Answer 1

Here you are missing '.

I would do it like this:

 echo '<tr><td><img src="images/' . $row['picture'] . '" alt="' . $row['username'] . '" /></td>';

There are several other ways to do this, but I would not recommend using short tags or inserting variables into ever strings . It doesn't matter if it's double quotation marks, break the line and concatenate. It is much easier on the eyes and makes for cleaner code.

Answer 5

$row ['picture']

echo '<tr><td><img src="images/' . $row['picture'] . '" alt="' . $row['username'] . '" /></td>';

, :

echo "<tr><td><img src='images/{$row['picture']}' alt='{$row['username']}'/></td>";

If you have double quotes, you can include array values ​​in a string if they are enclosed in {}. Of course, you need to change the double quotes in the html elements to single ones or to avoid them.
