Array
(
    [university] => 57
    [iit] => 57
    [jee] => 44
    [application] => 28
    [study] => 26
    [college] => 23
    [exam] => 19
    [colleges] => 19
    [view] => 19
    [amp] => 18
)

如何获得前5个元素的数组？

如何在WHERE中使用DISTINCT子句？例如:

SELECT * FROM table WHERE DISTINCT email; -- email is a column name

我想从具有不同电子邮件地址的表中选择所有列.
