Getting a filename according to date

[KeeganWolf]

Hi,

 

I just can't seem to figure this out. I have a system that parses information from a zip file according to the store number and date on a daily basis. It's always in the format of e.g. store 5081...

 

S508106142009-06152009.zip

 

Suddenly I have files coming in with 2 days between like.

 

S508106132009-06152009.zip

 

Which my code can't currently handle. This code tends to come out with a weird number for $daybefore

 

$today = date("md20y");
//		echo "Today is ",$today, "<br />";
$tomorrow = mktime(0, 0, 0, date("m"), date("d")+1, date("y"));
//		echo "Tomorrow is ".date("md20y", $tomorrow),"<br />"; 
$yesterday = mktime(0, 0, 0, date("m"), date("d")-1, date("y"));
$daybefore = mktime(0, 0, 0, date("m"), date("d")-2, date("y"));
//		echo "Day before ----> ", $daybefore, "<br />";
//		echo "Yesterday was ".date("md20y", $yesterday),"<br />";
//		echo "Your store number is ",$store, "<br />";
//		echo "Your store's filename will be S", $store,"".date("md20y", $yesterday), "-", $today, ".zip<br />";
$prevfile = 'S'.$store.date('md20y', $daybefore).'-'.$yesterday.'.zip';
$filename = 'S'.$store.date('md20y', $yesterday).'-'.$today.'.zip';
//		echo "Previous filename is", $prevfile; 

 

I'm sure theres a better way of doing this, like only getting the newest filename as a value.

 

Any ideas?
