How to crop an image in PHP?

Question

PHP

Imagine that a user uploads some kind of image to the site, and I need to crop this image to a 4:3 ratio. How to do it? Or let's let's give the image its own height (eg 765 and 465).

Answer 1

Here is a great handy thing for such things
https://github.com/Intervention/image
The only thing that it does not normally do (although there is such an option) is that it does not position the text normally on pictures.
For this, this is great https://github.com/stil/gd-text
Here, together with them, you can already do anything with minimal effort.

Answer 2

function createImage($filename,$w,$h,$endName){
$name=$filename;
$createImage = imagecreatetruecolor($w, $h);
$transparent = imagecolorallocatealpha($createImage, 0, 0, 0, 127);
imagefill($createImage, 0, 0, $transparent);
imagesavealpha($createImage, true);
$image = imagecreatefrompng($name);
imagecopyresampled($createImage, $image, 0, 0, 0, 0, $w, $h, imagesx($image), imagesy($image));
$endImage=imagepng($createImage, $endName, 9);
return $endImage;
}

createImage('входное изображение',высота, ширина,'изображение на выходе');

used this script for png
