srt_replace()这个函数是什么意思？to zpfleaf(啊风)上面的这句话应该加在什么地方呢？
谢谢！

放在你要显示这个字符串之前的任何地方。
是替换的意思。将$save中的"关键字"替换成"<font color=red>关键字</font> "

srt_replace()--->str_replace()
字符串处理函数库
str_replace
字符串取代。语法: string str_replace(string needle, string str, string haystack);返回值: 字符串函数种类: 资料处理

内容说明
本函数将字符串 str 代入 haystack 字符串中，将所有的 needle 置换成 str。[email protected] (11-Apr-1999) 指出在 PHP 3.0.7 版，本函数有些 bug，而 [email protected] (05-Jun-1999) 补充在 PHP 3.0.8 版本函数就回复正常了。

使用范例
下例将 %body% 以 black 取代<?php
$bodytag = str_replace("%body%", "black", "<body text=%body%>");
echo $bodytag;
?>

我的一段代码，搜索目录下的文件，带分页显示，关键字加亮
有点乱，我自己都懒得看了$Search = trim($Search);
$recordnum = 10; //每页显示的记录数
echo "<div align=right><font color=#003399>关键字</font><font color=red>".$Search."</font></div>";
$to = "<font color=red>".$Search."</font>";
//读取文件目录到数组
$handle=opendir('./updata');
while ($file = readdir($handle)) {
if (!is_dir($file)){
$dir[$i] = './updata/'.$file;
$i++;}}
$count = count($dir);
//echo $count;
closedir($handle);
$handle=opendir('../JBFG');
while ($file = readdir($handle)) {
if (!is_dir($file)){
$dir[$count] = '../JBFG/'.$file;
$count++;}}
