What are the advantages of using PNG over GIF in terms of image compression and efficiency in PHP?

When comparing PNG and GIF formats in terms of image compression and efficiency, PNG typically offers better compression ratios and supports more colors than GIF. This can result in smaller file sizes for PNG images compared to GIF images, making them more efficient for web use. 

// Example code demonstrating the use of PNG over GIF for image compression in PHP

// Create a new PNG image
$image = imagecreatefrompng('image.png');

// Save the PNG image with compression level 9 (highest)
imagepng($image, 'compressed_image.png', 9);

// Free up memory
imagedestroy($image);
