What best practices are recommended by forum users for handling image scaling and file copying in PHP?

When handling image scaling in PHP, it is important to use a library like GD or Imagick to resize images while maintaining aspect ratio. For file copying, it is recommended to use functions like `copy()` or `move_uploaded_file()` to ensure proper file transfer without data loss. 

// Image Scaling using GD Library
$source = 'image.jpg';
$destination = 'scaled_image.jpg';

list($width, $height) = getimagesize($source);
$newWidth = 100; // desired width
$newHeight = ($height / $width) * $newWidth;

$src = imagecreatefromjpeg($source);
$dst = imagecreatetruecolor($newWidth, $newHeight);
imagecopyresampled($dst, $src, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);

imagejpeg($dst, $destination);
imagedestroy($src);
imagedestroy($dst);

// File Copying
$sourceFile = 'file.txt';
$destinationFile = 'copied_file.txt';

if (copy($sourceFile, $destinationFile)) {
    echo "File copied successfully.";
} else {
    echo "Error copying file.";
}
