php文件名与文件内容查找器实例

时间：2015-01-23 来源：西部数据作者：西部数据

php文件查找程序，输入一个路径确定后会遍历目录下所有的文件和文件夹,通过递归可以找到文件夹下面的每一个文件,再通过文件名和输入的关键字匹配,则可以查找到你想要的文件,对于本地,我们可以利用windows自带的查找去进行查找,但是对于线上的话,如查找ftp空间里面文件,本程序是很有用的.

php文件查找器源码,代码如下:

<html>

<head>

  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

  <title>php版文件查找（file search）</title>

</head>

<body>

  <form action="" method="post">

  <p> 文件查找（注：区分大小写）</p>

  <p>路径：<input type="text" name="path" /></p>

  <p>查找：<input type="text" name="key" /></p>

  <p><input type="submit" name="sub" value=" 开始 " /></p>

  </form>

</body>

</html>

<?php

/*

* 注：区分大小写

*/

if(!emptyempty($_POST['path'])&&!emptyempty($_POST['key'])){

echo "在路径 ".$_POST['path']."/ 中查找 ".$_POST['key']." 的结果为：<hr/>";

$file_num = $dir_num = 0;

$r_file_num = $r_dir_num= 0;

$findFile = $_POST['key'];

function delDirAndFile( $dirName ){

  if ( $handle = @opendir( "$dirName" ) ) {

   while ( false !== ( $item = readdir( $handle ) ) ) {

    if ( $item != "." && $item != ".." ) {

     if ( is_dir( "$dirName/$item" ) ) {

      delDirAndFile( "$dirName/$item" );

     } else {

      $GLOBALS['file_num']++;

      if(strstr($item,$GLOBALS['findFile'])){

       echo " <span><b> $dirName/$item </b></span><br />n";

       $GLOBALS['r_file_num']++;

      }

     }

    }

   }

   closedir( $handle );

   $GLOBALS['dir_num']++;

   if(strstr($dirName,$GLOBALS['findFile'])){

    $loop = explode($GLOBALS['findFile'],$dirName);

    $countArr = count($loop)-1;

    if(emptyempty($loop[$countArr])){

     echo " <span style='color:#297C79;'><b> $dirName </b></span><br />n";

     $GLOBALS['r_dir_num']++;

    }

   }

  }else{

   die("没有此路径！");

  }

}

delDirAndFile($_POST['path']);

echo "<hr/>本次共搜索到".$file_num."个文件，文件夹".$dir_num."个<br/>";

echo "<hr/>符合结果的共".$r_file_num."个文件，文件夹".$r_dir_num."个<br/>";

}

?>

上面只是查找文件,下面看一个查找文件中的字符是否包括我们要找的东西,自己写的一个批量查找文件内容的php程序,我是拿来扫描文件特征码的,现在我贴出代码,供大家参考,代码如下:

<?php

if ($_POST ['Submit'] == '开始') {

$total = 0; //文件总数

$dangerous = array (); //危险文件

$dangerous_content = $_POST ["sstr"];

$find_path = $_POST ["searchpath"];

$shortname = $_POST ["shortname"];

echo "<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Transitional//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'>";

echo "<html>";

echo "<head>";

echo "<meta http-equiv='Content-Type' content='text/html; charset=utf-8' />";

echo "</head>";

echo "<body>";

$begin_time=date("U");

// $dangerous_content = "小亮,Root_GP,Root_CSS,c99sh_updateurl,c99sh_sourcesurl,640684770";

visitFile ( $find_path, $shortname );

$end_time=date("U");

foreach ($dangerous as $d){

  echo $d."<br/>";

}

echo "查找文件总数:" . $total." 危险文件:".count($dangerous)." 总用时".($end_time-$begin_time)."秒";

echo "</body>";

echo "</html>";

//if (! empty ( $dangerous )) {

  //foreach ( $dangerous as $dan ) {

//echo "[error]" . $dan . "<br/>";

//}

//}

exit();

}

function visitFile($path, $ext) {

global $total;

global $dangerous_content;

$fdir = dir ( $path );

//echo "Handle: " . $d->handle . "<br>";

// echo "Path: " . $fdir->path . "<br>";

set_time_limit ( 24 * 60 * 60 );

while ( ($entry = $fdir->read ()) !== false ) {

  $pathSub = $path . "\" . $entry;

  if ($entry != '.' && $entry != '..') {

   if (is_dir ( $pathSub )) {

    visitFile ( $pathSub, $ext );

   } else {

    $exten = explode ( '.', $entry );

    $exten = array_reverse ( $exten ); //把上面数组倒序

    //   foreach ()

    $shortnames = explode ( '|', $ext );

    foreach ( $shortnames as $sn ) {

     if (! emptyempty ( $exten ) && $sn == $exten [0]) {

      $total = $total + 1;

      //echo "开始分析文件:".$path."/".$entry . "<br>";

      $content = file_get_contents ( $path . "/" . $entry ); //这个性能较好

      $content = strtolower ( $content ); //全部转为小写

      $dangerous_content = strtolower ( $dangerous_content ); //全部转为小写

      isExists ( $dangerous_content, $path . "/" . $entry, $content );//这个方法太耗内存了，希望有高手能解决一下

     }

    }

    //sleep(1);

   }

  }

}

$fdir->close ();

}

function isExists($str, $filename, $content) {

global $dangerous;

//sleep ( 1 );

set_time_limit ( 10 );

$arr = explode ( ',', $str );

$signature="特征码：";

if (! emptyempty ( $arr )) {

  //  $content = file_get_contents ( $filename ); //这个性能较好

  $content = strtolower ( $content ); //全部转为小写

  $error_count = 0;

  foreach ( $arr as $a ) {

   if (trim ( $a ) != "") {

    if (strpos ( $content, $a )) {

     $error_count = $error_count + 1;

     $signature.=$a." ";

    }

   }

  }

  if ($error_count > 0) {

//   $dangerous [] = $filename;

   $dangerous [] = "[error] " . $error_count . " " .$signature." " . $filename;

   //echo "[error] " . $error_count . " " .$signature." " . $filename . "<br/>";

  }else{

   //echo "[ok] "  . $filename . "<br/>";

  }

}

}
