php文件名与文件内容查找器实例

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/>";
- }
- }
- }
- ?>
