How to get the number of days of the current month? - php

I want to check if today is the last day of the month, but I don't really know how.
Can you help?

There is probably a more elegant solution than this but you can just use php's date function:
$maxDays=date('t');
$currentDayOfMonth=date('j');
if($maxDays == $currentDayOfMonth){
//Last day of month
}else{
//Not last day of the month
}

Try to use this:
date('t');

date('t');
or you may use
cal_days_in_month.
see here:
http://php.net/manual/en/function.cal-days-in-month.php

In order to get no. of days in month
you can use either
date('t')
OR
cal_days_in_month(CAL_GREGORIAN, 8, 2003)
And if you wish to check if today is the last day of month
us can use
if(date('d')==date('d',strtotime('last day of month'))){
//your code
}
strtotime offers many great features so check them out first

Use date function:
if (date('t') == date('j'))
{
...
}

Use php's function: cal_days_in_month
More details here
cal_days_in_month(CAL_GREGORIAN, 8, 2003);

$date = new DateTime('last day of this month');
$numDaysOfCurrentMonth = $date->format('d');

this is to find the days in any month:
$days = intval(date('t', strtotime($desiredDate)));

echo date('t'); /// it return last date of current month

And here it is, wrapped up as a function:
function is_last_day_of_month($timestamp = NULL) {
if(is_null($timestamp))
$timestamp = time();
return date('t', $timestamp) == date('j', $timestamp);
}

Using the modern DateTime object class:
$date = new DateTime('last day of this month');

PHP using date() function to get numeric value for Sunday - Saturday

I am trying to get a numeric value (0-6) for the last day of the week in the month however it keeps returning a value of 3 when it in fact should be 4 for the month of 05-2018. Am I going about this in the wrong manner?
$endMonth = date('Y-m-t');
$dayPostition = date('w', $endMonth);
If you want to get the last on current month, you can:
$date = new DateTime("now");
$date->modify('last day of this month');
echo $date->format('w');
Or using a specific date
$date = new DateTime("2018-05-01"); //May 1, 2018
$date->modify('last day of this month');
echo $date->format('w');
The problem is that the second parameter of date() must be a timestamp rather than a string, and date() itself simply returns a string.
As such, you need to explicitly convert the first date() to a timestamp with strtotime():
$testvar = date('Y-m-t');
$lastDay = date('w', strtotime($testvar));
Which can be seen working here.
You are sending a string, not a date... try this
$endMonth = date('Y-m-t');
$dayPostition = date('w', strtotime($endMonth));
If you want to get the last day of month, you can use cal_days_in_month()
This function will return the number of days in the month of year for
the specified calendar."
http://php.net/manual/en/function.cal-days-in-month.
Try this
$getlastday = cal_days_in_month(CAL_GREGORIAN, 05, 2018);
$endMonth = date('2018-05-'.$getlastday);
$dayPostition = date('w', strtotime($endMonth));

PHP Date: get every Friday at specific hour [duplicate]

I would like to find the date stamp of monday, tuesday, wednesday, etc. If that day hasn't come this week yet, I would like the date to be this week, else, next week. Thanks!
See strtotime()
strtotime('next tuesday');
You could probably find out if you have gone past that day by looking at the week number:
$nextTuesday = strtotime('next tuesday');
$weekNo = date('W');
$weekNoNextTuesday = date('W', $nextTuesday);
if ($weekNoNextTuesday != $weekNo) {
//past tuesday
}
I know it's a bit of a late answer but I would like to add my answer for future references.
// Create a new DateTime object
$date = new DateTime();
// Modify the date it contains
$date->modify('next monday');
// Output
echo $date->format('Y-m-d');
The nice thing is that you can also do this with dates other than today:
// Create a new DateTime object
$date = new DateTime('2006-05-20');
// Modify the date it contains
$date->modify('next monday');
// Output
echo $date->format('Y-m-d');
To make the range:
$monday = new DateTime('monday');
// clone start date
$endDate = clone $monday;
// Add 7 days to start date
$endDate->modify('+7 days');
// Increase with an interval of one day
$dateInterval = new DateInterval('P1D');
$dateRange = new DatePeriod($monday, $dateInterval, $endDate);
foreach ($dateRange as $day) {
echo $day->format('Y-m-d')."<br />";
}

The question is tagged "php" so as Tom said, the way to do that would look like this:
date('Y-m-d', strtotime('next tuesday'));
For some reason, strtotime('next friday') display the Friday date of the current week. Try this instead:
//Current date 2020-02-03
$fridayNextWeek = date('Y-m-d', strtotime('friday next week'); //Outputs 2020-02-14
$nextFriday = date('Y-m-d', strtotime('next friday'); //Outputs 2020-02-07
You can use Carbon library.
Example: Next week friday
Carbon::parse("friday next week");
PHP 7.1:
$next_date = new DateTime('next Thursday');
$stamp = $next_date->getTimestamp();
PHP manual getTimestamp()
Sorry, I didn't notice the PHP tag - however someone else might be interested in a VB solution:
Module Module1
Sub Main()
Dim d As Date = Now
Dim nextFriday As Date = DateAdd(DateInterval.Weekday, DayOfWeek.Friday - d.DayOfWeek(), Now)
Console.WriteLine("next friday is " & nextFriday)
Console.ReadLine()
End Sub
End Module
If I understand you correctly, you want the dates of the next 7 days?
You could do the following:
for ($i = 0; $i < 7; $i++)
echo date('d/m/y', time() + 86400 * $i);
Check the documentation for the date function for the format you want it in.
if you want to find Monday then 'dayOfWeek' is 1 if it is Tuesday it will be 2 and so on.
var date=new Date();
getNextDayOfWeek(date, 2);
// this is for finding next tuesday
function getNextDayOfWeek(date, dayOfWeek) {
// Code to check that date and dayOfWeek are valid left as an exercise ;)
var resultDate = new Date(date.getTime());
resultDate.setDate(date.getDate() + (7 + dayOfWeek - date.getDay()) % 7);
return resultDate;
}
Hope this will be helpfull to you, thank you
The PHP documentation for time() shows an example of how you can get a date one week out. You can modify this to instead go into a loop that iterates a maximum of 7 times, get the timestamp each time, get the corresponding date, and from that get the day of the week.

PHP - number of month from date

I'm trying to get the number of a month from a date using this:
$newDate = date("Y-m-d", strtotime('2014-05-04'));
$Month = date('n', $newDate);
echo $Month;
It returns 1 (this is January...) How is this possible? It should return 0.
I used the date format because of that thread:
PHP: date function to get month of the date
I hope somebody can help me.
Thanks in advance
shivan
$Month = date('m', strtotime('2014-05-04'));
you can get the month like this
For datetime operation you should use DateTime class in PHP
$date = new DateTime('2014-05-04');
echo $date->format('n');

how to get the date of last week's (tuesday or any other day) in php?

I think its possible but i cant come up with the right algorithm for it.
What i wanted to do was:
If today is monday feb 2 2009, how would i know the date of last week's tuesday? Using that same code 2 days after, i would find the same date of last week's tuesday with the current date being wednesday, feb 4 2009.
Most of these answers are either too much, or technically incorrect because "last Tuesday" doesn't necessarily mean the Tuesday from last week, it just means the previous Tuesday, which could be within the same week of "now".
The correct answer is:
strtotime('tuesday last week')
I know there is an accepted answer already, but imho it does not meet the second requirement that was asked for. In the above case, strtotime would yield yesterday if used on a wednesday. So, just to be exact you would still need to check for this:
$tuesday = strtotime('last Tuesday');
// check if we need to go back in time one more week
$tuesday = date('W', $tuesday)==date('W') ? $tuesday-7*86400 : $tuesday;
As davil pointed out in his comment, this was kind of a quick-shot of mine. The above calculation will be off by one once a year due to daylight saving time. The good-enough solution would be:
$tuesday = date('W', $tuesday)==date('W') ? $tuesday-7*86400+7200 : $tuesday;
If you need the time to be 0:00h, you'll need some extra effort of course.
PHP actually makes this really easy:
echo strtotime('last Tuesday');
See the strtotime documentation.
Working solution:
$z = date("Y-m-d", strtotime("last Saturday"));
$z = (date('W', strtotime($z)) == date('W')) ? (strtotime($z)-7*86400+7200) : strtotime($z);
print date("Y-m-d", $z);
you forgot strtotime for second argument of date('W', $tuesday)
hmm.
convert $tuesday to timestamp before "$tuesday-7*86400+7200"
mde.
// test: find last date for each day of the week
foreach (array('Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun') as $day) {
print $day . " => " . date('m/d/Y', last_dayofweek($day)) . "\n";
}
function last_dayofweek($day)
{
// return timestamp of last Monday...Friday
// will return today if today is the requested weekday
$day = strtolower(substr($day, 0, 3));
if (strtolower(date('D')) == $day)
return strtotime("today");
else
return strtotime("last {$day}");
}
<?php
$currentDay = date('D');
echo "Today-".$today = date("Y-m-d");
echo "Yesterday-".$yesterday = date("Y-m-d",strtotime('yesterday'));
echo "Same day last week-".$same_day_last_week = date("Y-m-d",strtotime('last '.$currentDay));
?>
Do not use manual calculation, use DateTime object instead. It has proper implementation, takes into account leap years, yeap seconds, etc.
$today = new \DateTime();
$today->modify('tuesday last week');
The modify method modifies the date relative to it's state, so if you set the date to a different date, it calculates it relative to it.
$date = new \DateTime('2020-01-01');
echo $date->format('Y-m-d'); // 2020-01-01
$date->modify('tuesday last week');
echo $date->format('Y-m-d'); // 2019-12-24
