这个类可以用来搜索在给定的文本目录中的文件。 它可以给定目录遍历递归查找某些文件扩展名的文件。 并打开找到的文件,并检查他们是否包含搜索词语。 它返回一个含有所有文件的列表包含搜索词语数组。 <div class="codetitle"><a style="CURSOR: pointer" data="11684" class="copybut" id="copybut11684" onclick="doCopy('code11684')"> 代码如下:<div class="codebody" id="code11684"> <?php / Class for searching the contents of all the files in a directory and its subdirectories For support please visit http://www.webdigity.com/ / class searchFileContents{ var $dir_name = '';//The directory to search var $search_phrase = '';//The phrase to search in the file contents var $allowed_file_types = array('php','phps');//The file types that are searched var $foundFiles;//Files that contain the search phrase will be stored here //开源代码OSPHP.COM.Cn var $myfiles; function search($directory,$search_phrase){ $this->dir_name = $directory; $this->search_phrase = $search_phrase; $this->myfiles = $this->GetDirContents($this->dir_name); $this->foundFiles = array(); if ( empty($this->search_phrase) ) die('Empty search phrase'); if ( empty($this->dir_name) ) die('You must select a directory to search'); foreach ( $this->myfiles as $f ){ if ( in_array(array_pop(explode ( '.',$f )),$this->allowed_file_types) ){ //开源OSPhP.COM.CN $contents = file_get_contents($f); if ( strpos($contents,$this->search_phrase) !== false ) $this->foundFiles [] = $f; //开源代码OSPhP.COm.CN } } return $this->foundFiles; } function GetDirContents($dir){ if (!is_dir($dir)){die ("Function GetDirContents: Problem reading : $dir!");} if ($root=@opendir($dir)){ //PHP开源代码 while ($file=readdir($root)){ if($file=="." || $file==".."){continue;} if(is_dir($dir."/".$file)){ $files=array_merge($files,$this->GetDirContents($dir."/".$file)); }else{ $files[]=$dir."/".$file; //开源OSPhP.COM.CN } } } return $files; } } //Example : $search = new searchFileContents; $search->search('E:/htdocs/AccessClass','class'); //开源代码OSPHP.COM.Cn var_dump($search->foundFiles); ?>
