Display MySQL image data in PHP page - php

Question

I am currently looking to display an image on my website using PHP. The image data is in MySQL, and I know how to display data from MySQL, but I can't figure out how to display images using insertname.png type data.
My code is currently this: (In pet_url, it basically states dogpuppyrare.png, which is a png inside my public_html inside my file manager on my hosting website.
<?php
$servername = "localhost";
$username = "dbuser";
$password = "dbpass";
$dbname = "db name";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT pet_url FROM user_pets";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo $row["pet_url"]. "<br>";
}
} else {
echo "0 results";
}
$conn->close();
?>

Answer 1

The fact the field is labelled ['pet_url'], I'm making the assumption that the data in this key is a URL, so just display the src using the HTML img tag.
if ($result->num_rows > 0) {
//output data of each row
while ($row = $result->fetch_assoc()) {
echo '<img src="' . $row["pet_url"] . '" alt="my pet image"/>"<br>"';
}
}
You can read more about image tags at w3schools:

Convert this line:
echo $row["pet_url"]. "<br>";
To this;
echo '<img src="'. $row["pet_url"] . '" alt="my pet image" /><br>';
