在MYSQL數據庫中連接PHP變量DATETIME

Question

我從Datepicker Jquery UI獲取DATE變量，並將其作爲變量包含在MYSQL語句中。但select不適用於該變量。什麼原因 ？

下面的代碼

$fromDate = new DateTime($from); 
$toDate = new DateTime($to); 

$fromDate2 = mysqli_real_escape_string($fromDate); 
$toDate2 = mysqli_real_escape_string($toDate); 

$sql = mysqli_query($mySqlConnect,"SELECT * FROM 1398_log WHERE date BETWEEN $fromDate2 AND $toDate2 ORDER by id DESC"); 

此選擇確定：

$sql = mysqli_query($mySqlConnect,"SELECT * FROM 1398_log WHERE date BETWEEN '2016-03-01 00:00:00' AND '2016-06-30 23:59:59'ORDER by id DESC"); 

Answer 1

您需要提供的日期在SQL字符串：

$sql = mysqli_query($mySqlConnect,"SELECT * 
FROM 1398_log 
WHERE date BETWEEN '$fromDate2' AND '$toDate2' 
ORDER by id DESC");
