显示过去几天的结果

Question

我尝试使用php和mysql获取最近7天的记录。 我将结果保存为数据库dd-mm-yyyy格式。

$start = date('d-m-Y',strtotime('-7 days'));
$end = date('d-m-Y',strtotime('now'));

mysqli_query($link, "SELECT count(*) FROM `registration_form` WHERE `appointment_date` BETWEEN '$start' and '$end' and `registration_type` = 'provisional_registration'"));

从这段代码中，我获得了过去7天的记录，但有一段时间它无法给出准确的结果。

Answer 1

尝试这个..

$date = date('Y-m-d',time()-(7*86400)); 

$sql = "SELECT * FROM registration_form WHERE appointment_date <='$date' ";

Answer 2

您也可以尝试以下方法：

mysqli_query($link, "SELECT count(*) FROM `registration_form` WHERE `appointment_date` BETWEEN NOW() and DATE_SUB(NOW(), INTERVAL 7 DAY) and `registration_type` = 'provisional_registration'");
