Usages of PHP date, strtotime and mktime functions
To customize date and time PHP provides us some important functions such date, strtotime and mktime. In this post i will demonstrate some usages for these
functions.
Example 1:
Get year start and end date for the current year we can use
$yearStart = date("Y-m-d", strtotime('this year January 1st'));
$yearEnd = date("Y-m-d", strtotime("this year December 31st"));
Example 2:
Get month start and end date for the current month
$monthStart = date("Y-m-d", strtotime('first day of this month'));
$monthEnd = date("Y-m-d", strtotime("last day of this month"));
Example 3:
Get previous month start and end date
$lastMonthStart = date("Y-m-d", strtotime('first day of last month'));
$lastMonthEnd = date("Y-m-d", strtotime("last day of last month"));
Example 4:
Get week start and end date
$weekStart = date("Y-m-d", strtotime('monday this week'));
$weekEnd = date("Y-m-d", strtotime("sunday this week"));
Example 5:
get the first and last days of a given month
$query_date = '2010-02-04';
echo date('Y-m-01', strtotime($query_date));
echo date('Y-m-t', strtotime($query_date));
Example 6:
Displaying the list of months using mktime for the year
for ($m=1; $m<=12; $m++) {
$month = date('F', mktime(0,0,0,$m, 1, date('Y')));
echo $month;
}
Example 7:
run foreach loop between 2 given dates
$begin = new DateTime( '2010-05-01' );
$end = new DateTime( '2010-05-10' );
$interval = DateInterval::createFromDateString('1 day');
$period = new DatePeriod($begin, $interval, $end);
foreach ($period as $dt){
echo $dt->format( "l Y-m-d H:i:s\n" );
}
