What are some common challenges when trying to display BLOB data in HTML using PHP?

One common challenge when trying to display BLOB data in HTML using PHP is that BLOB data needs to be converted to a format that can be displayed in a browser, such as an image or a file download link. To solve this, you can use PHP functions like base64_encode() to convert the BLOB data to a base64 encoded string, which can then be embedded in an HTML image tag or used to create a download link. 

// Assuming $blobData contains the BLOB data fetched from the database
$encodedData = base64_encode($blobData);
$imageSrc = 'data:image/jpeg;base64,' . $encodedData;

// Display the image in HTML
echo '<img src="' . $imageSrc . '" alt="BLOB Image">';
