php ZipArchive - 仅添加不是父文件夹的文件

Question

I am creating a zip archive in php and want to add some pdf files available in my pdfs_lib folder.I have successfully created the archive but there is a problem that inside the created zip archive, files get added into pdfs_lib folder, which is not what i want.

I want to add pdf files present in pdfs_lib folder directly into the archive instead of adding those files inside pdfs_lib folder in my created zip archive.

What i have tried is:

    // Create Zip File
    $zip = new ZipArchive;
    $res = $zip->open("pdfs_lib/my_zip_archive.zip", ZipArchive::CREATE);
    if ($res === TRUE)
    {
        // Add pdf file to zip archive
        $zip->addFile("pdfs_lib/pdf_file_1.pdf");
        $zip->addFile("pdfs_lib/pdf_file_2.pdf");

        $zip->close();
        echo 'ok';
    } else {
        echo 'failed';
    }

This code creates the zip archive successfully but whwen i unzip the archive it creates a pdfs_lib folder and unzip all files inside this newly created folder.

Any suggestion on how to create a zip archive without add pdf_lib folder in it.

Answer 1

Change the addFile calls to:

$zip->addFile("pdfs_lib/pdf_file_1.pdf", "pdf_file_1.pdf");

The second parameter is the 'localname', the name used in the zipfile itself. If you leave out the folderpath there, it will be added to the root in the zipfile.
