How can PHP developers effectively debug issues related to file manipulation functions like "copy"?

When debugging issues related to file manipulation functions like "copy" in PHP, developers can effectively use error handling techniques such as checking for errors returned by the function or using the "file_exists" function to verify the existence of the source file before copying. Additionally, developers can also use tools like Xdebug for more advanced debugging capabilities. 

$sourceFile = 'source.txt';
$destinationFile = 'destination.txt';

if (file_exists($sourceFile)) {
    if (copy($sourceFile, $destinationFile)) {
        echo 'File copied successfully.';
    } else {
        echo 'Error copying file.';
    }
} else {
    echo 'Source file does not exist.';
}
