How can the use of foreach loops in PHP impact the display of images retrieved from a MySQL database?

When using foreach loops in PHP to display images retrieved from a MySQL database, it is important to ensure that the image data is properly fetched and displayed within the loop. One common issue is not properly encoding or decoding the image data, resulting in broken or incomplete images being displayed. To solve this, make sure to use appropriate encoding functions like base64_encode() and base64_decode() to handle the image data before displaying it. 

<?php
// Assuming $images is an array containing image data fetched from MySQL
foreach ($images as $image) {
    // Decode the image data using base64_decode() before displaying
    $decoded_image = base64_decode($image['image_data']);
    echo '<img src="data:image/jpeg;base64,' . base64_encode($decoded_image) . '" alt="Image">';
}
?>
