Rotate Images with imagerotate()

<?php
$source = imagecreatefromjpeg('photo.jpg');
if ($source === false) { exit('Unable to load image.'); }
$background = imagecolorallocate($source, 255, 255, 255);
$rotated = imagerotate($source, 30, $background);
if ($rotated === false) { exit('Unable to rotate image.'); }

imagejpeg($rotated, 'rotated.jpg', 90);
?>

<?php
header ("Content-Type: image/jpeg");

$file_name='../images/top2.jpg'; // Image collected
$angle='180';    // Angle of rotation is set
$img_source = imagecreatefromjpeg($file_name); // Image created

$img_rotated = imagerotate($img_source, $angle, 0); // Rotate the image

imagejpeg($img_rotated); // Output Displayed
?>

imagerotate($source_image,$angle,$bg_color,$int_transparent)

Using background colour

<?php
header ("Content-Type: image/jpeg");
$file_name='../images/top2.jpg';
$angle='45'; // Angle of rotation in degree
$img_source = imagecreatefromjpeg($file_name);
$bg_color = ImageColorAllocate ($img_source, 4, 20, 204);
// Rotate
$img_rotated = ImageRotate($img_source, $angle, $bg_color, 0);
// Output Display 
imagejpeg($img_rotated);
?>
