PHP分页类

标签： php mysql class pagination pager

我正在寻找一个php分页类，我过去使用了一个相当简单的类，它不再受支持。

我想知道是否有人有任何建议？

当那里有很多好的时候，建立我自己似乎毫无意义。

我建议Zend_Paginator出于以下原因

  • 它松散耦合，不需要整个库。
  • ZF社区比PEAR社区大，并且正在积极地对代码进行安全审核，并发布维护版本。
  • 它使用适配器模式分隔数据源，文档中有许多前端UI模式实现的示例。

经过多次搜索，我决定在使用框架版本之前，我应该完全理解paginator中涉及的内容。所以我自己建了一个。谢谢你的建议！

你试过PEAR::Pager吗？用法示例here。

你可以试试这个： Zebra_Pagination，一个用PHP编写的通用，Twitter Bootstrap兼容的分页类 检查以下链接： http://stefangabos.ro/php-libraries/zebra-pagination

// pagination class
class Pagination
{
    // database handle
    private $dbh;

    // total records in table
    private $total_records;

    // limit of items per page
    private $limit;

    // total number of pages needed
    private $total_pages;

    // first and back links
    private $firstBack;

    // next and last links
    private $nextLast;

    // where are we among all pages?
    private $where;

    public function __construct($dbh) {
        $this->dbh = $dbh;
    }

    // determines the total number of records in table
    public function totalRecords($query, array $params)
    {
        $stmt = $this->dbh->prepare($query);
        $stmt->execute($params);
        $this->total_records = $stmt->fetchAll(PDO::FETCH_COLUMN)[0];

        if (!$this->total_records) {
            echo 'No records found!';
            return;
        }
    }

    // sets limit and number of pages
    public function setLimit($limit)
    {
        $this->limit = $limit;

        // determines how many pages there will be
        if (!empty($this->total_records)) {
            $this->total_pages = ceil($this->total_records / $this->limit);
        }
    }

    // determine what the current page is also, it returns the current page
    public function page()
    {
        $pageno =  (int)(isset($_GET['pageno'])) ? $_GET['pageno'] : $pageno = 1;

        // out of range check
        if ($pageno > $this->total_pages) {
            $pageno = $this->total_pages;
        } elseif ($pageno < 1) {
            $pageno = 1;
        }

        // links
        if ($pageno > 1) {
            // backtrack
            $prevpage = $pageno -1;

            // 'first' and 'back' links
            $this->firstBack = "<div class='first-back'><a href='$_SERVER[PHP_SELF]?pageno=1'>First</a> <a href='$_SERVER[PHP_SELF]?pageno=$prevpage'>Back</a></div>";
        }

        $this->where =  "<div class='page-count'>(Page $pageno of $this->total_pages)</div>";

        if ($pageno < $this->total_pages) {
            // forward
            $nextpage = $pageno + 1;

            // 'next' and 'last' links
            $this->nextLast =  "<div class='next-last'><a href='$_SERVER[PHP_SELF]?pageno=$nextpage'>Next</a> <a href='$_SERVER[PHP_SELF]?pageno=$this->total_pages'>Last</a></div>";
        }

        return $pageno;
    }

    // get first and back links
    public function firstBack()
    {
        return $this->firstBack;
    }

    // get next and last links
    public function nextLast()
    {
        return $this->nextLast;
    }

    // get where we are among pages
    public function where()
    {
        return $this->where;
    }
}

使用：

$pagination = new Pagination($dbh);
$pagination->totalRecords('SELECT COUNT(*) FROM `photos` WHERE `user` = :user', array(':user' => $_SESSION['id']));
$pagination->setLimit(12);
$pagination->page();
echo $pagination->firstBack();
echo $pagination->where();
echo $pagination->nextLast();

结果：

<div class='first-back'><a href='/xampp/web_development/new_study_2014/imagebox2016/app/public/test.php?pageno=1'>First</a> <a href='/xampp/web_development/new_study_2014/imagebox2016/app/public/test.php?pageno=3'>Back</a></div>
<div class='page-count'>(Page 4 of 6)</div>
<div class='next-last'><a href='/xampp/web_development/new_study_2014/imagebox2016/app/public/test.php?pageno=5'>Next</a> <a href='/xampp/web_development/new_study_2014/imagebox2016/app/public/test.php?pageno=6'>Last</a></div>

    if ($stmt2->rowCount() > 0) {
        // Define how we want to fetch the results
        $stmt2->setFetchMode(PDO::FETCH_ASSOC);
        $iterator = new IteratorIterator($stmt2);

        // Display the results
        foreach ($iterator as $row) {
            echo '<p>'. $row['dn_title'].' - '. $row['artist_name'].'</p>';
        }

    } else {
        echo '<p>No results could be displayed.</p>';
    }



}

很可能你的SQL SELECT语句查询可能会导致1000条记录。但是在一个页面上显示所有结果并不是一个好主意。因此，我们可以根据分页类的要求将此结果划分为多个页面。

使用分页类别分享数据非常容易
