date
Returns a string formatted according to the given format string using the given integer timestamp (Unix timestamp) or the current time if no timestamp is given. In other words, timestamp is optional and defaults to the value of time() .
Unix timestamps do not handle timezones. Use the DateTimeImmutable class, and its DateTimeInterface::format() formatting method to format date/time information with a timezone attached.
Parameters
Note: date() will always generate 000000 as microseconds since it takes an int parameter, whereas DateTime::format() does support microseconds if DateTime was created with microseconds.
The optional timestamp parameter is an int Unix timestamp that defaults to the current local time if timestamp is omitted or null . In other words, it defaults to the value of time() .
Return Values
Returns a formatted date string.
Errors/Exceptions
Every call to a date/time function will generate a E_WARNING if the time zone is not valid. See also date_default_timezone_set()

Examples
Example #1 date() examples
// set the default timezone to use.
date_default_timezone_set ( ‘UTC’ );
?php
// Prints something like: Monday
echo date ( «l» );
// Prints something like: Monday 8th of August 2005 03:12:46 PM
echo date ( ‘l jS \of F Y h:i:s A’ );
// Prints: July 1, 2000 is on a Saturday
echo «July 1, 2000 is on a » . date ( «l» , mktime ( 0 , 0 , 0 , 7 , 1 , 2000 ));
/* use the constants in the format parameter */
// prints something like: Wed, 25 Sep 2013 15:28:57 -0700
echo date ( DATE_RFC2822 );
// prints something like: 2000-07-01T00:00:00+00:00
echo date ( DATE_ATOM , mktime ( 0 , 0 , 0 , 7 , 1 , 2000 ));

You can prevent a recognized character in the format string from being expanded by escaping it with a preceding backslash. If the character with a backslash is already a special sequence, you may need to also escape the backslash.
Example #2 Escaping characters in date()
It is possible to use date() and mktime() together to find dates in the future or the past.
Example #3 date() and mktime() example
$tomorrow = mktime ( 0 , 0 , 0 , date ( «m» ) , date ( «d» )+ 1 , date ( «Y» ));
$lastmonth = mktime ( 0 , 0 , 0 , date ( «m» )- 1 , date ( «d» ), date ( «Y» ));
$nextyear = mktime ( 0 , 0 , 0 , date ( «m» ), date ( «d» ), date ( «Y» )+ 1 );
?>?php
Note:
This can be more reliable than simply adding or subtracting the number of seconds in a day or month to a timestamp because of daylight saving time.
Some examples of date() formatting. Note that you should escape any other characters, as any which currently have a special meaning will produce undesirable results, and other characters may be assigned meaning in future PHP versions. When escaping, be sure to use single quotes to prevent characters like \n from becoming newlines.
Example #4 date() Formatting
// Assuming today is March 10th, 2001, 5:16:18 pm, and that we are in the
// Mountain Standard Time (MST) Time Zone
?php
$today = date ( «F j, Y, g:i a» ); // March 10, 2001, 5:16 pm
$today = date ( «m.d.y» ); // 03.10.01
$today = date ( «j, n, Y» ); // 10, 3, 2001
$today = date ( «Ymd» ); // 20010310
$today = date ( ‘h-i-s, j-m-y, it is w Day’ ); // 05-16-18, 10-03-01, 1631 1618 6 Satpm01
$today = date ( ‘\i\t \i\s \t\h\e jS \d\a\y.’ ); // it is the 10th day.
$today = date ( «D M j G:i:s T Y» ); // Sat Mar 10 17:16:18 MST 2001
$today = date ( ‘H:m:s \m \i\s\ \m\o\n\t\h’ ); // 17:03:18 m is month
$today = date ( «H:i:s» ); // 17:16:18
$today = date ( «Y-m-d H:i:s» ); // 2001-03-10 17:16:18 (the MySQL DATETIME format)
?>
To format dates in other languages, IntlDateFormatter::format() can be used instead of date() .
Notes
Note:
To generate a timestamp from a string representation of the date, you may be able to use strtotime() . Additionally, some databases have functions to convert their date formats into timestamps (such as MySQL’s » UNIX_TIMESTAMP function).
Timestamp of the start of the request is available in $_SERVER[‘REQUEST_TIME’] .

Php check if this month php
Example: In this case the date is in the month december (like my variable) This function from the PHP manual seems to do the trick function was copied from this answer or php.net Question: I have a simple question about show data if month has passed.
Check if date is certain month
I have two dates, one from an API which I can’t change. And one I create myself which is a month. I want to check if the date i get from the api is in the same month i provide.
$month = '12'; //december $date = '2019-12-09 13:34:23' // date from api (cant change the way it comes in)
In this case the date is in the month december (like my variable) so i would like to built something that returns true if this is the case, but sadly i dont know where to start
$dateValue = strtotime($q); $yr = date("Y", $dateValue); $mon = date("m", $dateValue); $date = date("d", $dateValue);
you can do something like this then you can match with if condition.
You could try like this perhaps:
$month = '12'; $date = '2019-12-09 13:34:23'; if( date('M',strtotime($date)) == date('M', mktime( 0, 0, 0, $month, 1, date('Y') ) ) )echo 'same';
$date = date_parse($date); if ($month == $date['month'])
if( date_create($date)->format('m') == $month )
PHP: How to know if a date is in the current month?, Sorted by: 9. You can do it all on one line. Basically convert the date in question to a PHP time, and get the month. date (‘m’,strtotime (‘2018-06-30’ )) == date (‘m’); Using the date () function, if you pass in only the format, it’ll assume the current date/time. You can pass in a second optional variable of a time () object … Code sample$date = «2018-07-31»;if(date(«m», strtotime($date)) == date(«m»)) <>else <>Feedback
How do I check that the given string is a valid month or not?
I’m making a function to check the month is valid or not. For eg.
checkMonth("Feb") => true checkMonth("Mar") => true checkMonth(02) => true checkMonth(2) => true
checkMonth("X") => false checkMonth("XYZ") => false
There is no issue in the numeric form 2 or 02. But if I’m passing argument like «X» or «XYZ» its not working and returns true.
which is returning true because the value of date(‘n’, strtotime(«XYZ»)) is 3 which is a valid month .
$mon=date_format(date_create("XYZ"),"n");
But it has the same affect.
$month = 'XYZ'; $x = DateTime::createFromFormat('M', $month); if (!$x) < die($month . ' is not a valid month'); >echo $month, 'is month number ', $x->format('n'), PHP_EOL;
(only works with English language names for months)
You can create your own function and setup an array that holds the 1,2,3,4 and 01,02,03 and jan,feb,march and then in your function you check if string exists in the array, then return true 🙂
EDIT: if you want to make it cooler you can make a preg_match. but is a little bit trickier 😛
EDIT 2: you can use checkdate: http://php.net/manual/en/function.checkdate.php
Gives me null value and Prints true!
You could have a function like
Please note that my php is a bit hazy so the syntax might be wrong.
This function from the PHP manual seems to do the trick

Show data if month has passed
I have a simple question about show data if month has passed. What I can do with PHP date?
For example, if May has passed then the data will show. I want if just the month has passed.
if (date('n') > date('n', strtotime('Month_Name'))) < //do work >
For this to work, $month needs to be a numerical month, eg 1 for January etc.
$now = new DateTime(); if($month < (int)$now->format('m'))
or (slightly more readable?):-
$currMonth = (int)(new DateTime())->format('m'); if($month
There is a better option for you. For example if you wan’t to see if July of the current year has passed:-
$july = (new \DateTime('last day of July'))->setTime(23, 59, 59); $now = new \DateTime(); if($now > $july) < //Do something >
Be arware that your probably have to add a year if $month = ‘december’; .
Php check date if month is equal to something, So i fetched the date into MSSQL’s datetime type field. E.g 2014-01-23 06:54:49.647. I need a simple way to determine if the datetime corresponds a specific month in a condition in PHP
