Collect a list of all loaded modules. During the bootstrap, return only vital modules. See bootstrap.inc

Parameters

$refresh: Whether to force the module list to be regenerated (such as after the administrator has changed the system settings).

$bootstrap: Whether to return the reduced set of modules loaded in "bootstrap mode" for cached pages. See bootstrap.inc.

$sort: By default, modules are ordered by weight and filename, settings this option to TRUE, module list will be ordered by module name.

$fixed_list: (Optional) Override the module list with the given modules. Stays until the next call with $refresh = TRUE.

Return value

An associative array whose keys and values are the names of all loaded modules.
