function ctools_static in Chaos Tool Suite (ctools) 6

Central static variable storage. Modeled after Drupal 7's drupal_static().

Parameters

$name: Globally unique name for the variable. For a function with only one static, variable, the function name (e.g. via the PHP magic __FUNCTION__ constant) is recommended. For a function with multiple static variables add a distinguishing suffix to the function name for each one.

$default_value: Optional default value.

$reset: TRUE to reset a specific named variable, or all variables if $name is NULL. Resetting every variable should only be used, for example, for running unit tests with a clean environment. Should be used only though via function ctools_static_reset().
