require_once($CFG->dirroot .'/course/lib.php');
require_once($CFG->libdir .'/filelib.php');

//redirect_if_major_upgrade_required(); 

$person               = new StdClass();
$person->id           = 10370;
$person->password     = hash_internal_user_password('xinxin123');

$DB->update_record('user', $person);

require_once('config.php');

require_once($CFG->dirroot .'/course/lib.php');
require_once($CFG->libdir .'/filelib.php');

//redirect_if_major_upgrade_required(); 

$DB->delete_records('user', array('id'=>10546));
复制代码

Php代码
require_once('config.php');
require_once('../lib/functions.php');
require_once('../lib/array2xml.php');

$conditions = array();
$sort       = 'id desc';
$fields     = 'id,username,firstname,lastname,email,lastlogin,lastip';
$limitfrom  = 0;
$limitnum   = 30;

$students['students'] = objectToArray($DB->get_records('user', $conditions, $sort, $fields, $limitfrom, $limitnum));
//echo '
'; print_r($students);
//echo JSON($students);

header( 'Content-Type:text/html;charset=utf-8');
header('Content-type: text/xml'); 
exit(array2xml($students));
