I have a week calendar that holds events, and want that users can't add events for the past days. So I'm tring to use a function like that:
if( strtotime($this->day) < time() ){ // date format is YYYY-MM-DD
// date is past
}else{
// date is not past
}
It seems to works fine, except that it consider today date as a past day. What am i doing wrong?
Simpler ->
if(strtotime($this->day) < strtotime(date('Y-m-d')))
{
...
}
else
{
...
}
A timestamp never contains only the date, but is always down to the current second. strtotime($this->day) is going to return today's date at 0:00, while you are comparing it against now, say, 11:12.
You could use strtotime("$this->day 12:59:59pm"); (if the format of $this->day allows for that) or use tomorrow's timestamp.
if(strtotime($this->day) < mktime(0, 0, 0)){
// date is past
} else {
// date is not past
}

I need to know if a date is in the current month.
Examples:
If the date is 2018-06-30 and current month is June (06), then true.
If the date is 2018-07-30 and current month is June (06), then false.
I have a list of dates with more than 1000 dates and I want to show or colorize only the dates that belongs to a current month.
You can do it all on one line. Basically convert the date in question to a PHP time, and get the month.
date('m',strtotime('2018-06-30' )) == date('m');
Using the date() function, if you pass in only the format, it'll assume the current date/time. You can pass in a second optional variable of a time() object to use in lieu of the current date/time.
I hope this helps -
$date = "2018-07-31";
if(date("m", strtotime($date)) == date("m"))
{
//if they are the same it will come here
}
else
{
// they aren't the same
}
As an alternative you could use a DateTime and for the format use for example the n to get the numeric representation of a month without leading zeros and use Y to get the full numeric representation of a year in 4 digits.
$d = DateTime::createFromFormat('Y-m-d', '2018-06-30');
$today = new DateTime();
if($d->format('n') === $today->format('n') && $d->format('Y') === $today->format('Y')) {
echo "Months match and year match";
}
Test
PHP doesn't implement a date type. If you are starting with a date/time and you know that your you are only dealing with a single timezone, AND you mean you want the current month in the curent year
$testdate=strtotime('2018-06-31 12:00'); // this will be converted to 2018-07-01
if (date('Ym')==date('Ym', $testdate)) {
// current month
} else {
// not current month
}
Im having some bizarre results in regards to the php date() function. Basically Im getting a date from a Mysql database which is in a string format, split into three elements. This would be Day, Month, Year (15 september 2012 for example) Im ultimately comparing two dates to see if it has expired. But the issue is that only certain dates are allowing the code to work, and some do not work at all (or allow the if statement to work effectively) Below is my code, any help would be great.
$today = date("d-m-Y");
$expire = date("d-m-Y",strtotime($this->getData('date_day')."-".
$this->getData('date_month')."-".$this->getData('date_year'))) ;
if ($expire < $today)
{
echo 'expired';
}
else
{
echo 'Not expired';
}
Im sure its something simple, but for some reason I cannot solve it.
You need to compare the Unix timestamps.
$today = time();
$expire = strtotime($this->getData('date_day')."-".
$this->getData('date_month')."-".$this->getData('date_year')) ;
if ($expire > $today)
{
echo 'expired';
}
else
{
echo 'Not expired';
}
It looks like strtotime is expected a US date format; you need to swap the month and the day around to generate a valid date:
$today = date("d-m-Y");
$expire = date("d-m-Y",strtotime($this->getData('date_month')."-".
$this->getData('date_day')."-".$this->getData('date_year'))) ;
On the other hand, see Stephen305's answer - it's a much better solution to your problem.
I am using the following code to attempt to compare the current date with a date entry in a mySql database. It's code that I have found online and adapted as all the examples I have found hard-code the date to compare the current date with.
The trouble is even dates in the future are being marked as expired and I can't understand why this would be.
I am afraid that I am still new to PHP, so I may be making a schoolboy error!
$exp_date = KT_formatDate($row_issue_whatson1['dateToShow']);
$todays_date = date("d-m-Y");
$today = strtotime($todays_date);
$expiration_date = strtotime($exp_date);
if ($expiration_date > $today) { echo "Not expired"; } else { echo "expired"; }
Any help would be most appreciated.
I should add that the date time format used in the database entries is dd/mm/yyyy
Instead of making a string then converting it to a timestamp, simply use mktime:
<?php
$today = mktime(
0, // hour
0, // minute
0 // seconds
);
?>
The rest of the values will be filled according to today's date. If this still gives problems, put in some echo's for the values of $exp_date and $expiration_date.
Edit
Since this solved the problem, the discrepancy you were seeing was because you were doing the opposite with date('d-m-Y'). You were asking for the current date and the time values are then filled in with the current time. The expiration date in the database is likely set at midnight. With both dates being equal, and it being say 11am now, you are comparing if (00:00:00 > 11:00:00) which fails.
$exp_date = 14/05/2011 // todays date, int
$server_date = server.date() // servers date, int
// check exp_date against server date
if ( $server > $exp_date)
{ echo "Sorry your 'service' has expired"; }
else
{ echo "Welcome 'members_name' to StackOverflow"; }
Try that. However you need the right date format, as server.date() is probably different in PHP.
If problem still persists I would check whether your dates are strings or integers or both. That could possibly be the issue.
Hope that helps.

Your function does not seem to be valid.
function KT_formatDate( $exp_date){
$exp_date = strtotime($exp_date);
$now = time();
if ($now > $exp_date)
return 'expired';
else
return ' Not expired';
}
$response = KT_formatDate($row_issue_whatson1['dateToShow']);
I have a function which checks my database to see if a date exists, if it does exist, i want to display the next date which isnt in the database.
Is this possible?
My function returns 1 if there is a date in the database and 0 if there isnt, im using codeigniter, but not using any built in functions.
Its basically an availability checker, it allows us to input many different dates in the database, so calling my function i use
$availcheck = $ci->availability->check_availability_by_date(date('d/m/Y'));
The i use a if statement to check if the first time it runs it returns a value, this is how i have it
if($availcheck > 0){
// loop through the next dates and run the function again to see if it returns 0
} else {
echo 'available now';
}
I guess i would add 1 to the current date, check that one, then add another 1 and check that and so on.
Im just not sure how.
Cheers,
if i understand you correct , your problem is adding the day ?
if so i would suggest using the epoch or unix time
so convert the date to unix time using mktime than just add 1 day in seconds (24*60*60)
and then convert back to d/m/y format.
you can use the date function.
$date = time(); // get current timestamp
while ($availcheck) // while date IS found in database
{
$availcheck = $ci->availability->check_availability_by_date(date('d/m/Y',$date));
$date = $date + (24*60*60); // add one day
}
$date = $date - (24*60*60); // reduce one day
echo date('d/m/Y',$date); // prints the first date that is not in the DB
This SQL code could work for me.
$today = date("Y-m-d"); //today
$sql = "SELECT date FROM calendar WHERE date>'{$today}' AND date<='2100-12-31' AND date='0000-00-00' LIMIT 1";
Since you can't determine the ending date, 2100 could be for testing.
I'm trying to do a function that will check the php date against what is in the database. If the current date (YYYY-MM-DD HH:MM:SS) is 24 hours after the stored database date, then it will continue, otherwise it won't do anything.. If that makes sense?
Here's how I'm trying to get it to work, but not 100% sure how:
$now = date("Y-m-d H:i:s");
foreach($results as $item) {
if ( /*item date is 24 hours or more earlier than $now*/ ) { /* this is what I'm not sure how to do */
//do something
} else {
//do nothing
};
};
If someone could help me get this working, I'd greatly appreciate it. I just don't know how to compare $item->date with $now and see if $item->date is 24 hours or more behind $now..
You can use strtotime instead of date math. Personally I think it reads much better.
if (strtotime($item->date) <= strtotime('-1 day')) {
// date is more than or equal to 24 hours old
}
foreach($results as $item) {
if (time() >= strtotime($item['date']) + 86400) {
// current time is 86400 (seconds in one day) or more greater than stored time
} else {
//do nothing
};
};
Note that if the stored date isn't in the same timezone as the server you'll need to mess with timezones - see here for starters.
Note that I store dates and times in MySQL as Unix timestamps to avoid some of these problems. I know it's not good database practice, but then PHP stores times as Unix timestamps anyway.
