这是个非常有用的程序,可以对文本文件进行特定的搜索,并以特定的文字替换指定的文字,举个例子说如果我这篇文章里有一个字全部打错了,有几十处,要一一找出来修改是件很麻烦的事,用下面这个就可以轻松搞定。--teaman.oso.com.cn 类文件 search_replace.inc ?php class search_replace{ var $find; var $replace; var $files; var $directories; var $include_subdir; var $ignore_lines; var $ignore_sep; var $occurences; var $search_function; var $last_error; //以下进行函数定义和设置 function search_replace($find, $replace, $files, $directories = '', $include_subdir = 1, $ignore_lines = array()){ $this-find= $find; $this-replace= $replace; $this-files= $files; $this-directories= $directories; $this-include_subdir= $include_subdir; $this-ignore_lines= $ignore_lines; $this-occurences= 0; $this-search_function = 'search'; $this-last_error= ''; } /*************************************** ** Accessor for retrieving occurences. ***************************************/ function get_num_occurences(){ return $this-occurences; } //获取最后的错误 function get_last_error(){ return $this-last_error; } //设置FIND变量 function set_find($find){ $this-find = $find; } //设置replace变量 function set_replace($replace){ $this-replace = $replace; } //设置FILE变量 function set_files($files){ $this-files = $files; } //设置目录变量 function set_directories($directories){ $this-directories = $directories; } //设置目录变量 set_include_subdir function set_include_subdir($include_subdir){ $this-include_subdir = $include_subdir; } //设置ignore_lines变量 function set_ignore_lines($ignore_lines){ $this-ignore_lines = $ignore_lines; } //确定是哪一种搜索方式 function set_search_function($search_function){ switch($search_function){ case 'normal': $this-search_function = 'search'; return TRUE; break; case 'quick' : $this-search_function = 'quick_search'; return TRUE; break; case 'preg': $this-search_function = 'preg_search'; return TRUE; break; case 'ereg': $this-search_function = 'ereg_search'; return TRUE; break; default: $this-last_error= 'Invalid search function specified'; return FALSE; break; } } //以下为搜索和替换程序的主文件 function search($filename){ $occurences = 0; $file_array = file($filename); for($i=0; $icount($file_array); $i++){ $continue_flag = 0; if(count($this-ignore_lines) 0){ for($j=0; $jcount($this-ignore_lines); $j++){ if(substr($file_array[$i],0,strlen($this-ignore_澳门新葡亰登入,lines[$j])) == $this-ignore_lines[$j]) $continue_flag = 1; } } if($continue_flag == 1) continue; $occurences += count(explode($this-find, $file_array[$i])) - 1; $file_array[$i] = str_replace($this-find, $this-replace, $file_array[$i]); } if($occurences 0) $return = array($occurences, implode('', $file_array)); else $return = FALSE; return $return; } //使用quick(快速)搜索方法时,没有igonre_lines功能 function quick_search($filename){ clearstatcache(); $file= fread($fp = fopen($filename, 'r'), filesize($filename)); fclose($fp); $occurences = count(explode($this-find, $file)) - 1; $file= str_replace($this-find, $this-replace, $file); if($occurences 0) $return = array($occurences, $file); else $return = FALSE; return $return; } //preg搜索方法不支持ignore_lines function preg_search($filename){ clearstatcache(); $file= fread($fp = fopen($filename, 'r'), filesize($filename)); fclose($fp); $occurences = count($matches = preg_split($this-find, $file)) - 1; $file= preg_replace($this-find, $this-replace, $file); if($occurences 0) $return = array($occurences, $file); else $return = FALSE; return $return; } //ereg搜索方法也不支持ignore_lines function ereg_search($filename){ clearstatcache(); $file = fread($fp = fopen($filename, 'r'), filesize($filename)); fclose($fp); $occurences = count($matches = split($this-find, $file)) -1; $file= ereg_replace($this-find, $this-replace, $file); if($occurences 0) $return = array($occurences, $file); else $return = FALSE; return $return; } //写新文件 function writeout($filename, $contents){ if($fp = @fopen($filename, 'w')){ fwrite($fp, $contents); fclose($fp); }else{ $this-last_error = 'Could not open file: '.$filename; } } //由do_search调用,排出所有要搜索的文件 function do_files($ser_func){ if(!is_array($this-files)) $this-files = explode(',', $this-files); for($i=0; $icount($this-files); $i++){ if($this-files[$i] == '.'
