Are there best practices for handling file paths and database queries in PHP for image retrieval?

When retrieving images from a database in PHP, it's important to properly handle file paths to ensure the images are displayed correctly. One best practice is to store the file paths in the database as relative paths rather than absolute paths. This allows for easier migration of the application to different servers without having to update all the file paths in the database.

// Assuming $row is the fetched database row containing the image file path
$imagePath = 'uploads/' . $row['image_filename']; // Assuming images are stored in a folder named 'uploads'

// Display the image using the $imagePath variable
echo '<img src="' . $imagePath . '" alt="Image">';
