What potential issues can arise when using the exif_read_data function in PHP, as mentioned in the forum thread?

The potential issue that can arise when using the exif_read_data function in PHP is that it may throw a warning or error if the image file does not contain EXIF data. To solve this issue, you can check if the exif data exists before trying to read it to avoid any errors. 

$exif_data = exif_read_data($image_path, 'EXIF');
if($exif_data !== false){
    // Process the exif data
    // Example: echo $exif_data['Make'];
} else {
    echo "No EXIF data found in the image.";
}
