//下面是调用该类的例子说明,请存为example.php

<?php

        include('search_replace.inc');  //将文件包括进来

//建立新物件，设置搜索条件、最后返回搜索结果

        $sr = new search_replace('asp', 'php', array('test.txt')); //调用搜索与替换
        $sr->set_search_function('quick');   //设置搜索条件
        $sr->do_search();

        $sr->set_find('another');
        $sr->do_search();

//下面是定制的返回信息
        header('Content-Type: text/plain');
        echo '发现和替换以下几个地方: '.$sr->get_num_occurences()." ";
        echo '啊，错误发生如下.............: '.$sr->get_last_error()." ";
?>

//将以下文字存为test.txt,注意text.txt必须是可读可写的
"我非常喜欢asp,它简单易学，功能强，听说asp已经占了大半市场，asp真好。"

此时，如果您打开exampe.php 就会出现下面这些：
发现和替换以下几个地方:3
啊，错误发生如下..........:      
查看test.txt文件，果然出现asp的地方被php替换了。
