Zip File Functions
Введение
This extension enables you to transparently read or write ZIP compressed archives and the files inside them.
Требования
PHP 4
The bundled PHP 4 version requires » ZZIPlib, by Guido Draheim, version 0.10.6 or later
PHP 5.2.0 or later
This extension uses the functions of » zlib by Jean-loup Gailly and Mark Adler.
Установка
PHP 4
Note: Zip support before PHP 4.1.0 is experimental.
Because the PHP 4 zip extension is unmaintained we recommend that the PECL extension is used rather than the bundled one.
Linux systems
In order to use these functions you must compile PHP with zip support by using the --with-zip[=DIR] configure option, where [DIR] is the prefix of the » ZZIPlib library install.
Windows
Windows users need to enable php_zip.dll inside of php.ini in order to use these functions.
PHP 5.2.0 and later
Linux systems
In order to use these functions you must compile PHP with zip support by using the --enable-zip configure option.
Windows
Windows users need to enable php_zip.dll inside of php.ini in order to use these functions.

Примеры
Example#1 Create a Zip archive
<?php
$zip = new ZipArchive();
$filename = "./test112.zip";
if ($zip->open($filename, ZIPARCHIVE::CREATE)!==TRUE) {
exit("cannot open <$filename>\n");
}
$zip->addFromString("testfilephp.txt" . time(), "#1 This is a test string added as testfilephp.txt.\n");
$zip->addFromString("testfilephp2.txt" . time(), "#2 This is a test string added as testfilephp2.txt.\n");
$zip->addFile($thisdir . "/too.php","/testfromfile.php");
echo "numfiles: " . $zip->numFiles . "\n";
echo "status:" . $zip->status . "\n";
$zip->close();
?>
Example#2 Dump the archive details and listing
<?php
$za = new ZipArchive();
$za->open('test_with_comment.zip');
print_r($za);
var_dump($za);
echo "numFiles: " . $za->numFiles . "\n";
echo "status: " . $
