Hi there. We rather prefer questions that have been researched here, so I am downvoting. How to rotate an image using `convert` is in the IM manual. — halfer, May 14 '15 at 07:00

With Imagick, use rotateImage

<?php
$image = new Imagick("source.kpg");
$image->rotateImage ( 'white', 90.0 );

You can do this with ImageMagick. The following command will rotate the image:

convert original_file.jpg -rotate 90 new_file.jpg

Use the PHP function imagerotate
http://php.net/manual/en/function.imagerotate.php

Example:

<?php
// File and rotation
$filename = 'test.jpg';
$degrees = 180;

// Content type
header('Content-type: image/jpeg');

// Load
$source = imagecreatefromjpeg($filename);

// Rotate
$rotate = imagerotate($source, $degrees, 0);

// Output
imagejpeg($rotate);

// Free the memory
imagedestroy($source);
imagedestroy($rotate);
?>
