This extension enables you to transparently read or write ZIP compressed archives and the files inside them.
The bundled PHP 4 version requires » ZZIPlib, by Guido Draheim, version 0.10.6 or later
This extension uses the functions of » zlib by Jean-loup Gailly and Mark Adler.
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.
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 users need to enable php_zip.dll inside of php.ini in order to use these functions.

Вы можете скачать DLL этого расширения PECL со страницы » PHP Downloads или » http://snaps.php.net/.
В PHP 4 этот DLL находится в директории extensions/ внутри директории бинарного дистрибутива PHP для Windows.
Данное расширение не определяет никакие директивы конфигурации в php.ini.
There are two resource types used in the Zip module. The first one is the Zip directory for the Zip archive, the second Zip Entry for the archive entries.
Перечисленные ниже константы определены данным расширением и могут быть доступны только в том случае, если PHP был собран с поддержкой этого расширения или же в том случае, если данное расширение подгружается во время выполнения.
ZipArchive uses class constants. There is three types of constants, Flags (FL_) errors (ER_) or mode (no prefix).
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: " . $za->status . "\n";
echo "statusSys: " . $za->statusSys . "\n";
echo "filename: " . $za->filename . "\n";
echo "comment: " . $za->comment . "\n";
for ($i=0; $i<$za->numFiles;$i++) {
echo "index: $i\n";
print_r($za->statIndex($i));
}
echo "numFile:" . $za->numFiles . "\n";
?>
Example#3 Zip stream wrapper, read an OpenOffice meta info
<?php
$reader = new XMLReader();
$reader->open('zip://' . dirname(__FILE__) . '/test.odt#meta.xml');
$odt_meta = array();
while ($reader->read()) {
if ($reader->nodeType == XMLREADER::ELEMENT) {
$elm = $reader->name;
} else {
if ($reader->nodeType == XMLREADER::END_ELEMENT && $reader->name == 'office:meta') {
break;
}
if (!trim($reader->value)) {
continue;
}
$odt_meta[$elm] = $reader->value;
}
}
print_r($odt_meta);
?>
This example uses the old API (PHP 4), it opens a ZIP file archive, reads each file in the archive and prints out its contents. The test2.zip archive used in this example is one of the test archives in the ZZIPlib source distribution.
Example#4 Zip Usage Example
<?php
$zip = zip_open("/tmp/test2.zip");
if ($zip) {
while ($zip_entry = zip_read($zip)) {
echo "Name: " . zip_entry_name($zip_entry) . "\n";
echo "Actual Filesize: " . zip_entry_filesize($zip_entry) . "\n";
echo "Compressed Size: " . zip_entry_compressedsize($zip_entry) . "\n";
echo "Compression Method: " . zip_entry_compressionmethod($zip_entry) . "\n";
if (zip_entry_open($zip, $zip_entry, "r")) {
echo "File Contents:\n";
$buf = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
echo "$buf\n";
zip_entry_close($zip_entry);
}
echo "\n";
}
zip_close($zip);
}
?>
