PHP: date function to get month of the current date - php

I want to be able to figure out the month of the current date variable. I'm ex vb.net and the way to do it there is just date.Month. How do I do this in PHP?
Thanks,
Jonesy
I used date_format($date, "m"); //01, 02..12
This is what I wanted, question now is how do I compare this to an int since $monthnumber = 01 just becomes 1

See http://php.net/date
date('m') or date('n') or date('F') ...
Update
m Numeric representation of a month, with leading zeros 01 through 12
n Numeric representation of a month, without leading zeros 1 through 12
F Alphabetic representation of a month January through December
....see the docs link for even more options.

What does your "data variable" look like? If it's like this:
$mydate = "2010-05-12 13:57:01";
You can simply do:
$month = date("m",strtotime($mydate));
For more information, take a look at date and strtotime.
EDIT:
To compare with an int, just do a date_format($date,"n"); which will give you the month without leading zero.
Alternatively, try one of these:
if((int)$month == 1)...
if(abs($month) == 1)...
Or something weird using ltrim, round, floor... but date_format() with "n" would be the best.

$unixtime = strtotime($test);
echo date('m', $unixtime); //month
echo date('d', $unixtime);
echo date('y', $unixtime );

as date_format uses the same format as date ( http://www.php.net/manual/en/function.date.php ) the "Numeric representation of a month, without leading zeros" is a lowercase n .. so
echo date('n'); // "9"

As it's not specified if you mean the system's current date or the date held in a variable, I'll answer for latter with an example.
<?php
$dateAsString = "Wed, 11 Apr 2018 19:00:00 -0500";
// This converts it to a unix timestamp so that the date() function can work with it.
$dateAsUnixTimestamp = strtotime($dateAsString);
// Output it month is various formats according to http://php.net/date
echo date('M',$dateAsUnixTimestamp);
// Will output Apr
echo date('n',$dateAsUnixTimestamp);
// Will output 4
echo date('m',$dateAsUnixTimestamp);
// Will output 04
?>

To compare with an int do this:
<?php
$date = date("m");
$dateToCompareTo = 05;
if (strval($date) == strval($dateToCompareTo)) {
echo "They are the same";
}
?>

How to get a specific date in the current year

Suppose the current year is 2014; then I want get the date 2014-06-30, if the current year is 2015 then I want 2015-06-30
I tried date('Y'); but it is just giving current year.
You can just use:
date("Y-06-30")
Demo : https://eval.in/103028
try:
echo date("Y-06-30");
OUTPUT:
2014-06-30
See date documentation:
http://php.net/manual/en/function.date.php
You can concatenate the rest of your required date to your date() function as follow
echo date('Y') . '-06-30';
//output 2014-06-30
Use this :
date("Y-06-30");
Y will be the your year and rest will same.
Where y is A full numeric representation of a year, 4 digits for more Info : Date()
You need to put like below code:
$d = date('Y');
$data = $d."-06-30";
echo $data;

converting date in php returns different results depending on date format

What seemed to be a fairly standard date conversion is giving me unusual results. I want to get $pay_date into the 'j/d/Y' format, but can only get the correct date if the format is 'Y-m-d'.
Here's my code:
$payment = '2014-09-09';
$pay_date = strtotime("+1 month", strtotime($payment) );
$converter = date('j/d/Y', $pay_date );
echo $converter;
result: 9/09/2014 (should be 10/09/2014)
If I keep these variables, but change $converter to this format:
$converter = date('Y-m-d', $pay_date );
the result is correct - 2014-10-09
I also tried this:
$convert2 = DateTime::createFromFormat('Y-m-d', $pay_date)->format('j/d/Y');
echo $convert2;
result: 9/09/2014
but:
$convert2 = DateTime::createFromFormat('Y-m-d', $pay_date)->format('Y-m-d');
echo $convert2;
gives me the correct result: 2014-10-09
j and d are the same formatting options, they both represent DAYs; from the manual for PHP's date function:
d Day of the month, 2 digits with leading zeros 01 to 31
j Day of the month without leading zeros 1 to 31
Use the format 'm/d/Y'.

Passing a UK date in a URL

I am passing a date in a URL in a UK format as per the following:
http://www.website.com/index.php?from_date=01/04/2013&to_date=12/04/2013
The date range is 1st April 2013 to 12th April 2013.
Then I am using the following PHP to convert it to the YYYY-MM-DD format.
<?php
$rpt_from_date = date("Y-m-d", strtotime($_GET["from_date"]) );
$rpt_to_date = date("Y-m-d", strtotime($_GET["to_date"]) );
echo $rpt_from_date;
echo "</br>";
echo $rpt_to_date;
?>
For some reason this is not working. The above returns the following:
2013-01-04
2013-12-04
It's switching the month and day around. I want it to return:
2013-04-01
2013-04-12
Does anyone have any ideas?
Use DateTime object, to get php understand in which format you passing date to it.
$rpt_from_date = DateTime::createFromFormat('d/m/Y', $_GET["from_date"]);
echo $rpt_from_date->format('Y-m-d');
PHP is reading your time string in the US format (MM/DD/YYYY) because you are using slashes. You could use dashes to give the time: index.php?from_date=01-04-2013&to_date=12-04-2013, or convert it yourself:
$uktime = implode("-", explode("/", $_GET['from_date']));
I will provide the solution but it is not using the date function:
$arr = explode("/",$_GET["from_date"]);
$from_date = $arr[2]."-".$arr[1]."-"$arr[0];
Second solution is as following:
$from_date = implode(array_reverse(explode("/",$_GET["from_date"])));

Date format form Jan 30 to 2011-01-30

I have the following date format in a xml sheet:
Jan 30
and I want to display as:
2011-01-30
2011 being the current year
Can someone help me with that?
strtotime will use the current year if none is specified, so this would work
$t=strtotime("Jan 30");
echo strftime("%Y-%m-%d", $t);
strtotime + date gives you:
echo date("Y-m-d", strtotime('30 Jan')); //echoes '2011-01-30'
care to post the xml?
in anycase, take the string
$x = "Jan 30"
add 2011
$x = $x . ' ' . date('Y');
convert it to date time and format it
$y = date_format('Y-m-d', strtotime($x));
echo $y;`
strtotime is your key here, it converts most any date format into seconds since the epoch, then all you need do is use the date_format function

Can't get previous month from DateTime in PHP- Is this a (pretty big) bug?

I need to create functions in PHP that let me step up/down given datetime units. Specifically, I need to be able to move to the next/previous month from the current one.
I thought I could do this using DateTime::add/sub(P1M). However, when trying to get the previous month, it messes up if the date value = 31- looks like it's actually trying to count back 30 days instead of decrementing the month value!:
$prevMonth = new DateTime('2010-12-31');
Try to decrement the month:
$prevMonth->sub(new DateInterval('P1M')); // = '2010-12-01'
$prevMonth->add(DateInterval::createFromDateString('-1 month')); // = '2010-12-01'
$prevMonth->sub(DateInterval::createFromDateString('+1 month')); // = '2010-12-01'
$prevMonth->add(DateInterval::createFromDateString('previous month')); // = '2010-12-01'
This certainly seems like the wrong behavior. Anyone have any insight?
Thanks-
NOTE: PHP version 5.3.3
(Credit actually belongs to Alex for pointing this out in the comments)
The problem is not a PHP one but a GNU one, as outlined here:
Relative items in date strings
The key here is differentiating between the concept of 'this date last month', which, because months are 'fuzzy units' with different numbers of dates, is impossible to define for a date like Dec 31 (because Nov 31 doesn't exist), and the concept of 'last month, irrespective of date'.
If all we're interested in is the previous month, the only way to gaurantee a proper DateInterval calculation is to reset the date value to the 1st, or some other number that every month will have.
What really strikes me is how undocumented this issue is, in PHP and elsewhere- considering how much date-dependent software it's probably affecting.
Here's a safe way to handle it:
/*
Handles month/year increment calculations in a safe way,
avoiding the pitfall of 'fuzzy' month units.
Returns a DateTime object with incremented month/year values, and a date value == 1.
*/
function incrementDate($startDate, $monthIncrement = 0, $yearIncrement = 0) {
$startingTimeStamp = $startDate->getTimestamp();
// Get the month value of the given date:
$monthString = date('Y-m', $startingTimeStamp);
// Create a date string corresponding to the 1st of the give month,
// making it safe for monthly/yearly calculations:
$safeDateString = "first day of $monthString";
// Increment date by given month/year increments:
$incrementedDateString = "$safeDateString $monthIncrement month $yearIncrement year";
$newTimeStamp = strtotime($incrementedDateString);
$newDate = DateTime::createFromFormat('U', $newTimeStamp);
return $newDate;
}
Easiest way to achieve this in my opinion is using mktime.
Like this:
$date = mktime(0,0,0,date('m')-1,date('d'),date('Y'));
echo date('d-m-Y', $date);

p.s mktime documentation can be found here: http://nl2.php.net/mktime
You could go old school on it and just use the date and strtotime functions.
$date = '2010-12-31';
$monthOnly = date('Y-m', strtotime($date));
$previousMonth = date('Y-m-d', strtotime($monthOnly . ' -1 month'));
(This maybe should be a comment but it's to long for one)
Here is how it works on windows 7 Apache 2.2.15 with PHP 5.3.3:
<?php $dt = new DateTime('2010-12-31');
$dt->sub(new DateInterval('P1M'));
print $dt->format('Y-m-d').'<br>';
$dt->add(DateInterval::createFromDateString('-1 month'));
print $dt->format('Y-m-d').'<br>';
$dt->sub(DateInterval::createFromDateString('+1 month'));
print $dt->format('Y-m-d').'<br>';
$dt->add(DateInterval::createFromDateString('previous month'));
print $dt->format('Y-m-d').'<br>'; ?>
2010-12-01
2010-11-01
2010-10-01
2010-09-01
So this does seem to confirm it's related to the GNU above.
Note: IMO the code below works as expected.
$dt->sub(new DateInterval('P1M'));
Current month: 12
Last month: 11
Number of Days in 12th month: 31
Number of Days in 11th month: 30
Dec 31st - 31 days = Nov 31st
Nov 31st = Nov 1 + 31 Days = 1st of Dec (30+1)
