Hi,
I want to find All no of week in any month.
And first and last date of that week.
Assume Month is Jan 2011
date in Y-m-d
1st week -> Start date=2011-01-01 End date=2011-01-01
2nd week -> Start date=2011-01-02 End date=2011-01-08
3rd week -> Start date=2011-01-09 End date=2011-01-15
4th week -> Start date=2011-01-16 End date=2011-01-22
5th week -> Start date=2011-01-23 End date=2011-01-29
6th week -> Start date=2011-01-30 End date=2011-01-31
How to Find all these?
Jump to PostWhat you want to use, myql query , php code or combination of both?
Jump to PostWell, it depends. Do you want the first day of the week to always be the first day of the month?

<form method="post">
M: <input name="m" value="6" />
Y: <input name="y" value="2011" />
<input type="submit" value="go" />
</form>You can try that. I've probably over-egged the calculations, but it seems to work. You could easily add functionality for date input formats (e.g. '6/2011' or 'Jun 2011'). You could use strtotime() or similar for this.
Dont know if this is what you are looking for, I see you have thumbnail of a calender in your question, but I programmed a small calendar one time and you can use it if you like:
function determine_next_months(&$month, &$year){
if($month == 1){
$prev_month = 12;
$next_month = 2;
$prev_year = $year - 1;
$next_year = $year;
}
else if($month == 12){
$prev_month = 11;
$next_month = 1;
$prev_year = $year;
$next_year = $year + 1;
}
else{
$prev_month = $month - 1;
$next_month = $month + 1;
$prev_year = $year;
$next_year = $year;
}
?>
<tr height="30">
<td colspan="3" align="right"><a href="tester.php?month=<?php echo $prev_month."&year=".$prev_year; ?>"><img src="images/Knob Left.png" /></a></td>
<td></td>
<td colspan="3" align="left"><a href="tester.php?month=<?php echo $next_month."&year=".$next_year; ?>"><img src="images/Knob Forward.png" /></a></td>
</tr>
<?php
}
function make_calendar(&$current_month, &$current_year, &$current_month_text, &$current_day = "", $my_array){
//First initialize counters for us in the for calender for loop.
$count_col = 0;
$count_days = 1;
//determine the first weekday of the month(to know how many empty columns to print and then when to start printing out the days)
$first_weekday = date('w', mktime(0, 0, 0, $current_month, 1, $current_year));
//Here we determine the last day of the month(to know when to stop printing out days and how many empty columns after that.).
//First I put the limit to 31, then decrement the counter until I hit the right day, then I break out of the loop and $i is then the last day
$limit = 31;
for($i = $limit; $i > 28; $i--){
if(checkdate($current_month, $i, $current_year)){
break;
}
}
//reset the limit variable to what is stored in $i, since I plan to use $i to count in next loop.
$limit = $i;

</html>I changed the code a bit before I posted it here, so there are some broken links, like some links direct to events.php and others to tester.php. Obviously the css style sheet is missing and I threw the database connection out that fetches event dates and just put instead 2, 7, 8.
If there are sessions on your page, then you would want to strip the get variables of all tags
But this calendar always starts on the current month, has previous and next month links to fetch other months, different styling for current date, different styling and link on special dates(with events) and no styles for empty dates.
Possibly it is something you can use.
Notice on line 35 you can see in one line how to get the weekday of the first day of the month. And online 38-43 you can see how to determine last day of the month(although there is probably a better way to do this than 5 lines of code).
Hi ardav,
I tried this code. On some conditions it fails like 10 2010 (i.e.October 2010)
It gives output
1st week -> Start date=2010-10-01 End date=2010-10-02
2nd week -> Start date=2010-10-03 End date=2010-10-09
3rd week -> Start date=2010-10-10 End date=2010-10-16
4th week -> Start date=2010-10-17 End date=2010-10-23
5th week -> Start date=2010-10-24 End date=2010-10-31
<?php
$textdt="01 june 2011";
$dt= strtotime( $textdt);
$currdt=$dt;
$nextmonth=strtotime($textdt."+1 month");
$i=0;
do
{
$weekday= date("w",$currdt);
$nextday=7-$weekday;
$endday=abs($weekday-6);
$startarr[$i]=$currdt;
$endarr[$i]=strtotime(date("Y-m-d",$currdt)."+$endday day");
$currdt=strtotime(date("Y-m-d",$endarr[$i])."+1 day");
echo "Week ".($i+1). "-> start date = ". date("Y-m-d",$startarr[$i])." end date = ". date("Y-m-d",$endarr[$i])."<br>";
$i++;
}while($endarr[$i-1]<$nextmonth);
?>Brilliant U! Nice and simple.
However, the last end date is a bit off.
Last date is show as expected by AAMIT.
Your code (which I love BTW) gives:
Week 1-> start date = 2011-06-01 end date = 2011-06-04
Week 2-> start date = 2011-06-05 end date = 2011-06-11
Week 3-> start date = 2011-06-12 end date = 2011-06-18
Week 4-> start date = 2011-06-19 end date = 2011-06-25
Week 5-> start date = 2011-06-26 end date = 2011-07-02He gave the impression that he just wants the dates of that particular month:
1st week -> Start date=2011-01-01 End date=2011-01-01
2nd week -> Start date=2011-01-02 End date=2011-01-08
3rd week -> Start date=2011-01-09 End date=2011-01-15
4th week -> Start date=2011-01-16 End date=2011-01-22
5th week -> Start date=2011-01-23 End date=2011-01-29
6th week -> Start date=2011-01-30 End date=2011-01-31
Thanks ardav, I though He wanted upto last date of week, Here is corrected code
<?php
$textdt="01 jan 2011";
$currdt= strtotime( $textdt);
$nextmonth=strtotime($textdt."+1 month");
$i=0;
$flag=true;
do
{
$weekday= date("w",$currdt);
$endday=abs($weekday-6);
$startarr[$i]=$currdt;
$endarr[$i]=strtotime(date("Y-m-d",$currdt)."+$endday day");
$currdt=strtotime(date("Y-m-d",$endarr[$i])."+1 day");
if($endarr[$i]>=$nextmonth)
{
$endarr[$i]=strtotime(date("Y-m-d",$nextmonth)."-1 day");;
$flag=false;
}
echo "Week ".($i+1). "-> start date = ". date("Y-m-d",$startarr[$i])." end date = ". date("Y-m-d",$endarr[$i])."<br>";
$i++;
}while($flag);
