How can a beginner in PHP effectively integrate a gallery into a webpage without using iframes?

To integrate a gallery into a webpage without using iframes, a beginner in PHP can create a gallery using HTML and CSS, and then use PHP to dynamically generate the gallery content. By storing image file names in an array or database, the PHP code can loop through the images and display them on the webpage. This allows for flexibility in adding or removing images from the gallery without needing to edit the HTML code.

<div class="gallery">
    <?php
    $images = array("image1.jpg", "image2.jpg", "image3.jpg");
    
    foreach($images as $image) {
        echo '<img src="images/' . $image . '" alt="' . $image . '">';
    }
    ?>
</div>
