Help with calculating weekly event

pixelita

I found a PHP script on the net which would calculate an event that occurs on, for example, the 2nd Tuesday of each month.

I tried Googling to find a similar script that would output a weekly event, e.g., every Friday.

I tried modifying the original script by poking around php.net, but I know just enough to be dangerous.

Here is the script:

<?php 
$t=getdate();
$today = mktime(0,0,0,$t['wday'],$t['year']);

$this_week_start = mktime(0,0,0,$t['wday'],1,$t['year']);
if ($t['wday'] == 0) {
$next_week_start = mktime(0,0,0,0,1,$t['year']+1);
} else {
$next_week_start = mktime(0,0,0,$t['wday']+1,1,$t['year']);
}

$this_week_date = strtotime("Sunday",$this_week_start);
$next_week_date = strtotime("Sunday",$next_week_start);

if($today <= $this_week_date) {
	$event_date = $this_week_date;
} else {
	$event_date = $next_week_date;
}
print "Sunday, ".date('F j, Y',$event_date)." at 11:00 a.m., Steak Kountry Buffet, 1010 Antoine Drive, Houston, Texas";

What it's doing now is outputting July 1, 2012 at 11:00 a.m. rather than the next recurring Sunday, which is March 19, 2012. I think my error lies within "mktime" but am not sure.

Any ideas? Thanks!

You can get a timestamp for the second Tuesday of March (for example) by using strtotime("second Tuesday of March").

Yes, I know that. The original script I found and am using on our Civic Club web site does just that, it calculates the next board meeting date which is the second Tuesday of each month.

I am trying to calculate something different here, every Sunday. I took that original script and attempted to modify it and posted the modified code. I am doing something wrong (I suspect with mktime) because it spits out Sunday, June 30 rather than the next upcoming Sunday, which is Sunday, March 18.

I found this solution and it works nicely:

<?php 
    $startdate=strtotime("next Friday"); 
    $enddate=strtotime("+1 weeks",$startdate); //1 week from the starting date
    $currentdate=$startdate;

echo "<ul>";
while ($currentdate < $enddate): //loop through the dates
    echo "\t <li>Friday,<strong>",date('F j', $currentdate),"</strong>, 6:00 p.m., Golden Seafood Restaurant, 903 South 75th Street, Houston, Texas</li>";
    $currentdate = strtotime("+1 week", $currentdate); //increment the current date
endwhile; // calculate date range
echo "</ul>";
?>
