include statement

biodun

Hello everyone,
I am a newbie in php, I have just designed a site which uses an include statement to load part of the page contents from a text file (which I name based on dates, so that the pages wil be dynamic).
It works great, but I also want the script to load the last available text file if the one that is supposed to be loaded is not available. Here is the code
<....
$name=gmdate (dmy);
include ("p".$name.".txt);
...>
so a file name with p090402.txt will be loaded on 9th of April, 2002 and a file p100402.txt will be loaded on 10th of April, 2002, and so on..... However, on 12th of April, there is no p120402.txt (lets say we have p124002.txt due to saving error). then I want the script to load the closest available file (in this instance, that will be p110402.txt), I hope you get my picture.
Thanks your help.

Check if file exists, if not subtract a day from current time and generate new file name and so on....

<?php
function load_file($date){
if ($date< 1000000000 ) die; // date of first file
$name=gmdate ("dmy", $date);
if (file_exists("p".$name.".txt"))
{include ("p".$name.".txt");}
else
{load_file($date-86400);};
}
load_file(time());

Hi Guys,
The code tip you gave me work perefctly but I realized a weakness in my date format.
it reads \"dmy\" which will produce the sequence 100402, 110402,... and so on. for the deduction technique in file loading this is OK, but a month later, \"dmy\" will read 010502, 020502, ...., 200502, which is obviously irregular for the file loading to work when a file is missing. So I change the format \"ymd\" this way all the date will be increamental and as such a deduction will be possible especially from one month to another. But the problem is that it doesn\'t work perfectly, kindly help.

<?php
function load_file($date){
if ($date<020409) die; // date of first file
$name=gmdate (\"ymd\", $date);
if (file_exists(\"p\".$name.\".txt\"))
{include (\"p\".$name.\".txt\");}
else
{load_file($date-000001);};
}
load_file(time());
?>
