Create New ZIP Archive
This section provides a tutorial example on how to create a new ZIP archive and add files into the archive using the ZipArchive class.
The best way to create a new ZIP archive is to use the "ZipArchive::CREATE" flag in the $zip->open() method. For example, the following code will create a new empty ZIP archive, if '/tmp/test.zip' does not exist. If '/tmp/test.zip' exists, it will be open to add new entries or extract entries. It fails only if '/tmp/test.zip' exists and is not a ZIP file.
$zip = new ZipArchive;
$zip->open('/tmp/test.zip',ZipArchive::CREATE);
Here is an example script that create a new ZIP archive and adds some files into the archive.
<?php
# zip-create-new.php
#- Copyright 2009 (c) HerongYang.com. All Rights Reserved.
$zip = new ZipArchive;
echo "Creating test.zip:\n";
$rc = $zip->open('/tmp/test.zip',ZipArchive::CREATE);
if ($rc === TRUE) {
echo " test.zip opened\n";
$file = 'dot.gif';
if ($zip->addFile($file) === TRUE) {
echo " $file added\n";
} else {
echo " Failed to add $file.\n";
}
$file = 'zip-create-new.php';
if ($zip->addFile($file) === TRUE) {
echo " $file added\n";
} else {
echo " Failed to add $file.\n";
}
$file = 'junk.jnk';
if ($zip->addFile($file) === TRUE) {
echo " $file added\n";
} else {
echo " Failed to add $file.\n";
}
$zip->close();
} else {
echo " Failed to create test.zip with error: $rc\n";
}
?>
Let's try it:
herong$ php zip-create-new.php
Creating test.zip:
test.zip opened
dot.gif added
zip-create-new.php added
Failed to add junk.jnk.
herong$ unzip -l /tmp/test.zip
Archive: /tmp/test.zip
