Are you sure $module->getInfo('name', 's') of type false|mixed|string can be used in concatenation?

$errs was never initialized. Although not strictly required by PHP, it is generally a good practice to add $errs = array(); before regardless.

The call to XoopsModule::getInfo() has too many arguments starting with 's'.

        if ($module->getInfo('image') !== false && trim($module->getInfo('image')) != '') {

It seems like $module->getInfo('image') can also be of type array; however, parameter $string of trim() does only seem to accept string, maybe add an additional type check?

Are you sure $module->getInfo('version') of type array|string can be used in concatenation?

        if (false === $module_handler->delete($module)) {

It seems like $module can also be of type false; however, parameter $module of XoopsModuleHandler::delete() does only seem to accept XoopsObject, maybe add an additional type check?

            $msgs[] = '&nbsp;&nbsp;<span style="color:#ff0000;">' . sprintf(_AM_SYSTEM_MODULES_DELETE_ERROR, $module->getVar('name')) . '</span>';

It seems like $module->getVar('name') can also be of type array and array; however, parameter $values of sprintf() does only seem to accept double|integer|string, maybe add an additional type check?

            $templates       = $tplfile_handler->find(null, 'module', $module->getVar('mid'));

The method find() does not exist on XoopsObjectHandler. It seems like you code against a sub-type of XoopsObjectHandler such as XoopsTplfileHandler or XoopsPersistableObjectHandler.
