It simple to use Simple image
<?php
include('src/abeautifulsite/SimpleImage.php');
try {
$img = new abeautifulsite\SimpleImage('/*image name*/');
$img->resize(320, 200)->save('/*name of resize image*/');resize image and save resized image
} catch(Exception $e) {
echo 'Error: ' . $e->getMessage();
}

Answer 2

Oleh is correct, if you're struggling with image resizing it's best to use a library to handle all the edge cases and gotchas.
Here's how to do it with SimpleImage 2.x:
$image = new \abeautifulsite\SimpleImage('image.jpg');
$image->resize(320, 200)->save('result.jpg');
And SimpleImage 3.x:
$image = new \claviska\SimpleImage('image.jpg');
$image->resize(320, 200)->toFile('output.jpg');
The SimpleImage library can be installed with Composer:
composer require claviska/simpleimage
Or downloaded from GitHub and included manually.
