Try this:
function Resize_Image($FilePath, $new_w){
$File = fopen($FilePath, "r");
$FileContents = fread($File, filesize($FilePath));
$src = imagecreatefromstring($FileContents);
$width = imagesx($src);
// Shrink the image to the maximum width
// Maintaining aspect ratio
if($width > $new_w){
$height = imagesy($src);
$aspect_ratio = $height/$width;
$new_h = abs($new_w * $aspect_ratio);
$img = imagecreatetruecolor($new_w,$new_h);
imagecopyresized($img,$src,0,0,0,0,$new_w,$new_h,$width,$height);
ob_start();
imagejpeg($img);
$FileContents = ob_get_contents();
ob_end_clean();
imagedestroy($img);
}
return $FileContents;
}
you can then either save the filecontents as an image, or place it in a
database.
