Zip File Functions

简介

This extension enables you to transparently read or write ZIP compressed archives and the files inside them.

需求

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.

安装

PHP 4

Note: Zip support before PHP 4.1.0 is experimental.

Warning

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.

Installation via PECL

安装此 PECL 扩展库的信息可在手册中标题为 PECL 扩展库安装的一章中找到。更多信息如新版本，下载，源文件，维护者信息以及更新日志等可以在这里找到： » http://pecl.php.net/package/zip.

可以从 » PHP 下载页面或者 » http://snaps.php.net/ 下载此 PECL 扩展的 DLL 文件。

在 PHP 4 中本 DLL 位于 PHP Windows 执行包中的 extensions/ 目录下。

运行时配置

本扩展模块在 php.ini 中未定义任何配置选项。

资源类型

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.

预定义常量

以下常量由本扩展模块定义，因此只有在本扩展模块被编译到 PHP 中，或者在运行时被动态加载后才有效。

ZipArchive uses class constants. There is three types of constants, Flags (FL_) errors (ER_) or mode (no prefix).

ZIPARCHIVE::CREATE (integer): Create the archive if it does not exist.
ZIPARCHIVE::OVERWRITE (integer): Always start a new archive, this mode will overwrite the file if it already exists.
ZIPARCHIVE::EXCL (integer): Error if archive already exists.
ZIPARCHIVE::CHECKCONS (integer): Perform additional consistency checks on the archive, and error if they fail.
ZIPARCHIVE::FL_NOCASE (integer): Ignore case on name lookup
ZIPARCHIVE::FL_NODIR (integer): Ignore directory component

范例

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);

}
