How can the presence of HTML code in the output affect the display of images fetched from a MySQL database in PHP?

When HTML code is present in the output of a PHP script, it can interfere with the display of images fetched from a MySQL database. To solve this issue, it is important to properly encode the image data before outputting it to the browser. This can be done using base64 encoding, which converts the binary image data into a string format that can be safely embedded in HTML. 

<?php
// Fetch image data from MySQL database
$imageData = $row['image_data'];

// Encode the image data using base64
$encodedImageData = base64_encode($imageData);

// Output the image in an HTML img tag
echo '<img src="data:image/jpeg;base64,' . $encodedImageData . '" alt="Image">';
?>
