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[] = "";
}
$folder_op = implode($folder_op);
?>
