What are the potential pitfalls of using variables like $handle in a loop to display images in PHP?

Using variables like $handle in a loop to display images in PHP can lead to conflicts and unexpected behavior, especially if the variable is not properly reset or scoped within each iteration of the loop. To avoid this, it's recommended to use a unique variable for each iteration of the loop to prevent any conflicts. 

// Example of using unique variables in a loop to display images
$images = ['image1.jpg', 'image2.jpg', 'image3.jpg'];

foreach ($images as $index => $image) {
    $handle = 'image_' . $index;
    echo "<img src='$image' alt='Image' name='$handle'>";
}
