I've gotten the one array down and I've figured out how to sort that

// Loop through all files
while(false !== ($file = readdir($handle))){
// Ignore hidden files
if(!preg_match("/^\./", $file)){
// Put dirs in $dirs[] and files in $files[]
if(is_dir($file)){
$dirs[] = $file;
}else{
$files[] = $file;
}

// Close directory
closedir($handle);
// if $files[] exists, sort it and print all elements in it.
if(is_array($files)){
//HERE IS MY CURRENT SORT WHICH I KNOW I NEED TO CHANGE BUT AM UNSURE HOW
sort($files);
foreach($files as $file){
$completeFileName = $dir . $file;
//I WANT TO SORT BY THIS
echo date("m-d-Y", filemtime($completeFileName)) . "<br>";
}
}
}

Any ideas on how to fix this? Thanks
We need to see what is in the array, not just how you think you need to
manipulate it.
Show us the basic structure of the array, with a few examples of data
that would represent what you would normally be building the table out of.
Then, with that, we might be able to start helping you.
Diogo, thanks for cleaning up the code so I could realize what the OP was
trying to do.
Here is an example I did a few weeks ago on how to use the array_multi_sort()
function. I didn't get any feedback from the op to say if it actually fixed
his problem, but it worked for me.

ok, here would be my version of this code.
<pre><?php
$dir = './';
$filepattern = '*';
$sorting_list = array();
$filemtimes = array();
# Get file/dir listing, else error message
if ( ( $list = glob( $dir . $filepattern ) ) !== false ) {
foreach ( $list AS $file ) {
$filemtime = filemtime( $dir . $file );
# Build array to be sorted with filename and filemtime
$sorting_list[] = array('filename' => $file,
'filemtime' => $filemtime,
);
# This is the list of filemtimes to sort by later
$filemtimes[] = $filemtime;
}
# Sort array based on $filemtimes
# http://php.net/array-multisort Example #3
if ( array_multisort($filemtimes, SORT_DESC, $sorting_list) ) {
echo "List was sorted by filemtime\n";
} else {
echo "List was not sorted by filemtime\n";
}
var_dump($sorting_list);
} else {
echo 'Directory listing call failed!';
}
?>
Now, Diogo's version would work, except if you had two files with the same
access time. One would overwrite the other in the $files_new array.
change this line:
$files_new[filemtime( $dir . '/' . $file )] = $file;
To this:
$files_new[$file] = filemtime( $dir . '/' . $file );
then change the ksort() call to a sort() instead.
