function variable_set in Drupal 6

Same name and namespace in other branches

1. 4 includes/bootstrap.inc \variable_set()
2. 5 includes/bootstrap.inc \variable_set()
3. 7 includes/bootstrap.inc \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.

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.
