PHP 文本文章分頁(yè)代碼按標(biāo)記或長(zhǎng)度（不涉及數(shù)據(jù)庫(kù)）

PHP文本分頁(yè)，按標(biāo)記或者長(zhǎng)度分頁(yè)，非傳統(tǒng)的數(shù)據(jù)庫(kù)分頁(yè)。廢話不多說(shuō)，客觀如有意可直接看代碼

實(shí)例代碼：

 
<?php 
/** 
* ********************************************************** 
* Read Me 
* 文章分頁(yè) 
* 
* 分頁(yè)方式，可以按字?jǐn)?shù)分頁(yè)，按換行分頁(yè)，按特殊標(biāo)記分頁(yè)等 
* 其實(shí)實(shí)現(xiàn)思路是一樣的，只是將其按一定規(guī)律放入一個(gè)數(shù)組 
* 然后根據(jù) url 傳入的參數(shù)取得某個(gè)片段即可 
* 大家完全可以寫(xiě)一個(gè)功能強(qiáng)大的函數(shù)保存起來(lái)以備不時(shí)之需 
* 
* 題外話：很多編輯器都有插入分頁(yè)按鈕，利用插入的代碼可顯示分頁(yè)

Hey, guys. I am here to test if it is working. 
This pagination is very simple, isn't it?<!--pagination--> 
And I tried to use different method to page it. 
Can you see it?

//當(dāng)前文章頁(yè)

$perpage = 160; 
//顯示在頁(yè)面的代碼 
$link = ''; 
//分割后的數(shù)組

$page = isset($_GET['page']) ? intval($_GET['page']) : 0; 
$length = strlen($data); 
//按字?jǐn)?shù)分割 
// $str = str_split($data, $perpage); 
//按字符分割 
$delimiter = "\n";

}
