getting a date array from a mysql database?

Question

I have a database with date field is this format "2010.06.11. | 10:26 13"

What is need is a php array that would hold all the different dates, .ie

array[0] = "2010.06.09."

array[1] = "2010.06.10."

array[2] = "2010.06.11."

Currently I am doing it by selecting the whole table, then looping through the result and adding the date substr to an array if it is not already there.

But maybe there is a faster way? Thanks.

您可以直接从数据库中仅选择不同的日期：

SELECT DISTINCT SUBSTRING(date, 1, 11) AS date_string FROM table
