What potential issues or errors could arise when trying to create a zip file using PHP?

One potential issue that could arise when creating a zip file using PHP is running out of memory if you are trying to compress a large number of files or very large files. To solve this issue, you can increase the memory limit in your PHP configuration or split the files into smaller batches before compressing them. 

// Increase memory limit
ini_set('memory_limit', '256M');

// Create a zip file
$zip = new ZipArchive();
$zipFileName = 'example.zip';

if ($zip->open($zipFileName, ZipArchive::CREATE) === TRUE) {
    // Add files to the zip archive
    $zip->addFile('file1.txt');
    $zip->addFile('file2.txt');
    
    // Close the zip archive
    $zip->close();
    echo 'Zip file created successfully';
} else {
    echo 'Failed to create zip file';
}
