搜尋和取代檔案或目錄的好類--很實用

這是個非常有用的程序，可以對文本文件進行特定的搜索，並以特定的文字替換指定的文字，舉個例子說如果我這篇文章裡有一個字全部打錯了，有幾十個地方，要一一找出來修改是件很麻煩的事，用下面這個就可以輕鬆搞定。--teaman.oso.com.cn

//下面是呼叫該類別的例子說明,請存為example.php
        include('search_replace.inc');將檔案包含進來
//建立新物件，設定搜尋條件、最後回傳搜尋結果
        $sr = new search_replace('asp', 'php', array('test.txt')); //呼叫搜尋與替換
        $sr->set_search_function('quick');   //設定搜尋條件
       );
        $sr->do_search();
//下面是客製化的回傳資訊
        header('Content-Type: .$sr->get_num_occurences()."rn";
        echo '啊，錯誤發生如下.............: '.$sr->get_last_error()."rn" ;
?>
//將以下文字存為test.txt,注意text.txt必須是可讀可寫的
"我很喜歡asp,它簡單易學，功能強，聽說asp已經佔了大半市場，asp真好。 ................:      
查看test.txt文件，果然出現asp的地方被php取代了。
