How can we use echo in PHP to display an image?

In PHP, you can use the echo statement to output images. However, it is important to note that the echo statement can only output the URL of the image, not the image itself.

Here is a simple example demonstrating how to use echo to output the URL address of an image.

<?php
$imageUrl = "https://example.com/image.jpg";

echo '<img src="' . $imageUrl . '" alt="Image">';
?>

In the example above, the $imageUrl variable holds the URL address of the image. Then an tag is output using the echo statement, with the src attribute value set to $imageUrl, indicating the image to display.

Please note that this just outputs the URL address of the image to the HTML page, rather than displaying the image itself on the browser. The browser will load and display the image based on the URL address.
