Read the forum rules, especially the parts about asking proper questions and formatting code.

This is really an html question, is it not?

All that code, and your question boils down to this section:

echo "<div style=\"float:left;\">";
    echo $mcode."<br>";
    echo $barcode."<br>";
    echo "</div>";

See those

tags? You know what they do, don't you? If you take those out, what do you think will happen? Try this perhaps?

@gizmola. After i delete the <br> tags, it still the same. Would you mind if i post the full code so that you can run and test it. But this site can approve it or not because of the forum rules.

The reason why I pointed you to the forum guidelines was to a) make you use code tags and b) see an honest debugging attempt from you.

This "Here's a wall of code I copied and pasted from the Internet, now fix it for me" doesn't work. He can help you with specific issues, but we aren't going to do your job.

You've posted a screen shot. Have you also looked at it? You keep increasing the left margin, which will obviously defeat any alignment attempts. If you look at the page source (or just the scroll bar of your browser), you'll also see that the calculated width of a single image is gigantic. No screen is big enough to display those images next to each other.

Again, those are basic debugging steps which everybody can do. Yet they make a big difference, because they show that you actually care about the problem, and they allow us to have a proper discussion.
