Are there any best practices for handling image metadata in PHP applications?

When handling image metadata in PHP applications, it is important to sanitize user input to prevent any potential security vulnerabilities such as injection attacks. One best practice is to use PHP's built-in functions for handling image metadata, such as exif_read_data(), to extract and manipulate metadata safely. 

// Example of reading image metadata using exif_read_data()
$imagePath = 'path/to/image.jpg';
$metadata = exif_read_data($imagePath);

// Output all metadata
print_r($metadata);
