Are functions like stat() and exif_read_data() suitable for extracting and changing file information like creation date, title, author, keywords, version, and comments?

Yes, functions like stat() and exif_read_data() are suitable for extracting file information such as creation date, title, author, keywords, version, and comments. However, these functions may not always be able to change this information directly. To modify file metadata like creation date, title, author, etc., you may need to use additional functions or libraries that support writing metadata to files. 

// Example of extracting file information using exif_read_data()
$exif = exif_read_data('image.jpg');
echo "Creation Date: " . $exif['DateTime'] . "\n";
echo "Title: " . $exif['Title'] . "\n";
echo "Author: " . $exif['Artist'] . "\n";

// Example of changing file creation date using touch()
$timestamp = strtotime('2022-01-01 12:00:00');
touch('image.jpg', $timestamp);
