PHP resize image to fit within a certain area

Question

I have an image file that is stored within the variable $image I want to resize this image so it would fit within an area of 380px by 380px (so which means that the tallest side of the image must be 380px on the other side smaller than 380px). Has anyone a suggestion on how to do this?

Thanks

Are you trying to change the image permanently, or just display it at a particular size? — Brian Warshaw, Aug 13 '14 at 12:31

here is what I use to keep it under 800x600

$orig_image = imagecreatefromjpeg($file['tmp_name']);
list($width,$height) = getimagesize($file['tmp_name']);
if(max($width,$height) > 800){
  $scale = 800/max($width,$height);
  $new_width = floor($width*$scale);
  $new_height = floor($height*$scale);
  $save_image = imagecreatetruecolor($new_width,$new_height);
  imagecopyresampled($save_image,$orig_image,0,0,0,0,$new_width,$new_height,$width,$height);
  imagejpeg($save_image,self::$FILE_DIRECTORY."$year_month/$fileId.jpg");
  $orig_image = $save_image;
  $width = $new_width;
  $height = $new_height;
}

hopefully you can extrapolate a solution off that.. also not that my $file variable is coming from an uploaded file in the $_FILE array.

also don't worry about the last three variables (i also create thumbnail images and that's what those are for) — dano, Aug 13 '14 at 12:42
