I've stored an image file on my local drive and the path to that image in my datab开发者_如何学编程ase. How can I retrieve the image for displaying it in PHP?

---

Select the data from the DB into variables ($path and $image_name).
echo it (in your view file):

echo "<img src='{$path}/{$image_name}' />";

If you're trying to write a script to serve the image up on demand, you'll want to take a look at the readfile() function: http://php.net/manual/en/function.readfile.php

You should store the content-type that was sent when the file was originally uploaded too. Keep this with the other information you've saved about the image in the database.
