Can PHP handle 24-bit PNG images with transparency effectively?

PHP can handle 24-bit PNG images with transparency effectively by using the `imagepng()` function with the `PNG_NO_FILTER` flag set. This flag prevents PHP from applying filters that can cause issues with transparency in 24-bit PNG images. By using this flag, you can ensure that the transparency in your images is preserved correctly. 

$source = imagecreatefrompng('image.png');
$destination = 'output.png';

imagealphablending($source, false);
imagesavealpha($source, true);

imagepng($source, $destination, 0, PNG_NO_FILTER);

imagedestroy($source);
