Noobie needs help w/ filectime

[tomtomdotcom]

I'm fooling around with this script that copys a file from a remote url to my server this works fine

 

<?php

$file = 'http://www.somecoolsite.com/imgs/pic.jpg';

$newfile = 'Imgs/pic.jpg';

 

if (!copy($file, $newfile)) {

    echo "failed to copy $file...\n";

}

?>

 

this file pic.jpg will be changed on the remote site every 24hrs

so I need this script to first check if the time elapsed since last copied is greater than 24hrs then to copy it again/update it.

How would i go about this? I'm a newbie so please be specific.

Thanks

well I managed to get this working, thought I'd share this:

this will every 6 hours copy the new file from the remote website to my server directory

 

<?php
$sourcefile = 'http://www.remotesite.com/imgs/pic.jpg';
$localfile = 'Imgs/pic.jpg';

      $Diff = (time() - filectime("$localfile"));

if ($Diff > 21600) {
	(copy($sourcefile, $localfile));
}
?>

then I have another php file that loads the pic on my website:

 

<?php

@include('http://www.mywebsite.com/abovefile.php'); //this will run the above php script every time the page is loaded

$botd= "/Imgs/pic.jpg";
$link= "/Imgs/pic.jpg";

$caption = "Babe Of The Day";
$block = "
<div style='text-align:left'><a href='$link' target='_blank'><img src='$botd' width='160' border='0'/></a></div>"; 
$ns -> tablerender($caption, $block); 
?>

Hope someone else can benefit from my hors of noobing around with this

Big thanks to all who responded to my plea for help
