Solution:
Step 1: Import Bootstrap
First, you need to import the Bootstrap framework into your project. You can do this by downloading the necessary CSS and JavaScript files from the official Bootstrap website or by using a CDN link.
Step 2: Create Pagination HTML Markup
Next, you need to create the HTML markup for your pagination. This will be inside your main PHP page or template where you want to display the pagination. You can use the following code:
```
<nav aria-label="Page navigation">
<ul class="pagination">
<li class="page-item">
<a class="page-link" href="#" aria-label="Previous">
<span aria-hidden="true">«</span>
<span class="sr-only">Previous</span>
</a>
</li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item">
<a class="page-link" href="#" aria-label="Next">
<span aria-hidden="true">»</span>
<span class="sr-only">Next</span>
</a>
</li>
</ul>
</nav>
```
Step 3: Create the Pagination Function in PHP
Next, you need to create a function in your PHP code that will handle the pagination logic. You can modify this function as per your project requirements. The following code is a basic pagination function that takes the total number of records, current page, and number of records to display per page as parameters.
```
function paginate($total_records, $current_page, $records_per_page){
// Calculate total pages
$total_pages = ceil($total_records / $records_per_page);
// Make sure current page is within range
if ($current_page > $total_pages) {
$current_page = $total_pages;
}
elseif ($current_page < 1) {
$current_page = 1;
}
// Calculate offset for SQL query
$offset = ($current_page - 1) * $records_per_page;
// Return array with pagination data
return [
'current_page' => $current_page,
'total_pages' => $total_pages,
'offset' => $offset
];
}
```
Step 4: Use the Pagination Function in Your Code
Now you can use the pagination function in your PHP code to get the necessary data for the pagination. For example, if you are retrieving data from a database, you can use the offset value in your SQL query to get the specified number of records per page.
```
// Get total number of records from database
$total_records = $pdo->query("SELECT COUNT(*) FROM posts")->fetchColumn();
// Set records per page
$records_per_page = 10;
// Get current page from URL parameter or use default value
$current_page = isset($_GET['page']) ? (int)$_GET['page'] : 1;
// Call pagination function
$pagination_data = paginate($total_records, $current_page, $records_per_page);
// Use the returned data to modify your database query
$results = $pdo->query("SELECT * FROM posts LIMIT " . $pagination_data['offset'] . ", " . $records_per_page)->fetchAll();
```
Step 5: Add Active Class to Current Page Link
To highlight the current page in your pagination, you can add the "active" class to the current page link using the following code:
```
<ul class="pagination">
<li class="page-item <?php echo $current_page == 1 ? 'active' : ''; ?>">
<a class="page-link" href="?page=1">1</a>
</li>
<li class="page-item <?php echo $current_page == 2 ? 'active' : ''; ?> ">
<a class="page-link" href="?page=2">2</a>
</li>
...
</ul>
```
Step 6: Style Your Pagination
Finally, you can customize the look and feel of your pagination using the CSS classes provided by Bootstrap such as "pagination", "page-link", "page-item", etc. You can also use your own CSS to create a custom pagination design.
Conclusion:
By following the above steps, you can easily create a PHP Bootstrap pagination for your project. You can also add additional features such as previous/next links, page numbers, etc. as per your requirements. Remember to test your pagination with different page scenarios and make necessary adjustments to your code.
