I am creating time stamps in PHP using time();
I have the $current_time and $purchase_time. How do I make sure that purchase_time is less than 24 hours of current time?
If they are UNIX timestamps, then you can calculate this by yourself really easy, as they are seconds.
$seconds = $current_time - $purchase_time
$hours = floor($seconds/3600);
if ($hours < 24){
//success
}
Since UNIX timestamps are just numbers of seconds, just use the difference:
$purchasedToday = $current_time - $purchase_time < 24 * 60 * 60;
if ($purchasedToday) {
echo 'You just bought the item';
} else {
echo 'You bought the item some time ago';
}
You can construct a DateTime object and then use it's diff() method to calculate the difference between $current_time and $purchase_time:
$currentTime = new DateTime();
$purchaseTime = new DateTime('2011-10-14 12:34:56');
// Calculate difference:
$difference = $currentTime->diff($purchaseTime);
if ($difference->days >= 1) {
echo 'More than 24 hours ago.';
}
This is more reliable than calculating the difference yourself, as this method takes care of timezones and daylight saving time.
Something like this:
$difference=time() - $last_login;
I had use something like this:
<?php
if(date("U", strtotime("-24 hours", $current_time) > date("U", $purchase_time)) {
echo "More then 24 hours you purchased this radio";
}
?>
This works even if the time stamp not is a UNIX-timestamp.

Lets say I have a date-time object 2015-12-31T12:59. Is there a way in PHP to find the difference between current date-time and the above date-time object in seconds? Basically, is there a way to find out the time in seconds from this very moment till the date-time specified by a future date-time object?
I did some digging and found out that there's a DateTime class in PHP, but I'm not sure whether it takes a format like 2015-12-31T12:59 as input.
You can use date() function to convert your date into the number of seconds since the Unix Epoch then you can substract the actual number of seconds since the Unix Epoch.
$myDate = date('2015-12-31T12:59'); //convert your date in seconds
$now = time(); //convert now in seconds
$numberOfSeconds = $myDate - $now; //make the difference
Note:
Unix Epoch = January 1 1970 00:00:00 GMT
Dates on Unix systems can be stored in Epoch format (eg number of seconds from 1970-01-01 00:00:00).
The time() function does this naturally and other dates can be converted with something like strtotime(). All you have to do is subtract one from the other to get the time difference in seconds
you can try using this way this result will give the difference in sec,min,hr,days...
//use this way-----------------------
$c_time=//your current time
$date_current_time = date('Y-m-d H:i:s');
$datetime1 = new DateTime($c_time);
$datetime2 = new DateTime($date_current_time);
$difference = $datetime1->diff($datetime2);
$f6=$difference->y.' Y ';
$f5=$difference->m.' M';
$f4=$difference->d.' D';
$f3=$difference->h.' hr';
$f2=$difference->i.' min';
$f1=$difference->s.' sec';
if($f2==0 && $f3==0 && $f4==0 && $f5==0 && $f6==0)
{
if($f1<=20)
{
$time=" few sec ago";
}
else if($f1>20)
{
$time=$f1." ago";
}
}
else if($f3==0 && $f4==0 && $f5==0 && $f6==0)
{
if($f2<=2)
{
$time=" few min ago";
}
else if($f2>2)
{
$time=$f2." ago";
}
}
else if($f4==0 && $f5==0 && $f6==0)
{
$time=$f3." ago";
}
else if($f5==0 && $f6==0)
{
$time=$f4." ago";
}
else if($f6==0)
{
$time=$f5." ago";
}
else
{
$time=$f6." ago";
}
may this will help...to get the difference of time
i use ths method to find the difference between two timestamp and get the number of seconds between those two times, and i refresh the information with jquery like a counter.
$diff = strtotime(date('Y-m-d H:i:s')) - strtotime('2014-06-25 14:50:03');
$time = intval(date('s', $diff));
echo $time;
When the difference is more than 60 seconds, the $time comes back to 0, like a reset.
i would like to display 1 min XX s for example
The s flag for date() will never return a value greater than 59 as it only represents the current number of seconds of a given time which can never be more than 59 before rolling over into a new minute.
If you want the total number of seconds you can actually remove your second line of code as the difference between two Unix Timestamps is always in seconds:
$time = strtotime(date('Y-m-d H:i:s')) - strtotime('2014-06-25 14:50:03');
echo $time;
If you want to display this as minutes and seconds you can use DateTime() which offers better tools for this:
$now = new DateTime();
$then = new DateTime('2014-06-25 14:50:03');
$diff = $now->diff($then);
echo $diff->format('%i minutes %s seconds');
format the date
$diff = strtotime(date('Y-m-d H:i:s')) - strtotime('2014-06-25 14:50:03');
$time = date('i:s', $diff);
echo $time;
Pass time like 1 & now 2
function diffrencePassTimeAction($DataTime){
$im = $DataTime - strtotime("now");
return $im;
}
Future time like 2 & now 1
function diffrenceFuturTimeAction($DataTime){
$im = strtotime("now") - $DataTime;
return $im;
}
this function delete (-less)
function diffrencePassTimeAction($DataTime){
if ($DataTime > 0)
return $DataTime - strtotime("now");
else
return strtotime("now"); // OR return 0;
}
Let's say I got this time 21:07:35 now and this time into a variable 21:02:37 like this
<?php
$current_time = "21:07:35";
$passed_time = "21:02:37";
?>
Now I want check if $current_time is less than 5 minutes then echo You are online
So how can I do this in PHP?
Thanks
:)
To compare a given time to the current time:
if (strtotime($given_time) >= time()+300) echo "You are online";
300 is the difference in seconds that you want to check. In this case, 5 minutes times 60 seconds.
If you want to compare two arbitrary times, use:
if (strtotime($timeA) >= strtotime($timeB)+300) echo "You are online";
Be aware: this will fail if the times are on different dates, such as 23:58 Friday and 00:03 Saturday, since you're only passing the time as a variable. You'd be better off storing and comparing the Unix timestamps to begin with.
$difference = strtotime( $current_time ) - strtotime( $passed_time );
Now $difference holds the difference in time in seconds, so just divide by 60 to get the difference in minutes.
Use Datetime class
//use new DateTime('now') for current
$current_time = new DateTime('2013-10-11 21:07:35');
$passed_time = new DateTime('2013-10-11 21:02:37');
$interval = $current_time->diff($passed_time);
$diff = $interval->format("%i%");
if($diff < 5){
echo "online";
}
$my_time = "3:25:00";
$time_diff = strtotime(strftime("%F") . ' ' .$my_time) - time();
if($time_diff < 0)
printf('Time exceeded by %d seconds', -$time_diff);
else
printf('Another %d seconds to go', $time_diff);
I have an simple question about how to set date based on time range. This is my code so far:
date_default_timezone_set("Asia/Jakarta");
$time = date("G:i");
if ($time >= 8:00)
{
echo date("j-F-Y");
}
else
{
echo date("j-F-Y", time() - 60 * 60 * 24);
}
Example today is 29-Apr-2013.
Now I want before time 8:00 the date will still 28-Apr-2013. After that, date will continue to 29-Apr-2013.
The code is successfully complete the rule, if time before 8:00. But if I changed my computer time to be 11:00 or etc, it will set yesterday back.
$time = date("G:i");
if ($time >= 8:00)
This comparison is not good. Try numerically like
$time = intval(date("Gi"));
if ($time >= 800)
I have a Date object ( from Pear) and want to subtract another Date object to get the time difference in seconds.
I have tried a few things but the first just gave me the difference in days, and the second would allow me to convert one fixed time to unix timestamp but not the Date object.
$now = new Date();
$tzone = new Date_TimeZone($timezone);
$now->convertTZ($tzone);
$start = strtotime($now);
$eob = strtotime("2009/07/02 17:00"); // Always today at 17:00
$timediff = $eob - $start;
** Note ** It will always be less than 24 hours difference.
Still gave somewhat wrong values but considering I have an old version of PEAR Date around, maybe it works for you or gives you an hint on how to fix :)
<pre>
<?php
require "Date.php";
$now = new Date();
$target = new Date("2009-07-02 15:00:00");
//Bring target to current timezone to compare. (From Hawaii to GMT)
$target->setTZByID("US/Hawaii");
$target->convertTZByID("America/Sao_Paulo");
$diff = new Date_Span($target,$now);
echo "Now (localtime): {$now->format("%Y-%m-%d %H:%M:%S")} \n\n";
echo "Target (localtime): {$target->format("%Y-%m-%d %H:%M:%S")} \n\n";
echo $diff->format("Diff: %g seconds => %C");
?>
</pre>
Are you sure that the conversion of Pear Date object -> string -> timestamp will work reliably? That is what is being done here:
$start = strtotime($now);
As an alternative you could get the timestamp like this according to the documentation
$start = $now->getTime();
To do it without pear, to find the seconds 'till 17:00 you can do:
$current_time = mktime ();
$target_time = strtotime (date ('Y-m-d'. ' 17:00:00'));
$timediff = $target_time - $current_time;
Not tested it, but it should do what you need.
I don't think you should be passing the entire Date object to strtotime. Use one of these instead;
$start = strtotime($now->getDate());
or
$start = $now->getTime();
Maybe some folks wanna have the time difference the facebook way. It tells you "one minute ago", or "2 days ago", etc... Here is my code:
function getTimeDifferenceToNowString($timeToCompare) {
// get current time
$currentTime = new Date();
$currentTimeInSeconds = strtotime($currentTime);
$timeToCompareInSeconds = strtotime($timeToCompare);
// get delta between $time and $currentTime
$delta = $currentTimeInSeconds - $timeToCompareInSeconds;
// if delta is more than 7 days print the date
if ($delta > 60 * 60 * 24 *7 ) {
return $timeToCompare;
}
// if delta is more than 24 hours print in days
else if ($delta > 60 * 60 *24) {
$days = $delta / (60*60 *24);
return $days . " days ago";
}
// if delta is more than 60 minutes, print in hours
else if ($delta > 60 * 60){
$hours = $delta / (60*60);
return $hours . " hours ago";
}
// if delta is more than 60 seconds print in minutes
else if ($delta > 60) {
$minutes = $delta / 60;
return $minutes . " minutes ago";
}
// actually for now: if it is less or equal to 60 seconds, just say it is a minute
return "one minute ago";
}
