What role do file permissions play in the successful creation of a zip file in PHP?

File permissions play a crucial role in the successful creation of a zip file in PHP. If the file permissions are not set correctly, PHP may not have the necessary permissions to write the zip file to the specified directory. To ensure successful creation of a zip file, make sure that the directory where the zip file will be created has the appropriate write permissions for the PHP process. 

// Set appropriate file permissions for the directory where the zip file will be created
chmod('/path/to/directory', 0777);

// Create a new ZipArchive object
$zip = new ZipArchive();

// Specify the path and name of the zip file to create
$zipFile = '/path/to/directory/zipfile.zip';

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