function imageResize($width, $height, $target) {
//takes the larger size of the width and height and applies the
formula accordingly…this is so this script will work
dynamically with any size image
if ($width > $height) {
$percentage = ($target / $width);
} else {
$percentage = ($target / $height);
}
//gets the new value and applies the percentage, then rounds the value
$width = round($width * $percentage);
$height = round($height * $percentage);
//returns the new sizes in html image tag format…this is so you
can plug this function inside an image tag and just get the
return “width=\”$width\” height=\”$height\”";
