如何使用PHP从文件系统显示图像

Question

Okay, so I have a database that stores the name of an uploaded file in a column called filename.

I am trying to use PHP to show that file (stored in the file-system, not database) by taking the filename as stored in the database and concatenating it onto the HTML tag, like so:

$stmt = $db->dbh->query("SELECT id, filename FROM images");
$stmt->setFetchMode(PDO::FETCH_BOTH);

$path = '';

while ($row = $stmt->fetch()) {
    $path = 'i/' . $row['filename'];
    echo "<img src=" . $path . "/>";
}

However, it's not showing anything. What am I doing wrong, or what is a better way to accomplish this?

Answer 1

You are missing quotes around the image file name. Try this:

  echo '<img src="' . htmlspecialchars($path) . '"/>";
