//$w_o ? h_o – Width and height of output image

list($w_i, $h_i, $type) = getimagesize($image); // Return the size and image type (number)

//calculating 16:9 ratio
$w_o = $w_i;
$h_o = 9 * $w_o / 16;

//if output height is longer then width
if ($h_i < $h_o) {
$h_o = $h_i;
$w_o = 16 * $h_o / 9;
}

$x_o = $w_i – $w_o;
$y_o = $h_i – $h_o;

$types = array(“jpg”, “gif”, “jpeg”, “png”); // Array with image types
$ext = $types[$type]; // If you know image type, “code” of image type, get type name

echo ‘Incorrect image’; // Showing an error, if the image type is unsupported
return false;
}
if ($x_o + $w_o > $w_i) $w_o = $w_i – $x_o; // If width of output image is bigger then input image (considering x_o), reduce it
if ($y_o + $h_o > $h_i) $h_o = $h_i – $y_o; // If height of output image is bigger then input image (considering y_o), reduce it
$img_o = imagecreatetruecolor($w_o, $h_o); // Creating descriptor for input image
imagecopy($img_o, $img_i, 0, 0, $x_o/2, $y_o/2, $w_o, $h_o); // Move part of image from input to output
$func = ‘image’.$ext; // Function that allows to save the result
