Zip File Functions
Zip
&reftitle.intro;
This module enables you to transparently read or write ZIP compressed
archives and the files inside them.
&reftitle.required;
PHP 4 Bundled
The initial version is bundled in PHP 4 and is available in PECL
as version 1.0, see
&url.pecl.package;zip. It can only read Zip Archives.
This version uses the functions of the ZZIPlib library by Guido Draheim.
You need ZZIPlib version >= 0.10.6.
PECL and PHP 5.2 or earlier
The newest version is bundled in PHP 5.2.0 or earlier and
available in PECL, as version 1.1.0 or earlier. It does not
require any external library. It can read and write Zip archives
when used with PHP 5.1 or ealier and can only read them when used
with PHP4.
&reference.zip.configure;
&reftitle.runtime;
&no.config;
&reftitle.resources;
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.

&reftitle.examples;
Create a Zip archive
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";
$zip->close();
?>
]]>
Dump the archive details and listing
open('test_with_comment.zip');
print_r($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";
?>
]]>
Zip stream wrapper, read an OpenOffice meta info
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.
