What are some common pitfalls when working with EXIF information in PHP?

One common pitfall when working with EXIF information in PHP is not properly handling errors when reading or writing EXIF data. To avoid this issue, it is important to check for errors and handle them appropriately in your code. 

// Check for errors when reading EXIF data
$exif = exif_read_data('image.jpg', 'IFD0', true);
if ($exif === false) {
    echo "Error reading EXIF data";
} else {
    // Process EXIF data
}

// Check for errors when writing EXIF data
$exif_data = ['Make' => 'Canon', 'Model' => 'EOS 5D Mark IV'];
$success = exif_write_data('image.jpg', $exif_data);
if (!$success) {
    echo "Error writing EXIF data";
} else {
    echo "EXIF data written successfully";
}
