顯示過去幾天的結果

Question

我嘗試使用php和mysql獲取最近7天的記錄。 我將結果保存為數據庫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'"));

從這段代碼中，我獲得了過去7天的記錄，但有一段時間它無法給出准確的結果。

Answer 1

嘗試這個..

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

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

Answer 2

您也可以嘗試以下方法：

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'");
