php文件名与文件内容查找器实例
搜索文件很简单只要用户输入目录我们就会自动遍历目录找到相关联的文件名并列出来,下面我们一起来看看吧。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 | 复制代码 |
<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(!empty($_POST['path'])&&!empty($_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(empty($loop[$countArr])){ echo " <span style='color:#297C79;'><b> $dirName </b></span><br />n"; $GLOBALS['r_dir_num']++; } } }else{ die("没有此路径!"); } }
echo "<hr/>本次共搜索到".$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 | 复制代码 |
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 .

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