I've gotten the one array down and I've figured out how to sort that array, however, I need to sort the array by the modified date of the file. Here's
what I got so far:

<?php
// Open current directory
if($handle = opendir($dir)){
// 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

Hi,

<?php
$dir        = '/tmp';
$files        = scandir( $dir);
$files_new    = array( );

foreach( $files as $file ) {
    if( strrpos( $file, 'sess_' ) !== false ) {
        $files_new[filemtime( $dir . '/' . $file )] = $file;

this totally breaks because file modification time is only accurate
to a second (many files can be modified in that time) ... appending
the file name to the key will fix that:

    $files_new[filemtime( $dir . '/' . $file ).$file] = $file;


or flip the association around, because files are uniq and that file can only have one modification time.

    }
}

ksort( $files_new );
var_dump( $filesnew );
?>
