TextSearch.class "Replacement Text is not defined"

Lukeup · March 20, 2009

Hi, this great script makes changes to all text files in any directory. I need to replace "\r\n " with "" but the script returns 'Replacement Text is not defined'. Can some one please help me remove this empty string restriction?? I'm fairly new to PHP but I know a great script when I find it. Any help would be greatly appreciated. Aren't Fridays great. Did I actually put too many greats in this post. Thanks, Luke.

usage script:

<?php

require_once('TextSearch.class.php');

$path = "c:\secu"; //setting search path

$logFile = "c:\secu\searchResult.txt"; //setting log file

$obj = new TextSearch();

$obj->setExtensions(array('txt')); //setting extensions to search files within

$obj->addExtension('php');//adding an extension to search within

$obj->setSearchKey("\r\n ");

$obj->setReplacementKey("");//setting replacement text if you want to replace matches with that

$obj->startSearching($path);//starting search

$obj->showLog();//showing log

$obj->writeLogToFile($logFile); //writting result to log file

?>
