How to sort array with files on date

[OrangeTux]

Hello,

 

I'm making a imagegallery and when someone upload a new image that image has to appear as first picture of the gallery.

I'm using an array for the files, but how can I sort the files on date, newest first.?

<?php
$n = 0;
$pathToThumbs = "images/tekeningen/";
$dir = opendir( $pathToThumbs );
while (false !== ($fname = readdir($dir))){
	    
	    // strip the . and .. entries out
    	if ($fname != '.' && $fname != '..'){
    		$tekeningen[$n] = $fname;
   	} echo $tekeningen[$n]."<br />"; 
   	 $n = $n +1;
}
   closedir( $dir );
?>

 

I found solutions with ksort and filemtime, but I don't understand them and/or they didn't work for me.

To be able to sort the filenames by date you have to store the names and dates in an array, sort the array and then display the information on the screen, for example:

<?php
$pathToThumbs = "images/tekeningen/";
$f = glob($pathToThumbs . '/*');
$tmp = array();
foreach ($f as $file) {
   $tmp[$file] = filemtime($file);
}
arsort($tmp);
foreach ($tmp as $file => $time) {
   echo basename($file) . "<br>\n";
}
?>

It works half. I'm on a Linux system, btw, I don't know if that is a part of the problem.

 

When I copy existing file's to the folder, the files are sorted random. They aren't sorted on physical place.

But when I create new files in that folder these file's are sorted correct.

 

What can be the problem?

Please post the code you're using. I tested my code on a Linux system.

I'm using the script that you've posted above.

-+But I know already the problem.-

 

When I copy an existing file to another folder the modification date won't change.

 

e.g.

x.txt is last modificated at 14:45 04-08-2010.

I copy x.txt to another folder at 17:00 04-08-2010.

x.txt in the new folder is still last modificited at 14:45 04-08-2010, not at 17:00 04-08-2010.

 

Is there a way I can fix this or can do a trick to solve the problem?

Use the Linux touch command to change the last modified date of the file after you copy it.
