archives and the files inside them.

PHP 4
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.

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.

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.
