I would add the New text if one day is not passed but if it is passed i would delete the text New if one day is passed.
I tried this code :
<?php
$farkZaman = time() - strtotime("2017-09-26 19:00:00");
$farkGun = floor($farkZaman / (60 * 60 * 24));
if($farkGun < 1){
echo "Yeni";
}
?>
How can i do ?
I need your help.
Note : I have French but i don't have a good English.
Don't know if this is what you are looking for.
Here is set $dt as tomorrow with a time (about 24 hours from now GMT+1).
Then I compare if time is less than this time.
If it is I echo the text.
$dt = strtotime("2017-09-29 06:40");
If(time()<=$dt){
Echo "the text";
}
You can do something like this.
if(strtotime($date_variable) > strtotime("-1 day")) {
echo "New";
}
Try like this
<?php
$now = new DateTime();
$now->format('Y-m-d H:i:s');
$created_date = new DateTime(date('Y-m-d', strtotime("2017-09-27 13:00:00")));
$day = $created_date->diff($now)->days; // 0
if($day < 1){
echo "new texts";
}
?>

How can I compare two dates in PHP?
The date is stored in the database in the following format
2011-10-2
If I wanted to compare today's date against the date in the database to see which one is greater, how would I do it?
I tried this,
$today = date("Y-m-d");
$expire = $row->expireDate //from db
if($today < $expireDate) { //do something; }
but it doesn't really work that way. What's another way of doing it?
If all your dates are posterior to the 1st of January of 1970, you could use something like:
$today = date("Y-m-d");
$expire = $row->expireDate; //from database
$today_time = strtotime($today);
$expire_time = strtotime($expire);
if ($expire_time < $today_time) { /* do Something */ }
If you are using PHP 5 >= 5.2.0, you could use the DateTime class:
$today_dt = new DateTime($today);
$expire_dt = new DateTime($expire);
if ($expire_dt < $today_dt) { /* Do something */ }
Or something along these lines.
in the database the date looks like this 2011-10-2
Store it in YYYY-MM-DD and then string comparison will work because '1' > '0', etc.
Just to compliment the already given answers, see the following example:
$today = new DateTime('');
$expireDate = new DateTime($row->expireDate); //from database
if($today->format("Y-m-d") < $expireDate->format("Y-m-d")) {
//do something;
}
Update:
Or simple use old-school date() function:
if(date('Y-m-d') < date('Y-m-d', strtotime($expire_date))){
//echo not yet expired!
}
I would'nt do this with PHP.
A database should know, what day is today.( use MySQL->NOW() for example ), so it will be very easy to compare within the Query and return the result, without any problems depending on the used Date-Types
SELECT IF(expireDate < NOW(),TRUE,FALSE) as isExpired FROM tableName
$today = date('Y-m-d');//Y-m-d H:i:s
$expireDate = new DateTime($row->expireDate);// From db
$date1=date_create($today);
$date2=date_create($expireDate->format('Y-m-d'));
$diff=date_diff($date1,$date2);
//echo $timeDiff;
if($diff->days >= 30){
echo "Expired.";
}else{
echo "Not expired.";
}
Here's a way on how to get the difference between two dates in minutes.
// set dates
$date_compare1= date("d-m-Y h:i:s a", strtotime($date1));
// date now
$date_compare2= date("d-m-Y h:i:s a", strtotime($date2));
// calculate the difference
$difference = strtotime($date_compare1) - strtotime($date_compare2);
$difference_in_minutes = $difference / 60;
echo $difference_in_minutes;
You can convert the dates into UNIX timestamps and compare the difference between them in seconds.
$today_date=date("Y-m-d");
$entered_date=$_POST['date'];
$dateTimestamp1 = strtotime($today_date);
$dateTimestamp2 = strtotime($entered_date);
$diff= $dateTimestamp1-$dateTimestamp2;
//echo $diff;
if ($diff<=0)
{
echo "Enter a valid date";
}
I had that problem too and I solve it by:
$today = date("Ymd");
$expire = str_replace('-', '', $row->expireDate); //from db
if(($today - $expire) > $NUMBER_OF_DAYS)
{
//do something;
}
Here's my spin on how to get the difference in days between two dates with PHP.
Note the use of '!' in the format to discard the time part of the dates, thanks to info from DateTime createFromFormat without time.
$today = DateTime::createFromFormat('!Y-m-d', date('Y-m-d'));
$wanted = DateTime::createFromFormat('!d-m-Y', $row["WANTED_DELIVERY_DATE"]);
$diff = $today->diff($wanted);
$days = $diff->days;
if (($diff->invert) != 0) $days = -1 * $days;
$overdue = (($days < 0) ? true : false);
print "<!-- (".(($days > 0) ? '+' : '').($days).") -->\n";
Found the answer on a blog and it's as simple as:
strtotime(date("Y"."-01-01")) -strtotime($newdate))/86400
And you'll get the days between the 2 dates.
This works because of PHP's string comparison logic. Simply you can check...
if ($startdate < $date) {// do something}
if ($startdate > $date) {// do something}
Both dates must be in the same format. Digits need to be zero-padded to the left and ordered from most significant to least significant. Y-m-d and Y-m-d H:i:s satisfy these conditions.
If you want a date ($date) to get expired in some interval for example a token expiration date when performing a password reset, here's how you can do:
$date = $row->expireDate;
$date->add(new DateInterval('PT24H')); // adds 24 hours
$now = new \DateTime();
if($now < $date) { /* expired after 24 hours */ }
But in your case you could do the comparison just as the following:
$today = new DateTime('Y-m-d');
$date = $row->expireDate;
if($today < $date) { /* do something */ }
first of all, try to give the format you want to the current date time of your server:
Obtain current date time
$current_date = getdate();
Separate date and time to manage them as you wish:
$current_date_only = $current_date[year].'-'.$current_date[mon].'-'.$current_date[mday];
$current_time_only = $current_date['hours'].':'.$current_date['minutes'].':'.$current_date['seconds'];
Compare it depending if you are using donly date or datetime in your DB:
$today = $current_date_only.' '.$current_time_only;
or
$today = $current_date_only;
if($today < $expireDate)

In my code I pretty much send a token to the database with the
date('Y-m-d H:i:s');
function. But I am checking to see if the timestamp I sent if greater than 60 seconds if so i echo yes and else no. I keep getting no and I know its more than a minute because i time it. I've seen post about this but they're using specific dates and I am just going on when a user submits a form and checking if the token is 60 seconds old. Here is my code
php
<?php
require_once('db_login.php');
$stmtToken = $handler->prepare("SELECT * FROM email_token");
$stmtToken->execute();
$rowToken = $stmtToken->fetch();
$date = $rowToken['time_stamp'];
if($date > time() + 60) {
echo 'yes';
} else {
echo 'no';
}
?>
You can also play with dates in different manners. All four lines here are equivalent:
$now = (new \DateTime(date('Y-m-d H:i:s')))->getTimestamp();
$now = (new \DateTime('now'))->getTimestamp();
$now = (new \DateTime())->getTimestamp();
$now = time();
And then you can compare in this manner:
$tokenExpirationTimestamp = (new \DateTime($date))
->modify('+60 seconds')
->getTimestamp();
$isTokenExpired = $tokenExpirationTimestamp < time();
if ($isTokenExpired) {
// ...
}
When you compare times and dates you can either use datetime or strtotime.
Using strings will not work as expected in all cases.
In comments you mentioned how you want to compare, and you need to add the 60 seconds to the "date", not the time().
if(strtotime($date) + 60 < time()) {
I am stuck. I have a database with colummn datetime in comments table. Basicly when user adds a new comment it's inserted in this table and the datetime is stored. So what i want to do now is to check if, lets say 1 minute is passed since he last commented. But i am getting all the time true in if statement.
Well. Before posted this did the last check. Output is not as expected.
My code.
$limits = new Limits();
$user = new User();
$time = new DateTime();
$time->add(new DateInterval('PT' . 1 . 'M'));
$stamp = $time->format('Y-m-d H:i:s');
$limit = $limits->check_comment_limit($user->loggedInUser());
if($limit->time < $stamp){
echo 'Take a brake';
}
//for debugging
echo $stamp . '<br>';//2014-03-18 13:38:41
echo $limit->time; //2014-03-18 01:37:37
Ok obviusly $limit->time is smaler than $stamp. With time() it's simple, time() + 60 but how to do this with datetime?
I think this is that you want to do:
<?php
date_default_timezone_set('UTC');
// Get current datetime.
$now = new DateTime("now");
// Get last comment datetime.
$comment = new DateTime('2014-03-18 13:26:00');
// Get interval limit between comments.
$limit = new DateInterval('PT1M');
// Calculate the difference between the current and last commented datetime.
$diff = $now->diff($comment);
// Calculate the total minutes.
$minutes = $diff->days * 24 * 60;
$minutes += $diff->h * 60;
$minutes += $diff->i;
// Debug output
echo $now->format('Y-m-d H:i:s').'<br>';
echo $comment->format('Y-m-d H:i:s').'<br>';
echo $limit->i.'<br>';
echo $minutes.' minutes <br>';
// Limit smaller than difference? Next comment is allowed.
if($limit->i <= $minutes) {
echo "Your comment has been saved!";
} else {
echo "Your aren't allowed to comment now. Wait ".intval($limit->i*60 -
$diff->format('%s'))." seconds until you are allowed to comment again.";
}
?>
Edit: Added missing calculation of total minutes. Otherwise the calculation don't work with dates with the same minutes but other day or hour.
Another and much simpler/generic (working with every interval) solution would be like this:
<?php
date_default_timezone_set('UTC');
// Get current datetime.
$now = new DateTime("now");
// Get last comment datetime.
$comment = new DateTime('2014-03-18 16:45:00');
// Get and add interval limit to comments.
$limit = new DateInterval('PT1M');
$comment->add($limit);
// Debug output
echo $now->format('Y-m-d H:i:s').'<br>';
echo $comment->format('Y-m-d H:i:s').'<br>';
// Limit smaller than difference? Next comment is allowed.
if($comment <= $now) {
echo "Your comment has been saved!";
} else {
echo "Your aren't allowed to comment now. On ".$comment->format('Y-m-d H:i:s')." you
are allowed to comment again.";
}
?>
I created two datetime objects where $date1 = 09/02/2013 and $date2 = 03/02/2014
When I run the following code:
if ($date2 < $date1)
{
echo "hi";
}
for some reason it echos "hi" although $date2 is clearly greater than $date1. How am i supposed to compare these two dates? Please help!
<?php
$date1 = new DateTime ('2013-12-25');
$date2 = new DateTime ('2014-11-24');
if ($date1 > $date2) {
echo ('date1 is greater than date2');
}
else {
echo ('date2 is greater than date1');
}
use like below with function http://php.net/manual/en/function.strtotime.php
if (strtotime($date2 ) < strtotime($date1))
{
echo "hi";
}
hope this will sure help you.
That could work in JavaScript, but in PHP it will not :P
However, you could calculate an interval between dates.
$interval = $date1->diff($date2);
if ($interval->invert){ //1 if negative and 0 if positive
// $date2 has a bigger time value
} else {
// $date1 has a bigger time value
}
