Zip a folder (include itself).
Usage:
  HZip::zipDir('/path/to/sourceDir', '/path/to/out.zip');

<?php
class HZip
{
 
/**
   * Add files and sub-directories in a folder to zip file.
   * @param string $folder
   * @param ZipArchive $zipFile
   * @param int $exclusiveLength Number of text to be exclusived from the file path.
   */
 
private static function folderToZip($folder, &$zipFile, $exclusiveLength) {
   
$handle = opendir($folder);
    while (
false !== $f = readdir($handle)) {
      if (
$f != '.' && $f != '..') {
       
$filePath = "$folder/$f";
       
// Remove prefix from file path before add to zip.
       
$localPath = substr($filePath, $exclusiveLength);
        if (
is_file($filePath)) {
         
$zipFile->addFile($filePath, $localPath);
        } elseif (
is_dir($filePath)) {
         
// Add sub-directory.
         
$zipFile->addEmptyDir($localPath);
         
self::folderToZip($filePath, $zipFile, $exclusiveLength);
        }
      }

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

        case
ZipArchive::ER_MEMORY       : return 'N Malloc failure';
        case

        case

        case

Hi there.
I just wrote a little function to zip a whole folder while maintaining the dir-structure. I hope it might help someone.

<?php
function folderToZip($folder, &$zipFile, $subfolder = null) {
    if (
$zipFile == null) {
       
// no resource given, exit
       
return false;
    }
   
// we check if $folder has a slash at its end, if not, we append one
   
$folder .= end(str_split($folder)) == "/" ? "" : "/";
   
$subfolder .= end(str_split($subfolder)) == "/" ? "" : "/";
   
// we start by going through all files in $folder
   
$handle = opendir($folder);
    while (
$f = readdir($handle)) {
        if (
$f != "." && $f != "..") {
            if (
is_file($folder . $f)) {
               
// if we find a file, store it
                // if we have a subfolder, store it there
               
if ($subfolder != null)
                   
$zipFile->addFile($folder . $f, $subfolder . $f);
                else
                   
$zipFile->addFile($folder . $f);
            } elseif (
is_dir($folder . $f)) {
               
// if we find a folder, create a folder in the zip
               
$zipFile->addEmptyDir($f);
               
// and call the function again
               
folderToZip($folder . $f, $zipFile, $f);
            }
        }
    }
}
?>

Use it like this:
<?php
$z
= new ZipArchive();
$z->open("test.zip", ZIPARCHIVE::CREATE);
folderToZip("storeThisFolder", $z);
$z->close();
?>

Have a good day!

Important: Due to the natural file size limit of 4GB (~3,6GB to be correct) of zip files, this class will generate corrupt files of the result is larger than 4 GB. Using tar.gz is a proper alternative.

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.

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 );
}
?>

You can check general purpose flag to test if the zip file is encrypted. Example function below.

<?php

/**
* Check if the file is encrypted
*
* Notice: if file doesn't exists or cannot be opened, function
* also return false.
*
* @param string $pathToArchive
* @return boolean return true if file is encrypted
*/
function isEncryptedZip( $pathToArchive ) {
   
$fp = @fopen( $pathToArchive, 'r' );
   
$encrypted = false;
    if (
$fp && fseek( $fp, 6 ) == 0 ) {
       
$string = fread( $fp, 2 );
        if (
false !== $string ) {
           
$data = unpack("vgeneral", $string);
           
$encrypted = $data[ 'general' ] & 0x01 ? true : false;
        }
       
fclose( $fp );
    }
    return
$encrypted;
}

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);}
    }

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.

Simple class xZip to zip big folders into multiple parts and unzip multi zip files at once.

<?php
class xZip {
    public function

glob($source . "/*/") as $key => $value) {
           
$this->_rglobRead(str_replace("//", "/", $value), $array);
        }
   
        foreach ((array)
glob($source . "*.*") as $key => $value) {
           
$array[] = str_replace("//", "/", $value);
        }
    }
    private function

mkdir($destination, 0777, true);

$zip->addFile($value, str_replace(array("../", "./"), NULL, $value));

$zip->close();

        for(
