Create a Zip File In PHP

by Bhumi // Apr 4,2012 // 1 comment.

Before Some days I have created one function with the use of zip archive class in PHP.For one site, I want to create zip file of all documents generated in one directory. so user can download all documents via single zip file and for that I have used Zip Archive Class of PHP So lets start it!

Zip file is a compressed file which can mainly stored as .zip extension and its well known compression format to gather datas and its very simple with PHP with Zip Archive class

To create zip File using PHP

Let’s see one example which shows you how to create zip file.Here, I have create one function which create zip file.


function Create_zip($source, $destination,$overwrite='')
{
  $zip = new ZipArchive();
  if($zip->open($destination,$overwrite?       ZIPARCHIVE::OVERWRITE:ZIPARCHIVE::CREATE)===TRUE)
 {
   $zip->addFile($source);// Add the files to the .zip file
   $zip->close(); // Closing the zip file
 }
}
Create_zip("file.php","Compressed.zip");

function Create_zip($source, $destination,$overwrite='')

{

$zip = new ZipArchive();

if($zip->open($destination,$overwrite? ZIPARCHIVE::OVERWRITE:ZIPARCHIVE::CREATE)===TRUE)

{

$zip->addFile($source);// Add the files to the .zip file

$zip->close(); // Closing the zip file

}

Create_zip("file.php","Compressed.zip");

To extract zip File using PHP

Now, Let’s see how to extract zip file


function Extract_zip($source, $destination)
{
  $zip = new ZipArchive(); // Call object of ZipArchive
    if ($zip->open($source) === TRUE)
      // Open Compressed.zip for   extracting all files
     {
      $destination = str_replace('\', '/', realpath($destination));
      // Will extract all files from master.zip to given path.
      $zip->extractTo($destination);
      $zip->close();
     }
}
Extract_zip("Compressed.zip", 'link/');

function Extract_zip($source, $destination)

{

$zip = new ZipArchive(); // Call object of ZipArchive

if ($zip->open($source) === TRUE)

// Open Compressed.zip for extracting all files

{

$destination = str_replace('\', '/', realpath($destination));

// Will extract all files from master.zip to given path.

$zip->extractTo($destination);

$zip->close();

}

Extract_zip("Compressed.zip", 'link/');

How to Zip a directory in PHP?

Upto now, We have checked how to zip and unzip file but now let’s see how to zip whole directory which contain multiple files.


public function create_zip($source,$destination,$overwrite=’’)
{
  if (!extension_loaded('zip') || !file_exists($source)) {
    return false;
   }
$zip = new ZipArchive();
$source = str_replace('\', '/', realpath($source));
// to replace path of path to real path
if (is_dir($source) === true)
{
  $files = new RecursiveIteratorIterator(new    RecursiveDirectoryIterator($source),
RecursiveIteratorIterator::SELF_FIRST);
  foreach ($files as $file)
   {
     $file = str_replace('\', '/', realpath($file));
     $ext = substr(strrchr($file,'.'),1); 
     // To get extension of files in directory
     if($ext=='zip')
        {
          unlink($file);
         // if overwrite file,its overwrite zip folder
         // also within a directory so will unlink it
         continue;
        }
   }
if (!$zip-&gt;open($destination,$overwrite?ZIPARCHIVE::OVERWRITE:ZIPARCHIVE::CREATE))
{
    return false;
}
if (is_dir($source) === true)
{
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source),
RecursiveIteratorIterator::SELF_FIRST);
//To find all the files (recursively) in a certain directory
foreach ($files as $file)
{
   if (is_dir($file) === true)
   {
     $zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
   }
   else if (is_file($file) === true)
   {
      $zip->addFromString(str_replace($source . '/', '',
$file), file_get_contents($file));
      //To add a file to a ZIP archive with the use of its contents
   }
 }
}
else if (is_file($source) === true)
{
   $zip->addFromString(basename($source),      file_get_contents($source));
}
return $zip->close();
}
}

public function create_zip($source,$destination,$overwrite=’’)

{

if (!extension_loaded('zip') || !file_exists($source)) {

return false;

}

$zip = new ZipArchive();

$source = str_replace('\', '/', realpath($source));

// to replace path of path to real path

if (is_dir($source) === true)

{

$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source),

RecursiveIteratorIterator::SELF_FIRST);

foreach ($files as $file)

{

$file = str_replace('\', '/', realpath($file));

$ext = substr(strrchr($file,'.'),1);

// To get extension of files in directory

if($ext=='zip')

{

unlink($file);

// if overwrite file,its overwrite zip folder

// also within a directory so will unlink it

continue;

}

if (!$zip->open($destination,$overwrite?ZIPARCHIVE::OVERWRITE:ZIPARCHIVE::CREATE))

{

return false;

}

if (is_dir($source) === true)

{

$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source),

RecursiveIteratorIterator::SELF_FIRST);

//To find all the files (recursively) in a certain directory

foreach ($files as $file)

{

if (is_dir($file) === true)

{

$zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));

}

else if (is_file($file) === true)

{

$zip->addFromString(str_replace($source . '/', '',

$file), file_get_contents($file));

//To add a file to a ZIP archive with the use of its contents

}

else if (is_file($source) === true)

{

$zip->addFromString(basename($source), file_get_contents($source));

}

return $zip->close();

}
