What potential issue is the user facing when trying to create a zip file without the main folder?

The potential issue the user is facing when trying to create a zip file without the main folder is that the files are being added to the zip archive with their full directory paths included. To solve this issue, the user can iterate through the files in the main folder and add them to the zip archive without including the main folder name in the file paths. 

$mainFolder = 'path/to/main/folder';
$zipFile = 'path/to/output.zip';

$zip = new ZipArchive;
if ($zip->open($zipFile, ZipArchive::CREATE) === TRUE) {
    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($mainFolder), RecursiveIteratorIterator::SELF_FIRST);
    foreach ($files as $file) {
        if ($file->isFile()) {
            $filePath = $file->getRealPath();
            $relativePath = substr($filePath, strlen($mainFolder) + 1);
            $zip->addFile($filePath, $relativePath);
        }
    }
    $zip->close();
    echo 'Zip file created successfully.';
} else {
    echo 'Failed to create zip file.';
}
