A global search and replace using PHP. You'll need to specify several parameters as GET/POST parameters: oldword=[text to replace] newword=[new text] rootpath=[path to dir containing files to alter] Note also that PHP must have read/write access to the files to alter them.

<?php

                                exec("/bin/grep -r '$oldword' $rootpath", $results, $errorCode);

                                if ($errorCode){

                                    if ($errorCode == 1){

                                        echo "Possibly no files were found with $oldword in them<BR>n";

                                    }

                                  echo "OS Error: $errorCode<BR>n";

                                  echo "Check 'man errno' and count down<BR>n";

                                  echo "Usually paths/permissions<BR>n";

                                }

                                while (list(,$path) = each($results)){

                                    $parts = explode(':', $path);

                                    $path = $parts[0];

                                  $fp = fopen($path, 'r') or print("Cannot read $path<BR>n");

                            

                                  if ($fp){

                                    $data = fread($fp, filesize($path));

                                    fclose($fp);

                                    $newdata = str_replace($oldword, $newword, $data);

                                    $fp = fopen($path, 'w') or print("Cannot write $path<BR>n");

                                    if ($fp){

                                      fwrite($fp, $newdata);

                                      fclose($fp);

                                      echo $path, "<BR>n";

                                    }

                                  }

                                }
 ?>
