PHP 二维数组分页处理

两种方式,一种直接用array_slice(),另外一种是传统方式for循环次数的控制,大家看看给些意见,或者谁有更好的办法,也一并分享出来,谢谢。 

方法一:

<?php
$arr_click = array(
array( &#39;clicks&#39; => 3, &#39;clickDate&#39; =>&#39;2010-10-11&#39; ),
array( &#39;clicks&#39; => 2, &#39;clickDate&#39; =>&#39;2010-10-11&#39; ),
array( &#39;clicks&#39; => 3, &#39;clickDate&#39; =>&#39;2010-10-09&#39; ),
array( &#39;clicks&#39; => 1, &#39;clickDate&#39; =>&#39;2010-10-08&#39; ),
);
$page = 2;
$indexinpage=2;
$newarr = array_slice($arr_click, ($page-1)*$indexinpage, $indexinpage);
?>

原理如下:
和分页原理一样
数组用 array_slice(array,offset,length) 函数在数组中根据条件取出一段值。
array:需要处理的数组
offset:取出元素的开始位置
length:返回数组的长度
在每页中改变 offset 的值就行了!
方法二:
例如:

<?php
$arr_click = array(
array( &#39;clicks&#39; => 3, &#39;clickDate&#39; =>&#39;2010-10-11&#39; ),
array( &#39;clicks&#39; => 2, &#39;clickDate&#39; =>&#39;2010-10-11&#39; ),
array( &#39;clicks&#39; => 3, &#39;clickDate&#39; =>&#39;2010-10-09&#39; ),
array( &#39;clicks&#39; => 1, &#39;clickDate&#39; =>&#39;2010-10-08&#39; ),
);
$size = 3;
$pnum = ceil(count($arr_click) / $size);
if(isset($_GET[&#39;page&#39;])){
    $page = intval($_GET[&#39;page&#39;]);
    $page = $page > $pnum? $pnum: $page;
    $page = $page < $pnum? 1: $page;
}else{
    $page = 1;
}
for($i = 0; $i < $size; $i++){
    if(!isset($arr_click[($page - 1) * $size + $i]))break;
    echo &#39;<pre class="brush:php;toolbar:false">&#39;;
    print_r($arr_click[($page - 1) * $size + $i]);
    echo &#39;<br>&#39;;
}
?>
<a href="ad.php?page=<?php echo $page - 1 > 0? $page - 1: 1; ?>">上一页</a>
<a href="ad.php?page=<?php echo $page + 1 < $pnum? $page + 1: $pnum; ?>">下一页</a>

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
