Help me sort files by date?

[Moron]

I'm displaying the contents of a folder, with each file clickable.

 

I can't seem to get it to sort by file date, with the most current on top (descending).

 

What am I missing here?

 

 

<?php

echo "<h1>File Listing</h1>";

$content_array = array();


$path = "../FOLDER/Subfolder/";

$dh = opendir($path);

$handle=opendir($dirname);
$i=0;
while (($file = readdir($dh)) !== false) {


if ($file != "." && $file != "..")
{
       $content_array[$i][0] = $file;
       $content_array[$i][1] = date ("Y m d", filemtime($dirname."/".$file));
        $i++;
}

foreach($content_array as $res)
       $sortAux[] = $res[1];
    array_multisort($sortAux, SORT_DESC, $content_array);

    echo "<a href='$path/$file' target=\"\_blank>$file</a><br />";
}
closedir($dh);
?>

$where = "path/";

chdir($where);

array_multisort(array_map('filemtime', ($files = glob("*.*"))), SORT_DESC, $files);

var_dump($files);

$where = "path/";
chdir($where);
array_multisort(array_map('filemtime', ($files = glob("*.*"))), SORT_DESC, $files);
var_dump($files);

 

Very nice!

 

One liner:

array_multisort(array_map('filemtime', ($files = array_map('basename', $files = glob("path/*.*")))), SORT_DESC, $files);

Sorry to be so dense, but I don't write PHP every day.

 

How do I integrate this into my existing code?

[Moron]

In other words, my code does exactly what I want except for the sorting.

You had a lot of unneeded code. The one line lists all files and sorts them by date descending. There are different ways to handle the path, but this should work fine:

$path = "../FOLDER/Subfolder";
array_multisort(array_map('filemtime', ($files = glob("$path/*.*"))), SORT_DESC, $files);

foreach($files as $file) {
    echo "<a href='$file' target=\"\_blank>".basename($file)."</a><br />";
}

Thanks. That's closer, but it's sorting by file name (descending) and I need it to sort by file modified date (also descending, newest on top).

Not for me it's not.

Ah. You're absolutely right I ot momentarily confused by the file names.

 

Thanks a ton!

Just for completeness, because I could see someone coming back and asking, if you want to store/use the dates as well:

array_multisort(($times = array_map('filemtime', ($files = glob("$path/*.*")))), SORT_DESC, $files);

foreach($files as $i => $file) {
    echo "<a href='$file' target=\"\_blank>".basename($file)."</a> : ".date("Y-m-d", $times[$i])."<br />\n";
}

Now there's a weird problem. I navigate to the folder in Windows Explorer and click a file, it has tons of information. I click it from this PHP page and it has just a couple of lines. It's obviously a different file, but the names match exactly.

 

This is total Twilight Zone.

 

Ideas?

What type of file?

[Moron]

Aha! For some crazy reason, it will display one file name, but point to a different one!

 

So where's the bug?

[Moron]

What type of file?

 

They're plain ASCII text files.

[AbraCadaver]

They're plain ASCII text files.

 

And when you open in Windows Explorer and from the browser do they open in the same app?

[Moron]

No, From Windows Explorer, they open in Notepad. From the browser, they open in a browser window.

 

You can hover the mouse over each file listed and look at the bottom bar of the browser, and it will be pointing to a different file name. That's why they aren't matching.

[AbraCadaver]

If that is really the case, then it is probably because you are using the relative ../path/etc.

Yes, I'm using a relative path. If I use the full path (http://server/folder/subfolder, etc.....), it crashes.
