PHP multi-page jump for array paging

Introduction

When processing Pagination is essential when working with large arrays or data sets. It allows the user to browse a subset of the data without loading the entire array. In this case, multi-page jumps can significantly enhance the user experience. This article will guide you on how to implement multi-page jumps in array paging in PHP.

Code example

The following is a sample code to implement array paging and multi-page jump:

<?php
// 定义输入数组
$array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

// 每页显示的项目数量
$pageSize = 3;

// 当前页码（默认为 1）
$currentPage = (int) ($_GET['page'] ?? 1);

// 计算总页数
$totalPages = ceil(count($array) / $pageSize);

// 计算当前页的偏移量
$offset = ($currentPage - 1) * $pageSize;

// 分页后的数组
$currentPageArray = array_slice($array, $offset, $pageSize);

// 生成分页链接
$paginationLinks = '';
for ($i = 1; $i <= $totalPages; $i++) {
    $paginationLinks .= '<a href="?page=' . $i . '">' . $i . '</a> ';
}

// 输出分页数据
echo '<div>当前页：' . $currentPage . '</div>';
echo '<div>每页项目数量：' . $pageSize . '</div>';
echo '<div>总页数：' . $totalPages . '</div>';
echo '<div>当前页的数组：' . implode(', ', $currentPageArray) . '</div>';
echo '<div>分页链接：' . $paginationLinks . '</div>';
?>

Practical case

Suppose you have an array containing a list of users. You can use the code above to paginate the data based on the number of users per page. When a user clicks a link to a page, the code loads and displays that page to the user.

Advantages

• Enhanced user experience, allowing easy browsing of large data sets.
• Reduce server load because only one page of data is loaded at a time.
• Simplify management and maintenance of large arrays.
