php 目录递归遍历程序_PHP教程

一个朋友写的一款目录查找程序，可以根据用户输入的目录名称查到到指定目录或文件，同时还支持锁定目录哦，有需要的朋友可以参考一下。

代码如下

复制代码

class Finder{  private $key;  private $result;  private $previewLen = 50;  private $file_type = array('html','php','htm','txt');  function __construct($key){   $this->key = $key;  }  function find($folder){   $this->result = array();      if(is_array($folder)){    foreach($folder as $f){     $this->_find_in_folder($f);    }   }else{    $this->_find_in_folder($folder, true);   }   return $this->result;  }    function _find_in_folder($folder,$bSub=false){   foreach(glob($folder.DIRECTORY_SEPARATOR.'*') as $f){    if (is_file($f)){     $extend =explode("." , $f);     $type = strtolower(end($extend));     if(in_array($type,$this->file_type)){      $fd = file_get_contents($f);      $pos = strpos($fd,$this->key);      if($pos!==false){       $end = $pre = '...';       $pos -= floor($this->previewLen/2);       if($pos       $pre = '';        $pos = 0;       }       $findata = substr($fd,$pos,$this->previewLen);       $findata = str_replace($this->key,''.$this->key.'',$findata);       $this->result[] = array('path'=>$f,'preview'=>$pre.$findata.$end);      }     }     continue;    }    if($bSub && is_dir($f)){     $this->_find_in_folder($f,true);    }   }  }   } $cur_path = dirname(__FILE__); if(isset($_GET['a'])){  $key = $_POST['key'];  if(!$key) die('关键字不能为空');  $cf = new Finder($key);  $in_folder = array();  $limit_folder = $_POST['limit_folder'];  if($limit_folder==1){   if(!isset($_POST['folder']) || !$_POST['folder']) die('限定目录不能为空');   $in_folder = $_POST['folder'];   $ret = $cf->find($in_folder);  }else{   $ret = $cf->find($cur_path);  }  echo "搜索[$key]结果： ";  if(!$ret) die('无');  foreach($ret as $p=>$f){   echo "$p. t$f[path] => $f[preview] n";  }  exit();  } $folder = array(); function readFolder($path){  global $folder;  $folder[] = $path;  foreach(glob($path.DIRECTORY_SEPARATOR.'*') as $f){   if (is_dir($f)) {    readFolder($f);   }  } } readFolder($cur_path); $folder_op = array(); foreach($folder as $path){  $folder_op[] = "$path"; } $folder_op = implode($folder_op); ?> 搜索关键字： 搜索目录： 是否限定以上选择的目录：是 否 =
