Is there a library for crating/extracting zip files in php?
The ZipArchive class works erratically, and this is mentioned on php.net : (for every function I checked)
ZipArchive::addEmptyDir (No version information available, might be only in CVS)

A:
Check PEAR Archive_Zip it might help you http://pear.php.net/package/Archive_Zip/docs/latest/Archive_Zip/Archive_Zip.html

A:
PHP has native Zip support via GZip (may not be enabled by default) http://us2.php.net/zlib
You can also use this class (Drupal is not part of this implementation) http://drupal.org/node/83253

The same module which includes ZipArchive also includes a number of functions which allow procedural access to zip files. This functionality is available in PHP 4 (since 4.0.7) and PHP 5 (since 5.2.0).
$zip = zip_open("foo.zip");
$files = [];
while ($entry = zip_read($zip)) {
zip_entry_open($zip, $entry);
$files[zip_entry_name($entry)] = zip_entry_read($entry, zip_entry_filesize($entry));
zip_entry_close($entry);
}
zip_close($zip);

Ok, I checked http://pear.php.net/package/Archive_Zip as posted by Irmantas,
but it says this :
"This package is not maintained anymore and has been superseded. Package has moved to channel pecl.php.net, package zip."
Then I searched pear.php.net and stumbled upon :
http://pear.php.net/package/File_Archive
File_Archive doesn't have a very intuitive set of methods though. But I wanted simple functionality of making a tar file, and extracting files from a tar file.
Following snippets achieve that : Extracting files from a tar file ->
<?php
require_once "File/Archive.php";
$tmp = 'output';
$t1 = 'check.tar';
File_Archive::setOption('tmpDirectory','tmp');
$r = File_Archive::extract(
File_Archive::read($t1.'/'),
File_Archive::toFiles($tmp)
);
?>
Adding files to a tar file ->
<?php
require_once "Archive.php";
$dir = "../../mysql/data/blackStone/";
$files[0] = "";
$i = 0;
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false ) {
if( $file != "." && $file != ".." )
$files[$i++] = $dir.$file;
}
}
File_Archive::extract(
$files,
File_Archive::toArchive(
'check.tar',
File_Archive::toOutput()
)
);
?>

You can call out from PHP into .NET assemblies. If you don't mind that, then you could use DotNetZip - it's reliable and totally non-erratic.
Sample code:
<?php
try
{
$fname = "zip-generated-from-php-" . date('Y-m-d-His') . ".zip";
$zipOutput = "c:\\temp\\" . $fname;
# Use COM interop to get to Ionic Zip. (Windows only)
$zip = new COM("Ionic.Zip.ZipFile");
$zip->Name = $zipOutput;
$dirToZip= "c:\\temp\\psh";
# Encryption: 3=AES256, 2=AES128, 1=PKZIP, 0=None.
$zip->Encryption = 3;
$zip->Password = "AES-Encryption-Is-Secure";
$zip->AddDirectory($dirToZip);
$zip->Save();
$zip->Dispose();
if (file_exists($zipOutput))
{
header('Cache-Control: no-cache, must-revalidate');
header('Content-Type: application/x-zip');
header('Content-Disposition: attachment; filename=' . $fname);
header('Content-Length: ' . filesize($zipOutput));
readfile($zipOutput);
unlink($zipOutput);
}
else
{

echo ' <head>';
echo ' <title>Calling DotNetZip from PHP through COM</title>';

}
}
catch (Exception $e)
{

echo '<p>The file was not successfully generated.</p>';
echo '<p>Caught exception: ', $e->getMessage(), '</p>', "\n";
echo '<pre>';
echo $e->getTraceAsString(), "\n";
echo '</pre>';
echo '</body>';
echo '</html>';
}
?>
