What role does Photoshop play in storing metadata within image files and how does this impact the ability to extract that metadata using PHP?

Photoshop stores metadata within image files using XMP (Extensible Metadata Platform) format. This metadata includes information such as camera settings, date taken, and copyright details. To extract this metadata using PHP, you can use the `exif_read_data()` function to read the XMP data from the image file. 

// Specify the path to the image file
$image_path = 'image.jpg';

// Read the XMP metadata from the image file
$exif_data = exif_read_data($image_path, 'XMP');

// Output the metadata
print_r($exif_data);
