Getting the data for each month - php

Question

So what I want to do is basically this:
Month and Year:
-All the data sent on that month and year
For example:
February 2013:
-The posts on this date
March 2013:
-The posts on this date
and so on.
I have a date column on my table and it has the following format: day.month.year
I am using PHP and MySQL.
I have my own MVC framework that I'm using. I will simplify it to make it more understanble here. The function to fetch data:
function selectAll($sql){
$find = $this->prepare($sql);
$find->execute();
$fetchdata = $find->fetchAll(PDO::FETCH_ASSOC);
return $fetchdata;
}
And the code to get the dates :
$sql = "Select YEAR(Date) AS year, MONTH(Date) AS month, Headline from blog";
$data = $this->db->selectAll($sql);
foreach($data as $key => $value) {
$date[] = $value['month'].'.'.$value['year'];
}
$dateunique = array_unique($date);
This give me the results for the dates but I cannot figure out how to put the correct data under each date.

Answer 1

Convert the varchar date field into exact date using
str_to_date function
Using DATE_FORMAT you can select month wise record
Where $input is %Y-%m format // ex: 02-2013-> feb 2013
SELECT * FROM `table`
WHERE DATE_FORMAT(str_to_date(`date_column`, '%d/%m/%Y'), '%Y-%m')= '".$input."';

Answer 2

Use DATE_FORMAT mysql function.
Example
SELECT DATE_FORMAT(date_field,'%M') as Month,DATE_FORMAT(date_field,'%Y') as Year FROM table_name
and then debug result of query you will see two extra column for month and year then display it as your desire.
if date_field is varchar then use str_to_date mysql function.
SELECT STR_TO_DATE(date_field,'%M') as Month, STR_TO_DATE(date_field,'%Y') as Year FROM table_name;
OP question update
Try GROUP_CONCAT
SELECT
*,
GROUP_CONCAT(created) AS month
FROM
table_name
GROUP BY MONTH(created) DESC;
