How can I get a range of dates in php? - php

$start_date = '2012-01-01';
$end_date = '2012-12-31';
$total_days = round(abs(strtotime($end_date) - strtotime($start_date)) / 86400, 0) + 1;
if ($end_date >= $start_date)
{
for ($day = 0; $day < $total_days; $day++)
{
echo "<br />" . date("Y-m-d", strtotime("{$start_date} + {day} days"));
}
}
Right now that's printing '1969-12-31' over and over. The expected output should be:
2012-01-01
2012-01-02
2012-01-03
...
2012-12-30
2012-12-31

I would use the DatePeriod class (along with DateTime and DateInterval) for this:
$start_date = '2012-01-01';
$end_date = '2012-12-31';
$start = new DateTime($start_date);
$end = new DateTime($end_date);
$interval = new DateInterval('P1D'); // 1 day interval
$period = new DatePeriod($start, $interval, $end);
foreach ($period as $day) {
// Do stuff with each $day...
echo $day->format('Y-m-d'), "\n";
}

You above code will work with one extra character - you missed a $ on this line:
echo "<br />" . date("Y-m-d", strtotime("{$start_date} + {$day} days"));
// ^ This was missing

<?php
$start_date = '2012-01-01';
$end_date = '2012-12-31';
$total_days = round(abs(strtotime($end_date) - strtotime($start_date)) / 86400, 0) + 1;
if ($end_date >= $start_date)
{
for ($day = 0; $day < $total_days; $day++)
{
echo "<br />" . date("Y-m-d", strtotime("{$start_date} + {$day} days"));
// You missed the $ here ^
}
}

PHP Date Selector

I've made the following date selector in PHP for a timetable but when i use it, it starts at the start of PHP time (1970). How do I make it show the current date?
//date selector
$weekStart = 1;
$date = date('Y').'-'. date('m').'-'. date('d');
$timestamp = strtotime($date);
$dayOfWeek = date('N', $timestamp);
echo("<br><br><form action='' name='timetable' method='Post'><div style='position:relative;left:40%;'><h4>Select Week Beginning</h4></div><div style='float:middle;position:relative;left:39%;'><select onchange='submit();' name='date'>");
for ($i = 0; $i <= 10; $i++) {
$startDate = mktime(0,0,0, date('n', $timestamp), date('j', $timestamp) - $dayOfWeek + $weekStart + ( $i * 7), date('Y', $timestamp));
if(date('d-m-Y', $startDate) == $_POST['date']){
$selected = "selected='selected'";
}
else{
$selected = "";
};
echo("<option ".$selected." >". date('d-m-Y', $startDate)."</option>");
}
echo('</select></form></div><br>');
echo("<table style='border:1px solid;'>");
$weekStart = 0;
if(isset($_POST['date'])){
$timestamp = strtotime($_POST['date']);
}else{
$timestamp = strtotime($date);
};
for ($i = 1; $i <= 7; $i++) {
$dayrow = mktime(0,0,0, date('n', $timestamp), date('j', $timestamp) - $dayOfWeek + $weekStart + $i , date('Y', $timestamp));
echo("<td style='text-align:left;width:800px;margin-top:10px;margin-bottom:10px;padding-left:10px;'><h4>".date('D j-m-Y', $dayrow)."</h4></td>");
echo("<td >");

how to display months in descending order starting with current month in php [duplicate]

I'm trying to list all months between two dates.
For example; start date is: 2010-12-02 and last date is: 2012-05-06
I want to list something like this:
2010-12
2011-01
2011-02
2011-03
2011-04
.
.
.
2012-04
2012-05
This is what I have tried and it is not working at all:
$year_min = 2010;
$year_max = 2012;
$month_min = 12;
$month_max = 5;
for($y=$year_min; $y<=$year_max; $y++)
{
for($m=$month_min; $m<=$month_max; $m++)
{
$period[] = $y.$m;
}
}
PHP 5.3
$start = new DateTime('2010-12-02');
$start->modify('first day of this month');
$end = new DateTime('2012-05-06');
$end->modify('first day of next month');
$interval = DateInterval::createFromDateString('1 month');
$period = new DatePeriod($start, $interval, $end);
foreach ($period as $dt) {
echo $dt->format("Y-m") . "<br>\n";
}
See it in action
PHP 5.4 or newer
$start = (new DateTime('2010-12-02'))->modify('first day of this month');
$end = (new DateTime('2012-05-06'))->modify('first day of next month');
$interval = DateInterval::createFromDateString('1 month');
$period = new DatePeriod($start, $interval, $end);
foreach ($period as $dt) {
echo $dt->format("Y-m") . "<br>\n";
}
The part where we modify the start and end dates to the first of the month is important. If we didn't, and the current day higher then the last day in February (i.e. 28 in non-leap years, 29 in leap years) this would skip February.
function getMonthsInRange($startDate, $endDate)
{
$months = array();
while (strtotime($startDate) <= strtotime($endDate)) {
$months[] = array(
'year' => date('Y', strtotime($startDate)),
'month' => date('m', strtotime($startDate)),
);
// Set date to 1 so that new month is returned as the month changes.
$startDate = date('01 M Y', strtotime($startDate . '+ 1 month'));
}
return $months;
}
You must make a difference between two months of the same year and two months of different years.
$year_min = substr($row['contractStart'], 0, 4);
$year_max = substr($row['contractEnd'], 0, 4);
$month_min = substr($row['contractStart'], 5, 2);
$month_min = substr($row['contractEnd'], 5, 2);
$period = array();
try {
if ($year_min > $year_max)
throw new Exception();
else if ($year_min == $year_max)
if ($month_min > $month_max)
throw new Exception();
for ($month = $month_min; $month <= $month_max; $month++) {
$period[] = $month . '-' . $year;
}
else {
for ($month = $month_min; $month <= 12; $month++) {
$period[] = $month . '-' . $year_min;
}
for ($year = $year_min + 1; $year < $year_max; $year++) {
for ($month = $month_min; $month <= $month_max; $month++) {
$period[] = $month . '-' . $year;
}
}
for ($month = 1; $month <= $month_max; $month++) {
$period[] = $month . '-' . $year_max;
}
}
implode("<br />\r\n", $period);
}
catch (Exception $e) {
echo 'Start date occurs after end date.'
}
That's for the hard way. Now there is a quick and easy way that is already given as an answer which I recommend you to choose.
This was my solution since DateTime is not available in my server environment.
$a = "2007-01-01";
$b = "2008-02-15";
$i = date("Ym", strtotime($a));
while($i <= date("Ym", strtotime($b))){
echo $i."\n";
if(substr($i, 4, 2) == "12")
$i = (date("Y", strtotime($i."01")) + 1)."01";
else
$i++;
}

php loop by date of the month

Provided the code stated below, the output are (see below). My question is why after 2009/11/01 it follow's by 2009/11/30 and 2009/12/30 instead of 2009/12/01. From 2009/06/01 ~ 2009/11/01 there is no problem.
output
2009/06/01

2009/09/01
2009/10/01
2009/11/01
