Lukeup Posted March 20, 2009 Share Posted 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 ?> TextSearch.class.php: <?php /** * Class : TextSearch * * @author : MA Razzaque Rupom <rupom_315@yahoo.com>, <rupom.bd@gmail.com> * Moderator, phpResource Group(http://groups.yahoo.com/group/phpresource/) * URL: http://rupom.wordpress.com * * @version : 1.0 * Date : 06/25/2006 * Purpose : Searching and replacing text within files of specified path */ class TextSearch { var $extensions = array(); var $searchKey = ''; var $replacementKey = ''; var $caseSensitive = 0; //by default case sensitivity is OFF var $findAllExts = 1; //by default all extensions var $isReplacingEnabled = 0; var $logString = ''; var $errorText = ''; var $totalFound = 0; //total matches /** * Sets extensions to look * @param Array extensions * @return none */ function setExtensions($extensions = array()) { $this->extensions = $extensions; if(sizeof($this->extensions)) { $this->findAllExts = 0; //not all extensions } }//End of Method /** * Adds a search extension * @param file extension * @return none */ function addExtension($extension) { array_push($this->extensions, $extension); $this->findAllExts = 0; //not all extensions }//End of function /** * Sets search key and case sensitivity * @param search key, case sensitivity * @return none */ function setSearchKey($searchKey, $caseSensitive = 0) { $this->searchKey = $searchKey; if($caseSensitive) { $this->caseSensitive = 1; //yeah, case sensitive } }//End of function /** * Sets key to replace searchKey with * @param : replacement key * @return none */ function setReplacementKey($replacementKey) { $this->replacementKey = $replacementKey; $this->isReplacingEnabled = 1; }//End of function /** * Wrapper function around function findDirFiles() * @param $path to search * @return none */ function startSearching($path) { $this->findDirFiles($path); }//EO Method /** * Recursively traverses files of a specified path * @param path to execute * @return none */ function findDirFiles($path) { $dir = opendir ($path); while ($file = readdir ($dir)) { if (($file == ".") or ($file == "..")) { continue; } if (filetype ("$path/$file") == "dir") { $this->findDirFiles("$path/$file"); //recursive traversing here } elseif($this->matchedExtension($file)) //checks extension if we need to search this file { if(filesize("$path/$file")) { $this->searchFileData("$path/$file"); //search file data } } } //End of while closedir($dir); }//EO Method /** * Finds extension of a file * @param filename * @return file extension */ function findExtension($file) { return array_pop(explode(".",$file)); }//End of function /** * Checks if a file extension is one the extensions we are going to search * @param filename * @return true in success, false otherwise */ function matchedExtension($file) { if($this->findAllExts) //checks if all extensions are to be searched { return true; } elseif(sizeof(array_keys($this->extensions, $this->findExtension($file)))==1) { return true; } return false; }//EO Method /** * Searches data, replaces (if enabled) with given key, prepares log * @param $file * @return none */ function searchFileData($file) { $searchKey = preg_quote($this->searchKey, '/'); if($this->caseSensitive) { $pattern = "/$searchKey/U"; } else { $pattern = "/$searchKey/Ui"; } $subject = file_get_contents($file); $found = 0; $found = preg_match_all($pattern, $subject, $matches, PREG_PATTERN_ORDER); $this->totalFound +=$found; if($found) { $foundStr = "Found in $found places"; $this->appendToLog($file, $foundStr); } if($this->isReplacingEnabled && $this->replacementKey && $found) { $outputStr = preg_replace($pattern, $this->replacementKey, $subject); $foundStr = "Found in $found places"; $this->writeToFile($file, $outputStr); $this->appendToLog($file, $foundStr, $this->replacementKey); } elseif($this->isReplacingEnabled && $this->replacementKey == '') { $this->errorText .= "Replacement Text is not defined\n"; $this->appendToLog($file, "Replacement Text is not defined", $this->replacementKey); } elseif(!found) { $this->appendToLog($file, "No matching Found", $this->replacementKey); } }//EO Method /** * Writes new data (after the replacement) to file * @param $file, $data * @return none */ function writeToFile($file, $data) { if(is_writable($file)) { $fp = fopen($file, "w"); fwrite($fp, $data); fclose($fp); } else { $this->errorText .= "Can not replace text.
