How to verify if specific date is monday in php - php

i have a script that generates week days with a next and preview. It workes perfect but i also added a callendar that is autosubmiting on change. the problem i have with it is that when i select a day and that day is monday is still goes me to last week. What i need is to verify if the selected day is monday and give $monday that date instead giving it the last week monday. Here is my script:
$date = strtotime(date($_GET['date']));
$monday = "";
if (isset($_GET['n_startdate'])) {
$date = $_GET['n_startdate'];
$lastweek = strtotime("next week", $date);
$monday = strtotime("last Monday", $lastweek);
} else if ( isset($_GET['p_startdate'])) {
$date = $_GET['p_startdate'];
$lastweek = strtotime("-7 days", $date);
$monday = strtotime("last Monday", $date);
} else if($date!='' ){
$monday = strtotime("last Monday", $date);
} else {
$date = strtotime(date('Y-m-d H:i:s'));
$monday = strtotime("last Monday", $date);
}
edit: i don't get why i got -1 to my question :(

If you want to find out if a given date is a day of the week, use the "D" flag for the date function.
if(date('D', $unixTimestamp) === 'Mon') {
//Do what you want here
}
You can find more details on the PHP manual page for the date function here - http://php.net/manual/en/function.date.php

How to get Last sunday date in Bootstrap Datepicker?

I am using bootstrap Datepicker and I want to set the date for current/last Sunday.The code below is showing the content form $date to $date1.
if (!isset($_POST['new-date'])){
$date = date('Y-m-d H:i:s');// I want to set last/current sunday
date here.
$date1 = date("Y-m-d H:i:s", strtotime("$date +6 day"));
$d = explode(" ",$date);
$d1 = explode(" ",$date1);
} else {
$d[0] = $_POST['new-date'];
$d1[0] = date("Y-m-d", strtotime("$d[0] +6 day"));
}
$d[0] = $_POST['new-date'];
The ['new-date'] may be any day/date from the calendar but It should select the last Sunday of that particular week.
Your code seems to be written in PHP, rather than JavaScript, so I'm not sure how relevant the question title or tags are.
// Check if the day of the week is a Sunday. If yes, use today's date. If no, use last Sunday's date
$timestamp = date('N') == 7 ? strtotime('today') : strtotime('last sunday');
$date = date('Y-m-d H:i:s', $timestamp);
die($date);
Edit
You asked in the comments how you can find last Sunday for any given date.
$timestamp = strtotime($_POST['date'] ?? 'today');
$sunday = (date('N', $timestamp) == 7) ? $timestamp : strtotime('last sunday', $timestamp);
$date = date('Y-m-d H:i:s', $sunday);
die($date);

How to get week start date Sunday and week end date Saturday in php

How to get week start date Sunday and week end date Saturday in php.
I try my self below to code am getting Week Start Date as Monday Week End Date as Sunday.
$cdate = date("Y-m-d");
$week = date('W', strtotime($cdate));
$year = date('Y', strtotime($cdate));
$firstdayofweek = date("Y-m-d", strtotime("{$year}-W{$week}+1"));
$lastdayofweek = date("Y-m-d", strtotime("{$year}-W{$week}-7"));
Thanks,

Here is a solution using DateTime, which is a little bit nicer to work with than date and strtotime :) :
$today = new \DateTime();
$currentWeekDay = $today->format('w'); // Weekday as a number (0 = Sunday, 6 = Saturday)
$firstdayofweek = clone $today;
$lastdayofweek = clone $today;
if ($currentWeekDay !== '0') {
$firstdayofweek->modify('last sunday');
}
if ($currentWeekDay !== '6') {
$lastdayofweek->modify('next saturday');
}
echo $firstdayofweek->format('Y-m-d').PHP_EOL;
echo $lastdayofweek->format('Y-m-d').PHP_EOL;
Change your local configuration :
setlocale('LC_TIME', 'fr_FR.utf8');
Change 'fr_FR.utf8' by your local.
I changed my code like below. This code is correct ? but it's worked for me.
$cdate = date("Y-m-d");
$week = date('W', strtotime($cdate));
$year = date('Y', strtotime($cdate));
echo "<br>".$firstdayofweek = date("Y-m-d", strtotime("{$year}-W{$week}-0"));
echo "<br>".$lastdayofweek = date("Y-m-d", strtotime("{$year}-W{$week}-6"));

how can I get last week' date range in php?

how can I get last week' date range in php ?
see my codes bellow:
<?php
function get_last_week_dates(){
// how can i get the date range last week ?
// ex: today is 2014-2-8
// the week date range of last week should be '2014-1-26 ~ 2014-2-1'
}
?>
You can use strtotime()
$previous_week = strtotime("-1 week +1 day");
$start_week = strtotime("last sunday midnight",$previous_week);
$end_week = strtotime("next saturday",$start_week);
$start_week = date("Y-m-d",$start_week);
$end_week = date("Y-m-d",$end_week);
echo $start_week.' '.$end_week ;
UPDATE
Changed the code to handle sunday. If the current day is sunday then - 1 week will be previous sunday and again getting previous sunday for that will go the one week back.
$previous_week = strtotime("-1 week +1 day");
In addition if we need to find the current week and next week date
range we can do as
Current week -
$d = strtotime("today");
$start_week = strtotime("last sunday midnight",$d);
$end_week = strtotime("next saturday",$d);
$start = date("Y-m-d",$start_week);
$end = date("Y-m-d",$end_week);
Next Week -
$d = strtotime("+1 week -1 day");
$start_week = strtotime("last sunday midnight",$d);
$end_week = strtotime("next saturday",$d);
$start = date("Y-m-d",$start_week);
$end = date("Y-m-d",$end_week);
Simply use
date("m/d/Y", strtotime("last week monday"));
date("m/d/Y", strtotime("last week sunday"));
It will give the date of Last week's Monday and Sunday.
you need you use strtotime function for this
<center>
<?php
function get_last_week_dates()
{
// how can i get the date range last week ?
// ex: today is 2014-2-8
// the week date range of last week should be '2014-1-26 ~ 2014-2-1'
$startdate = "last monday";
if (date('N') !== '1')
{
// it's not Monday today
$startdate .= " last week";
}
echo "<br />";
$day = strtotime($startdate);
echo date('r', $day);
echo "<br />";
$sunday = strtotime('next monday', $day) - 1;
echo date('r', $sunday);
}
get_last_week_dates();
?>
</center>
Well just for the fun of trying to solve this:
date_default_timezone_set('UTC');
$firstDayOfLastWeek = mktime(0,0,0,date("m"),date("d")-date("w")-7);
$lastDayOfLastWeek = mktime(0,0,0,date("m"),date("d")-date("w")-1);
echo("Last week began on: ".date("d.m.Y",$firstDayOfLastWeek));
echo("<br>");
echo("Last week ended on: ".date("d.m.Y",$lastDayOfLastWeek));
This should do the trick
$startWeek = date('Y-m-d',strtotime("Sunday Last Week"));
$endWeek = date('Y-m-d',strtotime("Sunday This Week"));
this would not work if ran on a Monday. It would get last Sunday (the day before) to the next Sunday. So using Abhik Chakraborty's method with the above:
$startTime = strtotime("last sunday midnight",$previous_week);
$endTime = strtotime("next sunday midnight",$startTime);
$startDate = date('Y-m-d 00:00:00',$startTime);
$endDate = date('Y-m-d 23:59:59',$endTime);
This will now give
start = 2014-08-10 00:00:00
endDate = 2014-08-17 23:59:59
I know this is old but here's a much more succinct way of doing it:
$startDate = date("m/d/y", strtotime(date("w") ? "2 sundays ago" : "last sunday"));
$endDate = date("m/d/y", strtotime("last saturday"));
echo $startDate . " - " . $endDate
This one will produce the proper result and handles the Monday issue
<?php
$monday = strtotime("last monday");
$monday = date('W', $monday)==date('W') ? $monday-7*86400 : $monday;
$sunday = strtotime(date("Y-m-d",$monday)." +6 days");
$this_week_sd = date("Y-m-d",$monday);
$this_week_ed = date("Y-m-d",$sunday);
echo "Last week range from $this_week_sd to $this_week_ed ";
?>
Most of those other solutions offered were off by one day.
If you want Sunday to Saturday for last week, this is the way to do it.
$start = date("Y-m-d",strtotime("last sunday",strtotime("-1 week")));
$end = date("Y-m-d",strtotime("saturday",strtotime("-1 week")));
echo $start. " to ".$end;
Carbon
$startOfTheWeek = Carbon::now()->subWeek(1)->startOfWeek();
$endOfTheWeek = Carbon::now()->subWeek(1)->endOfWeek();
From a specific date
$startOfTheWeek = Carbon::parse('2020-03-02')->subWeek(1)->startOfWeek();
$endOfTheWeek = Carbon::parse('2020-03-02')->subWeek(1)->endOfWeek();
Considering the week starts at Monday and ends at Sunday.
You can do this way.
First get the current timestamp and subtract the no.of days you want.
$curTime = time();
echo date("Y-m-d",$curTime);
echo "<br />";
echo date("Y-m-d",($curTime-(60*60*24*7)));
$lastWeekStartTime = strtotime("last sunday",strtotime("-1 week"));
$lastWeekEndTime = strtotime("this sunday",strtotime("-1 week"));
$lastWeekStart = date("Y-m-d",$lastWeekStartTime);
$lastWeekEnd = date("Y-m-d",$lastWeekEndTime);
In order to find the last week start date and end date you can follow up this code for doing it so.
It works on all intervals to find the date interval.
$Current = Date('N');
$DaysToSunday = 7 - $Current;
$DaysFromMonday = $Current - 1;
$Sunday = Date('d/m/y', strtotime("+ {$DaysToSunday} Days"));
$Monday = Date('d/m/y', strtotime("- {$DaysFromMonday} Days"));
If so you need to change it with the datatime() you can perform this function.
$date = new DateTime();
$weekday = $date->format('w');
$diff = 7 + ($weekday == 0 ? 6 : $weekday - 1); // Monday=0, Sunday=6
$date->modify("-$diff day");
echo $date->format('Y-m-d') . ' - ';
$date->modify('+6 day');
echo $date->format('Y-m-d');
Using Functions:
If you want to find the last week range with the help of the functions you can preform like this.
Function:
// returns last week's range
function last_week_range($date) {
$ts = strtotime("$date - 7 days");
$start = (date('w', $ts) == 0) ? $ts : strtotime('last sunday', $ts);
return array(
date('Y-m-d', $start),
date('Y-m-d', strtotime('next saturday', $start))
);
}
Usage:
$today=date();
print_r(last_week_range($today));
All the above functions that has been given will return the last week range irrespective of the start day of the week..

PHP - how to use $timestamp to check if today is Monday or 1st of the month?

I have been looking through examples online, and I am finding them a bit cryptic or overkill.
What I need to do is something like this:
$timestamp = time();
and then find out if the day is a Monday or a fist of the month?
I am sure it is possible, I am just not sure how to do that.
Actually, you don't need timestamp variable because:
Exerpt from date function of php.net:
Returns a string formatted according to the given format string using
the given integer timestamp or the current time if no timestamp is
given. In other words, timestamp is optional and defaults to the value
of time().
if(date('j', $timestamp) === '1')
echo "It is the first day of the month today\n";
if(date('D', $timestamp) === 'Mon')
echo "It is Monday today\n";
This should solve it:
$day = date('D');
$date = date('d')
if($day == Mon){
//Code for monday
}
if($date == 01){
//code for 1st fo the month
}
else{
//not the first, no money for you =/
}
This will grab.. Monday from mysql
$monday = 1; //tuesday= 2.. sunday = 7
AND $monday = (date_format(from_unixtime(your_date_column),'%w'))
OR days..
$day = 1; ///1st in month
AND $day = (date_format(from_unixtime(your_date_column),'%d'))
JUST TO KNOW
$date = date("d"); //1st?
$dayinweek = date("w"); //monday? //as a number in a week what you need more then just "Monday" I guess..
You can use: strtotime
$firstdaymonth = strtotime('first day this month');
Because $date can monday or sunday. Should be check it
public function getWeek($date){
$date_stamp = strtotime(date('Y-m-d', strtotime($date)));
//check date is sunday or monday
$stamp = date('l', $date_stamp);
if($stamp == 'Mon'){
$week_start = $date;
}else{
$week_start = date('Y-m-d', strtotime('Last Monday', $date_stamp));
}
if($stamp == 'Sunday'){
$week_end = $date;
}else{
$week_end = date('Y-m-d', strtotime('Next Sunday', $date_stamp));
}
return array($week_start, $week_end);
}
Since PHP >= 5.1 it is possible to use date('N'), which returns an ISO-8601 numeric representation of the day of the week, where 1 is Monday and 7 is Sunday.
So you can do
if(date('N', $timestamp) === '1' || date('j', $timestamp) === '1')) {
echo "Today it is Monday OR the first of the month";
}
