Question

我有一个简单的表单，它包含两个日期选择器。开始和结束。这个日期选择器显示mm-yy-dddd格式。但我的数据库表包含yyyy-mm-dd格式。现在我想从这个表中获取数据..如何使用mysql和php从这种格式获取数据？

 <?php

if(isset($_POST['submitted'])){
    // catch data

    $startDate = $_POST['start_date'];
    $endDate = $_POST['end_date'];



     // echo $startDate;
     // echo "<br />";
     // echo $endDate;



     $result = mysql_query('SELECT SUM(amount) AS total FROM tbl_loan WHERE (created BETWEEN "'.$startDate.'" AND "'.$endDate.'") '); 
    $row = mysql_fetch_assoc($result);
    $sum = $row['total'];


}

  ?>

使用strtotime

if(isset($_POST['submitted'])){
    // catch data

    $startDate = $_POST['start_date'];
    $endDate = $_POST['end_date'];



     // echo $startDate;
     // echo "<br />";
     // echo $endDate;



     $result = mysql_query('SELECT SUM(amount) AS total FROM tbl_loan WHERE (created BETWEEN "'.date("Y-m-d", strtotime($startDate)).'" AND "'.date("Y-m-d", strtotime($endDate)).'") '); 
    $row = mysql_fetch_assoc($result);
    $sum = $row['total'];


}

Strtotime将任何格式的日期字符串转换为unix时间戳。从那里，日期格式将其转换为指定的格式。

如何在日期选择器之间从数据库获取数据
