php - Pulse CMS - 最近的帖子 - 显示 (100) 个字符

Question

有一个客户来找我关于那里的网站，他们正在使用 Pulse CMS，他们想在主页上显示最近的帖子，很容易......但我看不出如何显示一小部分帖子。我的php知识有限。

这是代码：

<?php
error_reporting(0);
include_once("config.php"); 
include_once("path.php");
include_once("helpers/blog_lib.php");
include_once("helpers/functions.php");

if($pulse_lang == 0){
include_once("lang.php");}  
else
if($pulse_lang == 1){
include_once("lang_de.php");}

$blog_file = new read_File("blog");$amount = $blog_file->countLines();
$lines = $blog_file->getLines();$amount_view = 1 ;

echo "<div class=\"span3 latest-post-1\">\n\n";

for ($n=$amount-1  ;  $n>=($amount - $amount_view)  ;  $n-- ) { 
$blog = explode("|", $lines[$n]);

if (isset($blog[0]) & $blog[0] != '') {

    $date = explode( ' ' , $blog[2]);
    $date = $date[2] . ' ' . $date[1]  . ' ' . $date[3];

    include("clean_url.php");

    if($rewrite) {

        if ($blog_comments) {

            echo "<p><a href=\"/blog-". $blog[0]     ."-".cleanUrlname($blog[3])."\">" .$blog[3]. "</a> (" .$blog[1]. ")<br>";

        } else {

            echo "<p><a href=\"/blog-". $blog[0] ."-".cleanUrlname($blog[3])."\">" .$blog[3]. "</a><br>";
        }

    } else { 

        if ($blog_comments) {

            echo "<p><a href=\"". $blog_url ."?d=". $blog[0] ."\">"    .$blog[3]."</a> (" .$blog[1]. ")<br>";

        } else {

            echo "<p><a href=\"". $blog_url ."?d=". $blog[0] ."\">" .$blog[3]."</a><br>";

        }
    }

    if($date_format) {

        echo date("d.m.Y", strtotime($date))."</p>\n\n";

    } else {

        echo date("m-d-Y", strtotime($date))."</p>\n\n";
    } 
}
}

echo "<p class=\"all-posts\"><a href=\"". $blog_url ."\">$lang_blog_see_all</a></p>";
echo "\n\n</div>";
?>

它只是从 .txt 文件中获取博客文章的标题和日期，因此肯定有人可以将文章的“100”个字符拉出来。

这是读取文件的代码：
