PHP ZipArchive 删除文件名的第一个字符

Question

The code below successfully creates a zip file of a specified directory and all sub-directories. The problem I am having is that the end result removes the first character from each filename and folder-name within the root directory; this same behavior does not occur in the sub-directories.

<?php
    require('../config/config.php');

    $rootPath = $abs_path.'/includes/qrcodes/'; // SOURCE FOLDER TO ZIP
    $zipFilename = 'qr_images.zip';
    $zip = new ZipArchive();
    $zip->open($zipFilename, ZipArchive::CREATE | ZipArchive::OVERWRITE);

    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($rootPath), RecursiveIteratorIterator::LEAVES_ONLY);

    foreach ($files as $name => $file)
    {
        $filePath = $file->getRealPath();
        $relativePath = substr($filePath, strlen($rootPath) + 1);

        if (!$file->isDir())
        {
            $zip->addFile($filePath, $relativePath);

        }else {

            if($relativePath !== false)
                $zip->addEmptyDir($relativePath);
        }
    }

    $zip->close(); 
?>

Currently the resulting zip file includes:

• adios (folder)
  • radio_1.png
  • radio_2.png
• nfosys (folder)
  • infosys_1.png
• ehicles (folder)
  • vehicle_1.png
  • vehicle_2.png

The folders should be named "radios", "infosys", and "vehicles".

The code appears to have been designed for a $rootpath variable without a trailing backslash. If you'd change it $rootPath = $abs_path.'/includes/qrcodes'; the +1 at the substr would be required. Otherwise the relative path would start with a '/'.
