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.
Bemærk:
Zip support before PHP 4.1.0 is experimental.
Advarsel |
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.

Denne udvidelse har intet konfigurations-direktiv defineret i 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.
Konstanterne nedenunder er defineret af denne udvidelse, og
vil kun være tilgængelige når denne udvidelse enten er blevet
kompileret ind i PHP eller dynamisk indsat under runtime.
ZipArchive uses class constants. There is three types of constants,
Flags (FL_) errors (ER_) or mode (no prefix).
- ZIPARCHIVE::CREATE

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