I am trying to show results of each month.
Im having this for loop:
foreach ($overview as $day) {
$year = date("Y") - 1;
if ($day->user == $info->id) {
$startDate = new DateTime($day->Calendar_startdate);
$endDate = new DateTime($day->Calendar_enddate);
$s = $startDate->format('Y-m-d');
$e = $endDate->format('Y-m-d');
if ($s > $year) {
$workdays = number_of_working_days($s, $e);
$daysleft = $daysleft + $workdays;
} else {
}
}
}
This for loop is also in an if statement which echos the months.
Now I need to let it work for the months January, February etc...
I am able to not show results if in the previous year which works well.
If you want to compare $s with $year just change $year to :
$time = new DateTime('now');
/*** you can use `now` for today
/* or you can change to a fixed date exmp: 2016-01-01
*/
$year = $time->modify('-1 year')->format('Y-m-d');
Than you can compare $s > $year
I fixed by checking each month if it contained for example -01-
DB::table('Calendar')->where('Calendar_startdate', 'like','%' . $monthnumber . '%')->where('user', $info->id)->where('Calendar_type',2)->get();
I have a PHP script which records things based on the day. So it will have a weekly set of inputs you would enter.
I get the data correctly, but when i do $day ++; it will increment the day, going passed the end of the month without ticking the month.
example:
//12/29
//12/30
//12/31
//12/32
//12/33
Where it should look like
//12/29
//12/30
//12/31
//01/01
//01/02
My script is as follows:
$week = date ("Y-m-d", strtotime("last sunday"));
$day = $week;
$run = array(7); //this is actually defined in the data posted to the script, which is pretty much just getting the value of the array index for the query string.
foreach( $run as $key=>$value)
{
$num = $key + 1;
$items[] = "($num, $user, $value, 'run', '$day')";
echo "".$day;
$day ++;
}
Should I be manipulating the datetime differently for day incrementations?
You can use
$day = date("Y-m-d", strtotime($day . " +1 day"));
instead of
$day++;
See live demo in ideone
You refer to $day as a "datetime" but it is just a string - that is what date() returns. So when you do $day++ you are adding 1 to "2015-12-02". PHP will do everything it can to make "2015-12-02" into a number and then add 1 to it, which is not date math. Here is a simple example:
<?php
$name = "Fallenreaper1";
$name++;
echo $name
?>
This will output:
Fallenreaper2
This is how I would do it, using an appropriate data type (DateTime):
<?php
$day = new DateTime('last sunday');
$run = array(7);
foreach ($run as $key => $value) {
$num = $key + 1;
$dayStr = $day->format('Y-m-d');
$items[] = "($num, $user, $value, 'run', '$dayStr')";
echo $dayStr;
$day->modify('+1 day');
}
To increase time you should use strtotime("+1 day");
here is simple example of using it
<?php
$now_time = time();
for($i=1;$i<8;$i++) {
$now_time = strtotime("+1 day", $now_time);
echo date("Y-m-d", $now_time) . "<br>";
}
?>
I have a DATE field on my MySQL table. Let's say the value is 2015-05-05.
I would like to check if the current time is before or after that.
This is my code:
foreach ($row as $row)
{
$ExpDate = strtotime($row['exp_date']);
$Today = strtotime(date("Y-m-d"));
echo $Today . ' - ' . $ExpDate;
if ($Today > $ExpDate)
{
exit('<M>LicenseExpired<M>');
}
}
The problem is that it's not working. The value of exp without strtotime is 2015-05-05. It I add the strtotime, the value becomes an empty string.
How am I able to solve this problem or what would be a good way to compare dates in PHP?
When comparing dates in MySQL there is no reason to take the extra step and use string_to_time(). The below example should work just fine. The format of MySQL DATE is designed in such a way that comparisons of this nature work naturally without any extra steps needed.
foreach ($row as $row)
{
$ExpDate = $row['exp_date'];
$Today = date("Y-m-d");
echo $Today . ' - ' . $ExpDate;
if ($Today > $ExpDate)
{
exit('<M>LicenseExpired<M>');
}
}
try this
foreach ($row as $row)
{
$ExpDate = new DateTime($row['exp_date']);
$Today = new DateTime(date("Y-m-d"));
$interval = $ExpDate->diff($Today);
//echo $interval->format('%R%a days'); <--- to diffenernce by days.
if ($interval > 0)
{
exit('<M>LicenseExpired<M>');
}
}
Does anyone have a PHP snippet to calculate the next business day for a given date?
How does, for example, YYYY-MM-DD need to be converted to find out the next business day?
Example:
For 03.04.2011 (DD-MM-YYYY) the next business day is 04.04.2011.
For 08.04.2011 the next business day is 11.04.2011.
This is the variable containing the date I need to know the next business day for
$cubeTime['time'];
Variable contains: 2011-04-01
result of the snippet should be: 2011-04-04
Next Weekday
This finds the next weekday from a specific date (not including Saturday or Sunday):
echo date('Y-m-d', strtotime('2011-04-05 +1 Weekday'));
You could also do it with a date variable of course:
$myDate = '2011-04-05';
echo date('Y-m-d', strtotime($myDate . ' +1 Weekday'));
UPDATE: Or, if you have access to PHP's DateTime class (very likely):
$date = new DateTime('2018-01-27');
$date->modify('+7 weekday');
echo $date->format('Y-m-d');
Want to Skip Holidays?:
Although the original poster mentioned "I don't need to consider holidays", if you DO happen to want to ignore holidays, just remember - "Holidays" is just an array of whatever dates you don't want to include and differs by country, region, company, person...etc.
Simply put the above code into a function that excludes/loops past the dates you don't want included. Something like this:
$tmpDate = '2015-06-22';
$holidays = ['2015-07-04', '2015-10-31', '2015-12-25'];
$i = 1;
$nextBusinessDay = date('Y-m-d', strtotime($tmpDate . ' +' . $i . ' Weekday'));
while (in_array($nextBusinessDay, $holidays)) {
$i++;
$nextBusinessDay = date('Y-m-d', strtotime($tmpDate . ' +' . $i . ' Weekday'));
}
I'm sure the above code can be simplified or shortened if you want. I tried to write it in an easy-to-understand way.
For UK holidays you can use
https://www.gov.uk/bank-holidays#england-and-wales
The ICS format data is easy to parse. My suggestion is...
# $date must be in YYYY-MM-DD format
# You can pass in either an array of holidays in YYYYMMDD format
# OR a URL for a .ics file containing holidays
# this defaults to the UK government holiday data for England and Wales
function addBusinessDays($date,$numDays=1,$holidays='') {
if ($holidays==='') $holidays = 'https://www.gov.uk/bank-holidays/england-and-wales.ics';
if (!is_array($holidays)) {
$ch = curl_init($holidays);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
$ics = curl_exec($ch);
curl_close($ch);
$ics = explode("\n",$ics);
$ics = preg_grep('/^DTSTART;/',$ics);
$holidays = preg_replace('/^DTSTART;VALUE=DATE:(\\d{4})(\\d{2})(\\d{2}).*/s','$1-$2-$3',$ics);
}
$addDay = 0;
while ($numDays--) {
while (true) {
$addDay++;
$newDate = date('Y-m-d', strtotime("$date +$addDay Days"));
$newDayOfWeek = date('w', strtotime($newDate));
if ( $newDayOfWeek>0 && $newDayOfWeek<6 && !in_array($newDate,$holidays)) break;
}
}
return $newDate;
}
function next_business_day($date) {
$add_day = 0;
do {
$add_day++;
$new_date = date('Y-m-d', strtotime("$date +$add_day Days"));
$new_day_of_week = date('w', strtotime($new_date));
} while($new_day_of_week == 6 || $new_day_of_week == 0);
return $new_date;
}
This function should ignore weekends (6 = Saturday and 0 = Sunday).
This function will calculate the business day in the future or past. Arguments are number of days, forward (1) or backwards(0), and a date. If no date is supplied todays date will be used:
// returned $date Y/m/d
function work_days_from_date($days, $forward, $date=NULL)
{
if(!$date)
{
$date = date('Y-m-d'); // if no date given, use todays date
}
while ($days != 0)
{
$forward == 1 ? $day = strtotime($date.' +1 day') : $day = strtotime($date.' -1 day');
$date = date('Y-m-d',$day);
if( date('N', strtotime($date)) <= 5) // if it's a weekday
{
$days--;
}
}
return $date;
}
What you need to do is:
Convert the provided date into a timestamp.
Use this along with the or w or N formatters for PHP's date command to tell you what day of the week it is.
If it isn't a "business day", you can then increment the timestamp by a day (86400 seconds) and check again until you hit a business day.
N.B.: For this is really work, you'd also need to exclude any bank or public holidays, etc.
I stumbled apon this thread when I was working on a Danish website where I needed to code a "Next day delivery" PHP script.
Here is what I came up with (This will display the name of the next working day in Danish, and the next working + 1 if current time is more than a given limit)
$day["Mon"] = "Mandag";
$day["Tue"] = "Tirsdag";
$day["Wed"] = "Onsdag";
$day["Thu"] = "Torsdag";
$day["Fri"] = "Fredag";
$day["Sat"] = "Lørdag";
$day["Sun"] = "Søndag";
date_default_timezone_set('Europe/Copenhagen');
$date = date('l');
$checkTime = '1400';
$date2 = date(strtotime($date.' +1 Weekday'));
if( date( 'Hi' ) >= $checkTime) {
$date2 = date(strtotime($date.' +2 Weekday'));
}
if (date('l') == 'Saturday'){
$date2 = date(strtotime($date.' +2 Weekday'));
}
if (date('l') == 'Sunday') {
$date2 = date(strtotime($date.' +2 Weekday'));
}
echo '<p>Næste levering: <span>'.$day[date("D", $date2)].'</span></p>';
As you can see in the sample code $checkTime is where I set the time limit which determines if the next day delivery will be +1 working day or +2 working days.
'1400' = 14:00 hours
I know that the if statements can be made more compressed, but I show my code for people to easily understand the way it works.
I hope someone out there can use this little snippet.
Here is the best way to get business days (Mon-Fri) in PHP.
function days()
{
$week=array();
$weekday=["Monday","Tuesday","Wednesday","Thursday","Friday"];
foreach ($weekday as $key => $value)
{
$sort=$value." this week";
$day=date('D', strtotime($sort));
$date=date('d', strtotime($sort));
$year=date('Y-m-d', strtotime($sort));
$weeks['day']= $day;
$weeks['date']= $date;
$weeks['year']= $year;
$week[]=$weeks;
}
return $week;
}
Hope this will help you guys.
Thanks,.
See the example below:
$startDate = new DateTime( '2013-04-01' ); //intialize start date
$endDate = new DateTime( '2013-04-30' ); //initialize end date
$holiday = array('2013-04-11','2013-04-25'); //this is assumed list of holiday
$interval = new DateInterval('P1D'); // set the interval as 1 day
$daterange = new DatePeriod($startDate, $interval ,$endDate);
foreach($daterange as $date){
if($date->format("N") <6 AND !in_array($date->format("Y-m-d"),$holiday))
$result[] = $date->format("Y-m-d");
}
echo "<pre>";print_r($result);

You could do something like this.
/**
* #param string $date
* #param DateTimeZone|null|null $DateTimeZone
* #return \NavigableDate\NavigableDateInterface
*/
function getNextBusinessDay(string $date, ? DateTimeZone $DateTimeZone = null):\NavigableDate\NavigableDateInterface
{
$Date = \NavigableDate\NavigableDateFacade::create($date, $DateTimeZone);
$NextDay = $Date->nextDay();
while(true)
{
$nextDayIndexInTheWeek = (int) $NextDay->format('N');
// check if the day is between Monday and Friday. In DateTime class php, Monday is 1 and Friday is 5
if ($nextDayIndexInTheWeek >= 1 && $nextDayIndexInTheWeek <= 5)
{
break;
}
$NextDay = $NextDay->nextDay();
}
return $NextDay;
}
$date = '2017-02-24';
$NextBussinessDay = getNextBusinessDay($date);
var_dump($NextBussinessDay->format('Y-m-d'));
Output:
string(10) "2017-02-27"
\NavigableDate\NavigableDateFacade::create($date, $DateTimeZone), is provided by php library available at https://packagist.org/packages/ishworkh/navigable-date. You need to first include this library in your project with composer or direct download.
I used below methods in PHP, strtotime() does not work specially in leap year February month.
public static function nextWorkingDay($date, $addDays = 1)
{
if (strlen(trim($date)) <= 10) {
$date = trim($date)." 09:00:00";
}
$date = new DateTime($date);
//Add days
$date->add(new DateInterval('P'.$addDays.'D'));
while ($date->format('N') >= 5)
{
$date->add(new DateInterval('P1D'));
}
return $date->format('Y-m-d H:i:s');
}
This solution for 5 working days (you can change if you required for 6 or 4 days working). if you want to exclude more days like holidays then just check another condition in while loop.
//
while ($date->format('N') >= 5 && !in_array($date->format('Y-m-d'), self::holidayArray()))
I have an events calender that displays events in the order of start date. Everything works great but there is one issue. Events that occur on today's date don't display. I believe that my "if" statement to remove events after they have passed is the issue.
<? while($row = mysql_fetch_assoc($result)) {
$id = $row['id'];
$title = $row['title'];
$text = $row['text'];
$image_url = $row['image_url'];
$start_date = date('F d, Y', strtotime($row['start_date']));
$start_hour = $row['start_hour'];
$start_minute = $row['start_minute'];
$start_am_pm = $row['start_am_pm'];
$end_date = date('F d, Y', strtotime($row['end_date']));
$end_hour = $row['end_hour'];
$end_minute = $row['end_minute'];
$end_am_pm = $row['end_am_pm'];
$tba = $row['tba'];
if(strtotime($row['end_date']) > date('U')) {
?>
First of all, I just want to point out that:
date('U') == time()
So you can use time instead of date.
Now for your problem. If the end_date of your event is set to today, it's probably at the beginning of the day (i.e.: 2010-11-18 00:00:00). That's probably why your conditional does not work, because now is past midnight, the current date/time is greater than the end_date.
Try this:
if (strtotime($row['end_date']) == strtotime('TODAY')) {
// event is today
}
I'm guessing that $row['end_date'] only returns the date not the time. So strtotime($row['end_date']) will = 12:00AM and date('U') will equal return the current time.
So if you ran this at 12:01AM on the date of $row['end_date'], you'd have the comparison of
if("12:00AM today" > "12:01AM today") {
Try
if (strtotime($row['end_date']) >= strtotime(date('Y-m-d'))) {
