Folder/
  index.html

Answer 1

This is a function that zips a whole folder and its contents in to a zip file and you can use it simple like this :

addzip ("path/folder/" , "/path2/folder.zip" );

function :

// compress all files in the source directory to destination directory 
    function create_zip($files = array(), $dest = '', $overwrite = false) {
    if (file_exists($dest) && !$overwrite) {
        return false;
    }
    if (($files)) {
        $zip = new ZipArchive();
        if ($zip->open($dest, $overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) {
            return false;
        }
        foreach ($files as $file) {
            $zip->addFile($file, $file);
        }
        $zip->close();
        return file_exists($dest);
    } else {
        return false;
    }
}

function addzip($source, $destination) {
    $files_to_zip = glob($source . '/*');
    create_zip($files_to_zip, $destination);
    echo "done";
}

Answer 2

Use this function:

function zip($source, $destination)
{
    if (!extension_loaded('zip') || !file_exists($source)) {
        return false;
    }

    $zip = new ZipArchive();
    if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
        return false;
    }

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

    if (is_dir($source) === true) {
        $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);

        foreach ($files as $file) {
            $file = str_replace('\\', '/', $file);

            // Ignore "." and ".." folders
            if (in_array(substr($file, strrpos($file, '/')+1), array('.', '..'))) {
                continue;
            }               

            $file = realpath($file);

            if (is_dir($file) === true) {
                $zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
            } elseif (is_file($file) === true) {
                $zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
            }
        }
    } elseif (is_file($source) === true) {
        $zip->addFromString(basename($source), file_get_contents($source));
    }

    return $zip->close();
}

Example use:

zip('/folder/to/compress/', './compressed.zip');

Answer 3

This will resolve your issue. Please try it.

$zip = new ZipArchive;
$zip->open('testPDFZip.zip', ZipArchive::CREATE);
foreach (glob(APPLICATION_PATH."pages/recruitment/uploads/test_pdf_folder/*") as $file) {
    $new_filename = end(explode("/",$file));
    $zip->addFile($file,"emp/".$new_filename);
}           
$zip->close();

Answer 4

This is a working example of making ZIPs in PHP:

$zip = new ZipArchive();
$zip_name = time().".zip"; // Zip name
$zip->open($zip_name,  ZipArchive::CREATE);
foreach ($files as $file) {
  echo $path = "uploadpdf/".$file;
  if(file_exists($path)){
  $zip->addFromString(basename($path),  file_get_contents($path));---This is main function  
  }
  else{
   echo"file does not exist";
  }
}
$zip->close();

Answer 5

Use this is working fine.

$dir = '/Folder/';
$zip = new ZipArchive();
$res = $zip->open(trim($dir, "/") . '.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);
if ($res === TRUE) {
    foreach (glob($dir . '*') as $file) {
        $zip->addFile($file, basename($file));
    }
    $zip->close();
} else {
    echo 'Failed to create to zip. Error: ' . $res;
}

Answer 6

I tried with the code below and it is working. The code is self explanatory, please let me know if you have any questions.

<?php
class FlxZipArchive extends ZipArchive 
{
 public function addDir($location, $name) 
 {
       $this->addEmptyDir($name);
       $this->addDirDo($location, $name);
 } 
 private function addDirDo($location, $name) 
 {
    $name .= '/';
    $location .= '/';
    $dir = opendir ($location);
    while ($file = readdir($dir))
    {
        if ($file == '.' || $file == '..') continue;
        $do = (filetype( $location . $file) == 'dir') ? 'addDir' : 'addFile';
        $this->$do($location . $file, $name . $file);
    }
 } 
}
?>

<?php
$the_folder = '/path/to/folder/to/be/zipped';
$zip_file_name = '/path/to/zip/archive.zip';
$za = new FlxZipArchive;
$res = $za->open($zip_file_name, ZipArchive::CREATE);
if($res === TRUE) 
{
    $za->addDir($the_folder, basename($the_folder));
    $za->close();
}
else{
echo 'Could not create a zip archive';
}
?>
