If you need to save an environment-specific setting (such as the last time cron ran), use state_set() instead.

Parameters

$name: The name of the variable to set.

$value: The value to set. This can be any PHP data type; these functions take care of serialization as necessary.
