How can the quality loss in images processed with PHP functions be minimized?

When processing images with PHP functions, the quality loss can be minimized by adjusting the compression settings. By setting the compression level to a higher value, the image quality can be maintained at a satisfactory level while reducing the file size. This can be achieved using functions like `imagejpeg()` with the `quality` parameter.

// Load the original image
$original_image = imagecreatefromjpeg('original.jpg');

// Create a new image with adjusted compression quality
imagejpeg($original_image, 'compressed.jpg', 90); // 90 is the quality level (0-100)

// Free up memory
imagedestroy($original_image);
