Changing file names

Ghost429

I have no Idea how to do this, or if it's even feasable, bu here it goes:
I want to have my Live Journal use a different file as its background every day or so. Currently It gets the image I want off of the server I am hosting off of my computer. What I want is a script that will switch the filenames of two images in a directory automatically, so my Live Journal will load the same image name, but it would be a different image.

Please say so If this doesnt make any sense or is not possible. Thanks

Sure, you'd just have to have a cron job run it on the day you want it changed.

/* move current to backup */
mv /path/to/image.jpg /path/to/image.jpg.backup
/* move current backup to usable image */
mv /path/to/image.jpg.back /path/to/image.jpg
/* move backup file to backup name for when it next time */
/path/to/image.jpg.backup /path/to/image.jpg.back

Stick something like that in cron on the days you want to run it, and you should be golden.

<?
rename("/home/user/public_html/images/image1.jpg", "/home/user/tmp/image2.jpg");
rename("/home/user/public_html/images/image2.jpg", "/home/user/public_html/images/image1.jpg");
rename("/home/user/tmp/image2.jpg", "/home/user/public_html/images/image2.jpg");
?>

Why not just look to see if it's an even or an odd day?

if(date("j")%2==0){/*specify one file name*/}else{/*specify the other file name*/}

** edit: HA! THAT won't work. well it does today, but it's the 4th . I'll have to expand that.

What about specifying days of the month you want to switch up in an array?

$dayArray = array(1,2,5,6,9,19,13,14,17,18,21,22,25,26,29,30);
if(in_array(date("j"),$dayArray)){/*specify file one*/}else{/*specify file two*/}

just seems more straightforward than copying back and forth all the time, at least to me. :p

Hey, thanks alot, guys. I got it to work. Now my question is how can I get it to run the script on its own say, every day?
BTW, Im running easyPHP on Windows, not linux
A solution using mysql would be the easiest thing to do, i think...

Oh, and Sphynx, LJ wont let me use PHP in my page...

edit
Never mind, guys. I got it to work. Thanks for the help!

Same concept, except instead of putting a script in cron, make a batch file and put it in th Windows Task Scheduler.
