如何从以秒为单位的时间请求计算2小时 - how to calculate 2 hours from the time request made in seconds

how to calculate 2 hours from the time request made in seconds

我的服务器时间是GMT，所以我将其转换为亚洲/吉隆坡时间。我需要计算当前时间和提出请求的时间之间的时间差。发出的时间请求存储在数据库中，并在$reset_req变量中检索。

$reset_req="2015-06-30 11:30:23";   
$timezone_offset = +8; // us central time (gmt-6) for me
if(isset($reset_req)){
 $request_date2 = strtotime($reset_req)+$timezone_offset*60*60;
}
echo "current time= ".strtotime(time());
echo"<br/>";
echo "time req made=".strtotime($request_date2);
echo"<br/>";
  $timediff = strtotime(time()) - strtotime($request_date2); // in seconds
if($timediff < 2 hours)//how to calculate 2 hours here
{
//do something
}

每个人都已经说过如何计算2小时（2*3600秒）。但他们没有告诉你的是，你不能这样做：strtotime(time());time();已经给了你一个Unix时间戳，所以你不能转换两次。

你的代码应该更像这个

<?php
$reset_req = "2015-06-30 11:30:23";   
$timezone_offset = +8; // us central time (gmt-6) for me
if(isset($reset_req)){
      $request_date2 = strtotime($reset_req)+$timezone_offset*60*60;
      $current = time();
} else {
      echo '$reset_req was not set';
      exit;
}
echo "current time= " . $current . "<br />";
echo "time req made=" . $request_date2 . "<br />";
$timediff = $current - $request_date2; // in seconds
if($timediff < (2*3600))//how to calculate 2 hours here
{
    echo "less than 7200 sec have past since $request_date2. Past: $timediff seconds";    
}else{
    echo "more than 7200 sec have past since $request_date2. Past: $timediff seconds";   
}
?>

$hour = 3600; //an hour has 3600 seconds
if($timediff < 2 * $hour )
{
//do something
}

$timediff以秒为单位。所以你必须将其转换为小时或将2小时转换为秒，然后需要进行如下比较：

更换

if($timediff < 2 hours)//how to calculate 2 hours here
{
 //do something
}

带有

if($timediff < (2*3600))//how to calculate 2 hours here
{
 //do something
}

试试这个

<?php
$reset_req = "2015-06-30 11:30:23"; 
//set default timezone here
date_default_timezone_set("Asia/Kuala_Lumpur");
$request_date2 = '';
if(isset($reset_req))
{
    $request_date2 = strtotime($reset_req);
}
echo "Current time = ".time();
echo"<br/>";
echo "Time req made =".$request_date2;
echo"<br/>";
$timediff = time() - $request_date2; // in seconds
echo "<br>Time Differnce : ".$timediff;
//how to calculate 2 hours here
if($timediff < 2*3600)
{
    //do something
}
?>
