There is a usefull function to get the ZipArchive status as a human readable string :

<?php
function ZipStatusString( $status )
{
    switch( (int) $status )
    {
        case ZipArchive::ER_OK           : return 'N No error';
        case ZipArchive::ER_MULTIDISK    : return 'N Multi-disk zip archives not supported';
        case ZipArchive::ER_RENAME       : return 'S Renaming temporary file failed';
        case ZipArchive::ER_CLOSE        : return 'S Closing zip archive failed';
        case ZipArchive::ER_SEEK         : return 'S Seek error';
        case ZipArchive::ER_READ         : return 'S Read error';
        case ZipArchive::ER_WRITE        : return 'S Write error';
        case ZipArchive::ER_CRC          : return 'N CRC error';
        case ZipArchive::ER_ZIPCLOSED    : return 'N Containing zip archive was closed';
        case ZipArchive::ER_NOENT        : return 'N No such file';
        case ZipArchive::ER_EXISTS       : return 'N File already exists';
        case ZipArchive::ER_OPEN         : return 'S Can\'t open file';
        case ZipArchive::ER_TMPOPEN      : return 'S Failure to create temporary file';
        case ZipArchive::ER_ZLIB         : return 'Z Zlib error';
        case ZipArchive::ER_MEMORY       : return 'N Malloc failure';
        case ZipArchive::ER_CHANGED      : return 'N Entry has been changed';
        case ZipArchive::ER_COMPNOTSUPP  : return 'N Compression method not supported';
        case ZipArchive::ER_EOF          : return 'N Premature EOF';
        case ZipArchive::ER_INVAL        : return 'N Invalid argument';
        case ZipArchive::ER_NOZIP        : return 'N Not a zip archive';
        case ZipArchive::ER_INTERNAL     : return 'N Internal error';
        case ZipArchive::ER_INCONS       : return 'N Zip archive inconsistent';
        case ZipArchive::ER_REMOVE       : return 'S Can\'t remove file';
        case ZipArchive::ER_DELETED      : return 'N Entry has been deleted';
       
        default: return sprintf('Unknown status %s', $status );

Here is a simple function which zips folders with all sub folders or only a simple file... the $data var can be a string or an array...

<?php
public function un_zip($data,$arcpf,$mode='zip',$obj=''){
        $absoluterpfad = 'YOUR_BASE_PATH';
        $arcpf = $absoluterpfad.DS.$arcpf;
        if(is_object($obj)==false){
             $archiv = new ZipArchive();
             $archiv->open($arcpf,ZipArchive::CREATE);
        }else{$archiv =& $obj;}
        if($mode=='zip'){
           if(is_array($data)==true){
                 foreach($data as $dtmp){
                     $archiv =& un_zip($dtmp,$arcpf,'zip',&$archiv);
                 }
           }else{
            if(is_dir($data)==true){
                    $archiv->addEmptyDir(str_replace($absoluterpfad.DS,'',$data));
                  $files = scandir($data);
               $bad = array('.','..');
               $files = array_diff($files,$bad);
               foreach($files as $ftmp){
                   if(is_dir($data.DS.$ftmp)==true){
                        $archiv->addEmptyDir(str_replace($absoluterpfad.DS,'',$data.'/'.$ftmp));
                        $archiv =& un_zip($data.DS.$ftmp,$arcpf,'zip',&$archiv);
                   }elseif(is_file($data.DS.$ftmp)==true){
                    $archiv->addFile($data.DS.$ftmp,str_replace($absoluterpfad.DS,'',$data.'/'.$ftmp));
                   }
                 }
            }elseif(is_file($data)==true){$archiv->addFile($data,str_replace($absoluterpfad.DS,'',$data));}
           }
        }
        if(is_object($obj)==false){$archiv->close();}
        else{return $archiv;}
        if($mode=='unzip'){$archiv->extractTo($data);}
    }
?>

The following code can be used to get a list of all the file names in a zip file.

<?php
$za = new ZipArchive();

$za->open('theZip.zip');

for( $i = 0; $i < $za->numFiles; $i++ ){
    $stat = $za->statIndex( $i );
    print_r( basename( $stat['name'] ) . PHP_EOL );
}
?>

Be wary that there are several algorithms to generate a zip file. I found that Office OpenXML files created with ZipArchive are not recognized by Excel 2007, for example.

You have to use a different class to zip in this case, such as PclZip.

Read a file from an archive to a variable.
A warning is printed automatically in case of a CRC32 mismatch, which we capture, so we can print our own error message.

<?php
$zip = new ZipArchive();
if ($zip->open('archive.zip')) {
  $fp = $zip->getStream('myfile.txt'); //file inside archive
  if(!$fp)
    die("Error: can't get stream to zipped file");
  $stat = $zip->statName('myfile.txt');

  $buf = ""; //file buffer
  ob_start(); //to capture CRC error message
    while (!feof($fp)) {
      $buf .= fread($fp, 2048); //reading more than 2156 bytes seems to disable internal CRC32 verification (bug?)
    }
    $s = ob_get_contents();
  ob_end_clean();
  if(stripos($s, "CRC error") != FALSE){
    echo 'CRC32 mismatch, current ';
    printf("%08X", crc32($buf)); //current CRC
    echo ', expected ';
    printf("%08X", $stat['crc']); //expected CRC
  }

  fclose($fp);
  $zip->close();
  //Done, unpacked file is stored in $buf
}
?>

To create a corrupt file, change a byte in a zip file using a hex editor.
