Answer 1

It makes with one query in MySQL, without any PHP:

SELECT * FROM `table_name`
WHERE DATE(`date_post`) >= DATE_FORMAT(CURDATE() - INTERVAL 1 MONTH, CONCAT('%Y-%m-', DAY(LAST_DAY(CURDATE() - INTERVAL 1 MONTH))))
AND DATE(`date_post`) <= DATE_FORMAT(CURDATE() + INTERVAL 1 MONTH, '%Y-%m-01');
