Prerequisites
- Basic understanding of PHP.
- A local or remote server supporting PHP.
- A folder with images.
Setting Up Your Environment
Before diving into the code, ensure you have a local server like XAMPP or MAMP.
1. Directory Structure
Organize your files:
/autogallery/
/images/
index.phpBuilding the PHP AutoGallery
1. Scan the Directory
Use PHP’s scandir() function.
<?php $directory = 'images/'; $images = scandir($directory); $filtered_images = array_diff($images, array('.', '..')); ?>2. Display the Images
Loop through the filtered images to display them.
<?php foreach ($filtered_images as $image) { echo "<img src='$directory$image' alt='Gallery Image' />"; } ?>3. Style Your Gallery
Use CSS to make it visually appealing. This example provides a basic grid.
img { width: 200px; height: auto; margin: 10px; }Learn more about CSS on Wikipedia
Enhancements
1. Image Sorting
Sort images alphabetically or by date using PHP’s sort() function.
sort($filtered_images);2. Responsive Design
Use Bootstrap to make your gallery responsive.
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css"> <div class="row"> <?php foreach ($filtered_images as $image) { echo " <div class='col-lg-3 col-md-4 col-sm-6'> <img class='img-fluid' src='$directory$image' alt='Gallery Image' /> </div> "; } ?> </div>Learn more about Bootstrap on Wikipedia
Complete AutoGallery Example
1. index.php:
<?php
$directory = 'images/';
$images = scandir($directory);
$filtered_images = array_diff($images, array('.', '..'));
sort($filtered_images);
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">

<div class="container">
<h2>My PHP AutoGallery</h2>
<div class="row">
<?php
foreach ($filtered_images as $image) {
echo "
<div class='col-lg-3 col-md-4 col-sm-6'>
<img class='img-fluid' src='$directory$image' alt='Gallery Image' />
</div>
";
}
?>
</div>
</div>
</body>
</html>2. styles.css:
img {
width: 100%;
height: auto;
margin: 10px 0;
}
h2 {
text-align: center;
margin: 20px 0;
}To make this work:
- Create a folder named
autogalleryon your local server (e.g., inside thehtdocsfolder if you’re using XAMPP). - Inside the
autogalleryfolder, create another folder namedimagesand upload your pictures there. - Put the
index.phpandstyles.cssfiles inside theautogalleryfolder.
Now, when you navigate to http://localhost/autogallery/ in your browser, you’ll see the gallery in action!
