Download multiple files as zip in PHP

<?php

/* create a compressed zip file */
function createZipArchive($files = array(), $destination = '', $overwrite = false) {

   if(file_exists($destination) && !$overwrite) { return false; }

   $validFiles = array();
   if(is_array($files)) {
      foreach($files as $file) {
         if(file_exists($file)) {
            $validFiles[] = $file;
         }
      }
   }

   if(count($validFiles)) {
      $zip = new ZipArchive();
      if($zip->open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) == true) {
         foreach($validFiles as $file) {
            $zip->addFile($file,$file);
         }
         $zip->close();
         return file_exists($destination);
      }else{
          return false;
      }
   }else{
      return false;
   }
}

$fileName = 'myzipfile.zip';
$files = array('uploads/profile1.jpeg', 'uploads/profile2.jpeg');
$result = createZipArchive($files, $fileName);

header("Content-Disposition: attachment; filename=\"".$fileName."\"");
header("Content-Length: ".filesize($fileName));
readfile($fileName);

php upload multiple files

When uploading multiple files, the $_FILES variable is created in the form:

Array
(
    [name] => Array
        (
            [0] => foo.txt
            [1] => bar.txt
        )

    [type] => Array
        (
            [0] => text/plain
            [1] => text/plain
        )

    [tmp_name] => Array
        (
            [0] => /tmp/phpYzdqkD
            [1] => /tmp/phpeEwEWG
        )

    [error] => Array
        (
            [0] => 0
            [1] => 0
        )

    [size] => Array
        (
            [0] => 123
            [1] => 456
        )
)

I found it made for a little cleaner code if I had the uploaded files array in the form

Array
(
    [0] => Array
        (
            [name] => foo.txt
            [type] => text/plain
            [tmp_name] => /tmp/phpYzdqkD
            [error] => 0
            [size] => 123
        )

    [1] => Array
        (
            [name] => bar.txt
            [type] => text/plain
            [tmp_name] => /tmp/phpeEwEWG
            [error] => 0
            [size] => 456
        )
)

I wrote a quick function that would convert the $_FILES array to the cleaner (IMHO) array.

<?php

function reArrayFiles(&$file_post) {

    $file_ary = array();
    $file_count = count($file_post['name']);
    $file_keys = array_keys($file_post);

    for ($i=0; $i<$file_count; $i++) {
        foreach ($file_keys as $key) {
            $file_ary[$i][$key] = $file_post[$key][$i];
        }
    }

    return $file_ary;
}

?>

Now I can do the following:

<?php

if ($_FILES['upload']) {
    $file_ary = reArrayFiles($_FILES['ufile']);

    foreach ($file_ary as $file) {
        print 'File Name: ' . $file['name'];
        print 'File Type: ' . $file['type'];
        print 'File Size: ' . $file['size'];
    }
}
