What is the function of the PHP code www.php.net/copy in relation to file operations?

The PHP function `copy()` is used to copy a file from one location to another. This function takes two parameters: the source file path and the destination file path. It returns `true` if the copy operation is successful, and `false` otherwise.

$source = "path/to/source/file.txt";
$destination = "path/to/destination/file.txt";

if (copy($source, $destination)) {
    echo "File copied successfully!";
} else {
    echo "Failed to copy file.";
}
