How can PHP developers efficiently handle image manipulation and dynamic content generation in their scripts?

To efficiently handle image manipulation and dynamic content generation in PHP scripts, developers can utilize libraries like GD or Imagick for image processing tasks, and use caching mechanisms to store generated content to reduce server load and improve performance. 

// Example code snippet using GD library for image manipulation
$image = imagecreatefromjpeg('image.jpg'); // Load image
$new_image = imagecreatetruecolor(200, 200); // Create a new image with desired dimensions
imagecopyresampled($new_image, $image, 0, 0, 0, 0, 200, 200, imagesx($image), imagesy($image)); // Resize image
header('Content-Type: image/jpeg');
imagejpeg($new_image); // Output modified image
imagedestroy($image); // Clean up resources
imagedestroy($new_image);
