How can PHP developers ensure consistency and performance when working with graphic data in PHP applications?

To ensure consistency and performance when working with graphic data in PHP applications, developers can utilize libraries like GD or Imagick for image processing tasks. These libraries provide efficient functions for manipulating images, resizing, cropping, and applying filters while maintaining consistency in output quality. Additionally, developers should optimize their code by caching images, using appropriate file formats, and minimizing unnecessary image processing operations. 

// Example code using GD library to resize an image
$image = imagecreatefromjpeg('input.jpg');
$width = imagesx($image);
$height = imagesy($image);
$newWidth = 200;
$newHeight = ($height / $width) * $newWidth;
$newImage = imagecreatetruecolor($newWidth, $newHeight);
imagecopyresampled($newImage, $image, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);
imagejpeg($newImage, 'output.jpg');
imagedestroy($image);
imagedestroy($newImage);
