How to add PHP pagination in array's
提问by Arqetech
I've been trying a lot of ways to add PHP pagination. I have tried searching and trying to figure other ways of implementing the pagination but none of them work.
我一直在尝试很多方法来添加 PHP 分页。我尝试搜索并尝试找出实现分页的其他方法，但没有一个有效。
Here's how I created the Index page:
这是我创建索引页面的方式：
<?php
$menuItems = array(
"post1" => array(
"title" => "Sample Title",
"utime" => "M/d/Y",
"content" => "<p>Body of the post</p>"
),
"post2" => array(
"title" => "Another Sample Title",
"utime" => "M/d/Y",
"content" => "<p>Content goes here...</p>"
),
);
foreach ($menuItems as $contItem => $item) {
?>
<li>
<a href="dish.php?item=<?php echo $contItem; ?>">
<h1><?php echo $item["title"]; ?></h1>
<small><?php echo $item["utime"]; ?></small>
</a>
</li>
<?php } ?>
I would like to know how I can paginate the the array list. Thanks!

u can use simple PHP function called array_slice()
您可以使用名为array_slice() 的简单 PHP 函数
$menuItems = array_slice( $menuItems, 0, 10 );
show first 10 items.
显示前 10 个项目。
$menuItems = array_slice( $menuItems, 10, 10 );
show next 10 items.
显示接下来的 10 个项目。
UPDATE:
更新：
$page = ! empty( $_GET['page'] ) ? (int) $_GET['page'] : 1;
$total = count( $yourDataArray ); //total items in array
$limit = 20; //per page
$totalPages = ceil( $total/ $limit ); //calculate total pages
$page = max($page, 1); //get 1 page when $_GET['page'] <= 0
$page = min($page, $totalPages); //get last page when $_GET['page'] > $totalPages
$offset = ($page - 1) * $limit;
if( $offset < 0 ) $offset = 0;
$yourDataArray = array_slice( $yourDataArray, $offset, $limit );
UPDATE#2:
更新#2：
Example of pagination:
分页示例：
$link = 'index.php?page=%d';
$pagerContainer = '<div style="width: 300px;">';
if( $totalPages != 0 )
{
if( $page == 1 )
{
$pagerContainer .= '';
}
else
{
$pagerContainer .= sprintf( '<a href="' . $link . '" style="color: #c00"> « prev page</a>', $page - 1 );
}
$pagerContainer .= ' <span> page <strong>' . $page . '</strong> from ' . $totalPages . '</span>';
if( $page == $totalPages )
{
$pagerContainer .= '';
}
else
{
$pagerContainer .= sprintf( '<a href="' . $link . '" style="color: #c00"> next page » </a>', $page + 1 );
}
}
$pagerContainer .= '</div>';
echo $pagerContainer;

Another viable option is to use array_chunk():
另一个可行的选择是使用array_chunk()：
$pagedArray = array_chunk($originalArray, 10, true);
$nthPage = $pagedArray[$pageNumber];
