What is the correct syntax for echoing an image tag in PHP?

When echoing an image tag in PHP, you need to make sure to properly concatenate the HTML code with the PHP variables or strings. The correct syntax for echoing an image tag includes using the 'echo' statement with the HTML image tag enclosed in double quotes, and concatenating any dynamic content within the tag using the period (.) operator.

<?php
$imageUrl = "path/to/image.jpg";
$altText = "Image Description";
echo "<img src='" . $imageUrl . "' alt='" . $altText . "'>";
?>
