Php file lookup program. After a path is entered, all the files and folders under the directory will be traversed, and each file under the folder can be found recursively, and then matched with the entered keyword through the file name, you can find the desired file. For local systems, we can use the search provided by windows for search. However, for online systems, such as searching for files in the ftp space, this program is very useful.


Php file finder source code:

The code is as follows: Copy code

<Html>

<Head>

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

<Title> file search for php </title>

</Head>

<Body>

<Form action = "" method = "post">

<P> File Search (note: case sensitive) </p>

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

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

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

</Form>

</Body>

</Html>

<? Php

/*

* Note: Case Sensitive

*/

If (! Empty ($ _ POST ['path']) &! Empty ($ _ POST ['key']) {

Echo "in path ". $ _ POST ['path']. "/in Search ". $ _ POST ['key']. "Result:

$ 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 ("This path is not available! ");

  }

 }

 


DelDirAndFile ($ _ POST ['path']);

Echo "

Echo "

}

 


?>

The above is just a file search. Let's see if the characters in the search file contain what we are looking.

I wrote a php program to search file content in batches. I used it to scan file signatures. Now I post the code for your reference.

The code is as follows: Copy code


<? Php

If ($ _ POST ['submit '] = 'start '){

$ Total = 0; // total number of files

$ Dangerous = array (); // dangerous file

$ 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 "

Echo "

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

Echo "

Echo "<body> ";

$ Begin_time = date ("U ");

// $ Dangerous_content = "Xiaoliang, 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 "total number of files:". $ total. "dangerous files:". count ($ dangerous). "total time". ($ end_time-$ begin_time). "seconds ";

Echo "</body> ";

Echo "

// 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); // returns the reverse order of the preceding array.

// Foreach ()

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

Foreach ($ shortnames as $ sn ){

If (! Empty ($ exten) & $ sn =$ exten [0]) {

$ Total = $ total + 1;

// Echo "start analysis File:". $ path. "/". $ entry. "<br> ";

$ Content = file_get_contents ($ path. "/". $ entry); // high performance

$ Content = strtolower ($ content); // Convert all to lowercase letters

$ Dangerous_content = strtolower ($ dangerous_content); // Convert all to lower case

IsExists ($ dangerous_content, $ path. "/". $ entry, $ content); // This method is too memory-consuming. I hope some experts can solve this problem.

     }

    }

// Sleep (1 );

   }

  }

 }

$ Fdir-> close ();

}

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

Global $ dangerous;

// Sleep (1 );

Set_time_limit (10 );

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

$ Signature = "signature :";

If (! Empty ($ arr )){

// $ Content = file_get_contents ($ filename); // This has good performance.

$ Content = strtolower ($ content); // Convert all to lowercase letters

$ Error_count = 0;

Foreach ($ arr as $ ){

If (trim ($ )! = ""){

If (strpos ($ content, $ )){

$ Error_count = $ error_count + 1;

$ Signature. = $ ."";

    }

   }

  }

If ($ error_count> 0 ){

// $ Dangerous [] = $ filename;

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

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

} Else {

// Echo "[OK]". $ filename. "<br/> ";

  }

 }

}
