Question

I want to find a specific week number from the specific start date. For example $date is dragged from the database (i.e. 07/08/2011)

I want this to be the start date so it would be week 3 now from this date. This is the code i have so far but just shows the ISO version:

    $date = strtotime("".$row['start_date'].""); 
$weekNumber = date("W", $date); 
print $weekNumber;

I have googled for past two hours but cannot seem to find any thing that resolves this! any help would be great thanks!

Answer 1

Get the difference between now and the startdate, and then divide by seven days (7*86400 seconds)

<?php
    $startdate = strtotime("".$row['start_date'].""); 
    $enddate = time();

    $time_passed = $enddate - $startdate;

    // if the first day after startdate is in "Week 1" according to your count
    $weekcount_1 = ceil ( $time_passed / (86400*7));

    // if the first day after startdate is in "Week 0" according to your count
    $weekcount_0 = floor ( $time_passed / (86400*7));

?>
