Directory search script

[Dustin Lee]

Hello all, I have been working on a search script for my site. I currently have everything upload to a directory so a directory, so I'm stuck there.My main problem is, I can only set it to search only one directory at any time, and any attempts I have to have it search multiples at once is stopped with errors.

<?phpinclude "header.php";$upload_dir = "visual/files/";$handle = opendir($upload_dir);$name = str_replace(" ","",$name);if($_GET[s]) {	while ($file = readdir($handle)) {		if(!is_dir($file) && !is_link($file)) {			if(preg_match("/".$_GET[s]."/i", $file)) {				$filelist .= "<a href='$upload_dir$file'><b>$file</b></a><br />";			}		}	}}if($filelist) {	echo "<b>Search results:</b><br /><br />";	echo $filelist;} else {	echo "<b>No results found!</b>";}include "footer.php";?>

I have looked at a few methods, but none seem to work.How would I go about having it simultaneously search several different directories?

You might want to consider using grep, invoked with backticks, system, or exec. Be sure to sanitize any search inputs.grep -ri 'search string' * That would be to search for 'search string' within files. To search for files by name, you could use find - it's another command under Linuxfind -name 'search string'orPHP's glob function, which I'm not sure would work in that way.

I don't know if you are still looking in to PHP directory functions, but I have a script I made like 2-3 years ago (back when I was a bad coder) that works well. I would not suggest using the script as it probably is inefficient or may abuse resources (there's a reason that you need a password ). Anyway it uses scandir(), then it looks through that list testing if each element in the array is a file, or directory. If its a directory then it appends that to a list of directories to loop through when the current is finished. This might not work well if you don't have a small simple site, but again use the methods to rewrite your own.

<?phpsession_start();if(!isset($_SESSION['tmp']['auth'])){  if($_SERVER['QUERY_STRING'] == 'clonetrooper9494')    $_SESSION['tmp']['auth'] = true;  else  {    echo 'Please enter in the correct code to continue searching.<br>';    echo '(Type in the correct code after the ? in the url)';    exit;  }}$searchterm = urldecode($_SERVER['QUERY_STRING']);$base_dir = $_SERVER['DOCUMENT_ROOT'];//$base_dir = getcwd();$dir = '/home/clonedro/';//$base_dir.'/';$file = scandir($dir);$search_limit = 101;$folders[0] = 'null';$found[0] = 'Found:';foreach($file as $key => $name){  if(count($found) < $search_limit && $name != '.' && $name != '..')  {//    echo $dir.$name.' <- Starting';    if(is_dir($dir.$name))    {      array_push($folders,$dir.$name);//      echo ' <- Is a Folder<br>';    }    else    {//      echo ' <- Is a File<br>';      if(strpos(file_get_contents($dir.$name),$searchterm) !== false || strpos($name,$searchterm) !== false)      {        array_push($found,$dir.$name);        echo $dir.$name.' <- Found Search Term<br>';      }    }  }}while(count($folders) > 1)foreach($folders as $key22 => $name22){if($name22 != 'null' && $name22 != ''){  $file = scandir($name22);foreach($file as $key => $name){  if(count($found) < $search_limit && $name != '.' && $name != '..')  {//    echo $name22.'/'.$name.' <- Starting';    if(is_dir($name22.'/'.$name))    {      array_push($folders,$name22.'/'.$name);//      echo ' <- Is a Folder<br>';    }    else    {//      echo ' <- Is a File<br>';      if(strpos(file_get_contents($name22.'/'.$name),$searchterm) !== false || strpos($name,$searchterm) !== false)      {        array_push($found,$name22.'/'.$name);        echo $name22.'/'.$name.' <- Found Search Term<br>';      }    }  }}}  unset($folders[$key22]);}?>

I'm not familiar with that code at all - I'm more of a web design type of person.I'll look into it, but this is for website directory searching, right? A few people thought I was talking about searching certain areas of my computer's HDD.

That's a lot more complicated that I thought it would be... There is no easy want to define two+ separate directories?Looking through some code this guy has, I see something close to what I need but not entirely.

$FILE_EXTS  = array('.psd','.jpg');

That is kind of what I need, but more so, not.

$upload_dir = "audio/q/";

I just need that to look in: audio/q, audio/x, audio/files, and visual/files, but array (which I assumed meant variety - told you I'm a newb) doesn't seem to work, I'd make something like:

$upload_dir  = array('audio/files','audio/x');

and it would just return errors, all though, having just one works fine.Is there really no way to easily do this without pretty much rewriting my week-long code. I'm slow and uneducated with code as it is, something more advances could take me months.

Use http://us2.php.net/manual/en/function.glob.php to find files by name. It will give you an array and then you can use http://us2.php.net/manual/en/function.preg-grep.php to search the array.The scandir_through function is from the first link.

<?phpfunction scandir_through($dir){	$items = glob($dir . '/*');	for ($i = 0; $i < count($items); $i++) {		if (is_dir($items[$i])) {			$add = glob($items[$i] . '/*');			$items = array_merge($items, $add);		}	}	return $items;}$aJS=scandir_through('thedirectory');$aResults=preg_grep('/searchstring/',$aJS);var_dump($aResults);?>

Equivalent code using a command (probably won't work on a Windows machine). This is probably faster than the above.

<?php$sString=escapeshellarg('*convert*');$sOutput=`find js/* -name $sString`;var_dump($sOutput);?>
