我想比较我的表格上的最后一个日期和当前日期，但它仅比较日期和月份而不是年份。我能做些什么来比较不同年份的日期？比较不同年份的两个日期
1.db.inc.php
<?php
define('DB_NAME','ftender');
define('DB_USER','root');
define('DB_PASS','');
define('DB_HOST','localhost');

2.fun.inc.php
<?php
include_once'db.inc.php';
function connect()
{
$con = mysqli_connect('localhost','root','','ftender');
if($con!=true)
{
echo 'Connection failed';
}
else
{
mysqli_select_db($con,'ftender');
}
}
function close()
{
$con = mysqli_connect('localhost','root','','ftender');
if($con!=true)
{
echo 'Connection failed';
}
else
{
mysqli_select_db($con,'ftender');
}
mysqli_close($con);
}
function clos(){
mysql_close();
}
function query(){
$con = mysqli_connect('localhost','root','','ftender');
if($con!=true)
{
echo 'Connection failed';
}
else
{
mysqli_select_db($con,'ftender');
}
$date=date("m/d/Y");
$q="SELECT * FROM adtender where lastdate>='$date' group by tendername";
$myData=mysqli_query($con,$q);
while($record=mysqli_fetch_array($myData,MYSQLI_ASSOC)){
echo '<option value="' . $record['tendername'] . '">' . $record['tendername'] . '</option>';
}
}
function fill(){
$myID=mysql_query("SELECT * FROM adtender");
while($r=mysql_fetch_array($myID)){
echo '<option value="' .$r['tenderid'] .'">' . $r['tenderid'] . '</option>';
}
}

此编码被比较2个日期正确无需考虑年份。
'日期（ “米/ d/Y”）'是不是一个有效的MySQL日期格式。什么是列类型？如果它不是'datetime'，你应该切换到那个。现在看起来你正在比较字符串而不是日期。 – jeroen
尝试在查询中使用'BETWEEN'。 –
HTML代码对于这个问题是完全无关紧要的，同样是你发布的3/4的PHP代码。请提供[mcve]。如果问题与MySQL相关，则将其添加为标签。 – axiac
