What are the best practices for handling image creation and display in PHP scripts?

When handling image creation and display in PHP scripts, it is important to ensure that the images are properly sanitized to prevent security vulnerabilities such as injection attacks. It is recommended to use functions like imagecreatefromjpeg(), imagecreatefrompng(), or imagecreatefromgif() to create images from file uploads or external sources. Additionally, always validate user input and use proper error handling to prevent any potential issues with image manipulation.

// Example of handling image creation and display in PHP
// Create a new image from a JPEG file
$image = imagecreatefromjpeg('example.jpg');

// Display the image on the webpage
header('Content-Type: image/jpeg');
imagejpeg($image);
imagedestroy($image);
