Drupal get module info?

Question

Is there any function in Drupal like get_module_info('MODULE_NAME') or I should parse info file?

Answer 1

drupal_parse_info_file is the closest function, but it takes a file path, not a module name, so you have to convert the name into the path first:

$path = drupal_get_path('module', $name) . '/' . $name . '.info'
$info = drupal_parse_info_file($path);

Answer 2

If you happen to be using the Features module, it has created a solid structure for interacting with the System table that is readily adaptable for any module info gathering.

To get information about a module, use features_get_modules($module_name). This dispatches a module-specific request to features_get_info() on line 475 of features.module.

The information is cached, and you can make use of hook_system_info_alter() to modify the values you need. Note that this functionality is not touched by anything in Drupal core, and is only useful for your own custom module functionality.
