How to resize jpg file by PHP?

Question

It's now 925*1139,I want to change it to 90*110.

Solution 1

try the imagecopyresampled PHP function or the imagecopyresized function from the GD library.

Solution 2

Basically using GD is pretty easy once you know what to do.

$uploadedfile = $_FILES['file']['tmp_name']; 
$src = imagecreatefromjpeg($uploadedfile);        
list($width, $height) = getimagesize($uploadedfile); 

$tmp = imagecreatetruecolor(800, 600); 

$filename = '/path/to/images/' . $_FILES['file']['name'];

imagecopyresampled($tmp, $src, 0, 0, 0, 0, 800, 600, $width, $height); 
imagejpeg($tmp, $filename, 100);

Again check the blog for details.

The first one, as its name indicates, resampled while resizing for a better result. The second one only resize.
