How do I display folders in date of creation order?

Question

I am new to PHP and developing a project called BaboonHut.com, I am coding it in PHP as the best way to learn is by just diving in. Anyway to the question, the snippet of code below currently gets the name of all the folders in a certain location and displays some information, however the items are currently displaying in alphabetical order and I would like them to display in order of folder creation. SimpleHost should be in front of Code-Game-Sleep http://www.baboonhut.com/resources/, Thanks in advance.

<?php
$dir = 'resources/';

foreach(glob($dir.'*', GLOB_ONLYDIR) as $resdir) {
    $resdir = str_replace($dir, '', $resdir);
    echo "
<div class=\"span3\">
<div class=\"tile\">
<img src=\"resources/". $resdir ."/thumbnail.png\" class=\"img-rounded\">
<h3 class=\"tile-title\">". $resdir ."</h3>
<p>"; echo  include('resources/'. $resdir .'/description.txt'); echo "</p>
<a class=\"btn btn-primary btn-large btn-block\" href=\"http://www.baboonhut.com/resources/" . $resdir ."/\">More Information</a>
</div>
</div>
"
;
}
?>

Sorry about that, I included it in pastebin as I thought it would be less messy :P — TheGiantBaboon, May 31 '13 at 20:20

This will grab a list of files from a directory put them into an array then sort the array by date.

<?php
$dir = 'resources/';
$files = [];

foreach(glob($dir.'*', GLOB_ONLYDIR) as $resdir) {
    $files[] = [
        "name" => $resdir,
        "time" => filectime($resdir)
    ];
}

// Sort files by date
usort($files, function($a, $b){
    return $b["time"] - $a["time"];
});

foreach($files as $resdir) {
    $resdir = str_replace($dir, '', $resdir);
    echo <<<HTML
    <div class="span3">
    <div class="tile">
    <img src="resources/$resdir/thumbnail.png" class="img-rounded">
    <h3 class="tile-title">$resdir</h3>
    <p>
HTML;
    readfile('resources/'. $resdir .'/description.txt'); 
    echo <<<HTML
    </p>
    <a class="btn btn-primary btn-large btn-block" href="http://www.baboonhut.com/resources/$resdir/">More Information</a>
    </div>
    </div>
HTML;
}

How would I change this to grab directories instead of files? – TheGiantBaboon May 31 '13 at 20:28
This does get directories instead of files. – Get Off My Lawn May 31 '13 at 20:30
How would I merge this code with the snippet I included? as in, what would I keep and what would I replace? – TheGiantBaboon May 31 '13 at 20:34
Use HEREDOC it is a bit more readable with that much HTML in a string. You may be getting a 500 because a file doesn't exist. check your log files. – Get Off My Lawn May 31 '13 at 20:47
Ah yes, the log says "File does not exist: /var/www/resources/js, referer: http://www.baboonhut.com/resources/" Why is it trying to get to a JS folder – TheGiantBaboon May 31 '13 at 20:54
Ah, Nope, I added that in and still nothing :/ – TheGiantBaboon May 31 '13 at 21:00
do a `var_dump($resdir)` maybe it isn't pointing to the correct spot – Get Off My Lawn May 31 '13 at 21:03
Nope its pointing the the right place alright, do you have skype, might be better to talk on their than spamming up the comments. Skype: wpcheese – TheGiantBaboon May 31 '13 at 21:07

You can't beat DirectoryIterator.

$files = array();
$dir = new DirectoryIterator('.');
foreach ($dir as $fileinfo) {
   // Add only directories into a associative array, that key is it `MTime`
   if($fileinfo->isDir()){
       $files[$fileinfo->getMTime()] = $fileinfo->getFilename();
   }
}

// Then, key sort it.
ksort($files);

Using Creation Date

$files = glob(__DIR__ . '/*', GLOB_ONLYDIR);

// Using Creation Date
usort($files, function ($a, $b) {
    return filetime($a) - filetime($b);
});

foreach($files as $file) {
    printf("%s : %s\n", date("r", fileatime($file)), $file);
}

function filetime($file) {
    return PHP_OS == "win" ? fileatime($file) : filectime($file);
}

Using Modification Date

$files = glob(__DIR__ . '/*', GLOB_ONLYDIR);

// Using Modification Date
usort($files, function ($a, $b) {
    return filemtime($a) - filemtime($b);
});

foreach($files as $file) {
    printf("%s : %s\n", date("r", fileatime($file)), $file);
}

Note : Using $a - $b in descending other but if you want descending please use $b - $a
