Get whole week date starting from sunday to saturday from given date - php

Question

Hello guys i am working in php and my requirement is to get complete week dates from given date as i need to calculate weekly working hour. And week must be started from sunday to saturday not monday to sunday. I have code which works properly for other days of week except sunday. it means if give any dates from monday to saturday it works properly but if i give sunday's date it give last week's dates. please check my code and advise me for better solution.
$days = array();
$ddate = "2018-01-07";
$date = new DateTime($ddate);
$week = $date->format("W");
$y = date("Y", strtotime($ddate));
echo "Weeknummer: $week"."<br>";
echo "Year: $y"."<br>";
for($day=0; $day<=6; $day++)
{
$days[$day] = date('Y-m-d', strtotime($y."W".$week.$day))."<br>";
}
print_r($days);

Answer 1

Using the DateTime, DateInterval and DatePeriod classes you could do it like this perhaps
function getperiod( $start ){
return new DatePeriod(
new DateTime( $start ),
new DateInterval('P1D'),
new DateTime( date( DATE_COOKIE, strtotime( $start . '+ 7days' ) ) )
);
}
$start='2018-01-07';
$period=getperiod( $start );
foreach( $period as $date ){
echo $date->format('l -> Y-m-d') . '<br />';
}
Which returns
Sunday -> 2018-01-07
Monday -> 2018-01-08
Tuesday -> 2018-01-09
Wednesday -> 2018-01-10
Thursday -> 2018-01-11
Friday -> 2018-01-12
Saturday -> 2018-01-13
Or, by modifying the parameters of the getperiod function you can make that function far more flexible.
function getperiod( $start, $interval='P1D', $days=7 ){
return new DatePeriod(
new DateTime( $start ),
new DateInterval( $interval ),
new DateTime( date( DATE_COOKIE, strtotime( $start . '+ '.$days.' days' ) ) )
);
}
$start='2018-01-07';
$days=array();
$period=getperiod( $start );
foreach( $period as $date ){
$days[]=$date->format('Y-m-d');
}
echo '<pre>',print_r($days,true),'</pre>';
For instance: To find every Sunday for the next year
$period=getperiod( $start,'P7D', 365 );
foreach( $period as $date ){
$days[]=$date->format('Y-m-d');
}
echo '<pre>',print_r($days,true),'</pre>';
To ensure that the calculations begin on a Sunday which has a numeric value of 7
function getperiod( $start, $interval='P1D', $days=7 ){
return new DatePeriod(
new DateTime( $start ),
new DateInterval( $interval ),
new DateTime( date( DATE_COOKIE, strtotime( $start . '+ '.$days.' days' ) ) )
);
}
/* A date from which to begin calculations */
$start='2018-01-01';
/* Array to store output */
$days=array();
/* integer to represent which day of the week to operate upon */
$startday = 7;
/* Output format for resultant dates */
$output='Y-m-d';
/* Calculate initial startdate given above variables */
$start=date( DATE_COOKIE, strtotime( $start . ' + ' . ( $startday - date( 'N', strtotime( $start ) ) ) . ' days' ) );
/* Get the period range */
$period=getperiod( $start );
foreach( $period as $date ){
/* store output in desired format */
$days[]=$date->format( $output );
}
/* do something with data */
echo '<pre>',print_r($days,true),'</pre>';

From source,
Here is the snippet you are looking for,
// set current date
$date = '01/03/2018';
// parse about any English textual datetime description into a Unix timestamp
$ts = strtotime($date);
// calculate the number of days since Monday
$dow = date('w', $ts);
$offset = $dow - 1;
if ($offset < 0) {
$offset = 6;
}
// calculate timestamp for the Monday
$ts = $ts - $offset*86400;
// loop from Monday till Sunday
for ($i = 0; $i < 7; $i++, $ts += 86400){
print date("m/d/Y l", $ts) . "\n";
}
Here is working demo.
If you need normal standard format code,
Here is your snippet,
// set current date
$date = '2018-01-03';
// parse about any English textual datetime description into a Unix timestamp
$ts = strtotime($date);
// calculate the number of days since Monday
$dow = date('w', $ts);
$offset = $dow - 1;
if ($offset < 0) {
$offset = 6;
}
// calculate timestamp for the Monday
$ts = $ts - $offset * 86400;
// loop from Monday till Sunday
for ($i = 0; $i < 7; $i++, $ts += 86400) {
print date("Y-m-d l", $ts) . "\n";
}
Here is working demo.
EDIT
As per your requirement, now week will start from sunday to saturday
<?php
// set current date
$date = '2018-01-03';
// parse about any English textual datetime description into a Unix timestamp
$ts = strtotime($date);
// calculate the number of days since Sunday
$dow = date('w', $ts);
$offset = $dow;
if ($offset < 0) {
$offset = 6;
}
// calculate timestamp for the Sunday
$ts = $ts - $offset * 86400;
// loop from Sunday till Saturday
for ($i = 0; $i < 7; $i++, $ts += 86400) {
print date("Y-m-d l", $ts) . "\n";
}

<?php
$days = array();
$ddate = "2018-01-07";
$y = date("Y", strtotime($ddate));
if(date("l", strtotime($ddate))=='Sunday'){
$ddate = date("Y-m-d ", strtotime($ddate. "+1 day"));
}
$date = new DateTime($ddate);
$week = $date->format("W");
echo "<br/>";
echo "Weeknummer: $week"."<br>";
echo "Year: $y"."<br>";
for($day=0; $day<=6; $day++)
{
$days[$day] = date('Y-m-d', strtotime($y."W".$week.$day))."<br>";
}
print_r($days);
?>

Answer 4

try this:
$days = array();
$ddate = "2018-01-07";
$date = new DateTime($ddate);
$week = $date->format("N")==7?$date->modify("+1 week")->format("W"):$date->format("W");
$y = date("Y", strtotime($ddate));
echo "Weeknummer: $week"."<br>";
echo "Year: $y"."<br>";
for($day=0; $day<=6; $day++)
{
$days[$day] = date('Y-m-d', strtotime($y."W".$week.$day))."<br>";
}
print_r($days);

$dto = new DateTime();
$year = date_create($this->week_date)->format('o');
$week_no = date('W', strtotime($this->week_date));
$dto->setISODate($year, $week_no);
$dto->modify('-1 days');
$ret['sunday'] = $dto->format('Y-m-d');
$dto->modify('+1 days');
$ret['monday'] = $dto->format('Y-m-d');
$dto->modify('+1 days');
$ret['tuesday'] = $dto->format('Y-m-d');
$dto->modify('+1 days');
$ret['wednesday'] = $dto->format('Y-m-d');
$dto->modify('+1 days');
$ret['thursday'] = $dto->format('Y-m-d');
$dto->modify('+1 days');
$ret['friday'] = $dto->format('Y-m-d');
$dto->modify('+1 days');
$ret['saturday'] = $dto->format('Y-m-d');
$dto->modify('+1 days');
$ret['next_sunday'] = $dto->format('Y-m-d');
