How can the issue of "imagecreatefromjpeg() reports unrecoverable error: Not a JPEG file" be addressed in PHP?

The issue of "imagecreatefromjpeg() reports unrecoverable error: Not a JPEG file" can be addressed by checking if the file is a valid JPEG file before attempting to create an image from it. This can be done by using the getimagesize() function to determine the file type. 

$filename = 'image.jpg';

// Check if the file is a valid JPEG file
$image_info = getimagesize($filename);
if ($image_info !== false && $image_info['mime'] == 'image/jpeg') {
    $image = imagecreatefromjpeg($filename);
    // Further processing of the image
} else {
    echo "Error: Not a valid JPEG file";
}
