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.
注意:
Zip support before PHP 4.1.0 is experimental.
警告 |
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.
In order to use these functions you must compile PHP with zip support

本扩展模块在 php.ini 中未定义任何配置选项。
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.
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).

例 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(); ?>
|
|
例 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"; ?>
|
|
例 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.
例 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);
} ?>
