What are best practices for debugging file transfer and extraction issues in PHP scripts?

Issue: When encountering file transfer and extraction issues in PHP scripts, it is important to first check for any errors or warnings that may be thrown during the process. This can be done by enabling error reporting and checking the return values of file transfer and extraction functions. Additionally, verifying file paths, permissions, and file formats can help identify potential issues. 

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Example of transferring a file from one location to another
$sourceFile = '/path/to/source/file.txt';
$destinationFile = '/path/to/destination/file.txt';

if (copy($sourceFile, $destinationFile)) {
    echo 'File transferred successfully.';
} else {
    echo 'Error transferring file.';
}

// Example of extracting a ZIP archive
$zipFile = '/path/to/archive.zip';
$extractPath = '/path/to/extracted/files/';

$zip = new ZipArchive;
if ($zip->open($zipFile) === TRUE) {
    $zip->extractTo($extractPath);
    $zip->close();
    echo 'Archive extracted successfully.';
} else {
    echo 'Error extracting archive.';
}
