Php Calculating the week number for a given date

[kamal213]

Hi guys!

 

This will seem complex but I really need your help

 

If a have a variable with a date value (i.e. $a = '23/10/2011') How do you work out the week number of that date?

 

Thanks

<?php
$a = '23/10/2011';
$dateStamp = strtotime($a); 
$week = date('W', $dateStamp); 
?>

That's not going to work without the date in the correct format. (23/10/2011 will result in week 01, should be 42). You require the date as follows: YYYY-MM-DD

 

<?php
$a = '2011-10-23';
$week_num =  date('W', strtotime($a));
echo $week_num;
?>

 

Use the php manual to find answers

thanks for the correction neil. Schoolboy error on my behalf. kamal213, if you need to convert uk into a week number then one option is:

<?php
list($day,$month,$year) = explode('/','15/11/2011');
$weekNumber = date('W',mktime(0,0,0,$month,$day,$year));
echo $weekNumber;
?>

cheers

Date Time formats accepted by strtotime() function (or most any PHP functions requiring it)
