如何找到當前的時間戳和登錄日期

Question

可能重複之間的天數：
How to calculate the difference between two dates using PHP?
How to find number of days between two dates using php
How to find the dates between two specified date?

我有我的表中的三個字段

seeker 
name ....current_time.... login_date 

second field i have created through timestamp phpmyadmin 
type: timestamp 
default: current_timestamp 

當導引頭到網站註冊自己的current_time通過時間戳

third field is login_date filed. when user logins then this field is updated 

//login date 
$login_date = date("Y-m-d"); 
echo "login date"."".$login_date; 
$qry1 = "update seeker set login_date = '$login_date' where name='$uname'"; 
$res1=mysql_query($qry1,$con); 

now current_date is like 
"2012-04-10 21:58:01" 

and login_date is like 
"2012-05-02" 

我想找到這兩個日期之間的天數自動插入。我不知道如何，因爲CURRENT_DATE包括時間太長減去這些日期..或是否有任何其他的方式來排除當前最新的時間，即進入只有日期沒有時間

Answer 1

$login_date = strtotime(x); // change x with your login date var 
$current_date = strtotime(y); // change y with your current date var 
$datediff = $current_date - $login_date; 
$days = floor($datediff/(60*60*24));
