Sorting files from a folder

I am using the below php codes to get all files from a folder logfiles_patient

$path = "logfiles_patient/";
    // Open the folder
    $dir_handle = @opendir($path) or die("Unable to open $path");
    // Loop through the files
    while ($file = readdir($dir_handle)) 
    {
        if(($file!='.')&&($file!='..'))
        {
    echo "<a target='_blank' href='log_Patient_download.php?filename=$file'>$file</a>";
        }
    }
    // Close
    closedir($dir_handle);

and the output echoed is 

March 19, 2014.txt
March 20, 2014.txt
March 21, 2014.txt

I want to rearrange the the output as 

March 21, 2014.txt
March 20, 2014.txt
March 19, 2014.txt

I suggest you try something like this:

$files = glob('logfiles_patient/*');
if(is_array($files)){
    foreach ($files as $file){
        $coll[basename($file)] = filemtime($file);
    }
    asort($coll);
    $files = array_keys($coll);
}

Bear in mind that if glob() encounters an error, it will return false.

You can store temporarily your $file var in an array, and applying sorting functions after the while loop.

Like this:

$array = array();    

while ($file = readdir($dir_handle))
{
     if(($file!='.')&&($file!='..'))
          $array[] = $file;
}

$array = arsort($array);

foreach($array as $file)
    echo "<a target='_blank' href='log_Patient_download.php?filename=$file'>$file</a>";
