Is it possible to rotate an image in PHP based on a given value, such as in the example with the voltage scale?

To rotate an image in PHP based on a given value, such as in the example with the voltage scale, you can use the `imagerotate` function provided by the GD library. You would need to calculate the rotation angle based on the given value and then apply the rotation to the image using the `imagerotate` function.

// Load the image
$image = imagecreatefromjpeg('image.jpg');

// Calculate the rotation angle based on the given value
$angle = $voltage * 10; // Adjust the factor as needed

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

// Output the rotated image
header('Content-Type: image/jpeg');
imagejpeg($rotated_image);

// Free up memory
imagedestroy($image);
imagedestroy($rotated_image);
