To danh mục just the useful Databases, và not the system ones:

$query = "SELECT schema_name FROM information_schema.schemata WHERE schema_name NOT IN ("information_schema", "mysql", "performance_schema")";$result = mysqli_query($links, $query) or die(mysqli_error($link));$dbs = array();while($db = mysqli_fetch_row($result)) $dbs<> = $db<0>;echo implode("", $dbs);Your MySquốc lộ user should have full access, otherwise you will see only the databases where you have sầu at least read permissions.

$r = mysql_query("SHOW DATABASES");while ($row = mysql_fetch_assoc($r)) print_r($row);that aught lớn bởi it
