Simple PHP local directory text file search

I have "IceWarp" running on my email server and I need a simple php script that will search selected directories full of text files and return results as text file links (links to the text file)

I know it sounds simple, but I can't seem to find anything of use that is not a search engine (google) or MySQL based solution. I cannot install MySQL so database indexing is out...

I only need the script to check text files for word matches and display them.
It would be nice if it had a cache but it is not needed.

The script needs to be able to check multiple directories and subdirectories.
I can create this in about 5 minutes in VBScript, but unfortunately I know nothing of php and my hands are tied on what to use.

Before someone starts posting suggestions, what version of PHP and what platform (unix, windows, etc)?

windows... it's running the latest versionof IceWarp.. as far as PHP I am not sure most lilkey the latest version (or the most recent to the latest)

MMDeveloper

this runs fine on a windows server we have at work here.

it recursively searches "C:\Inetput\wwwroot" for all .txt files containing the case-insensitive string "te"

<?php
$searchFiles = new searchFiles();
$searchFiles->doSearch('C:\Inetpub\wwwroot', "te");
print_r($searchFiles->results);
 
class searchFiles {
 
	private $baseDir		= "";
	private $stringMatch		= "";
	public  $results		= array();
 
	public function searchFiles() {
		//sit pretty
	}
 
	public function doSearch($baseDir, $stringMatch) {
		$this->baseDir = $baseDir;
		$this->stringMatch = $stringMatch;
 
		$this->traverseDirectory($baseDir);
	}
 
	private function traverseDirectory($dir) {
		$ignore = array (
				".",
				".."
			);
		$d = dir($dir);
		while (($entry = $d->read()) !== false) {
			if (!in_array($entry, $ignore)) {
				$ePath = $d->path . "\\" . $entry;
				if (is_file($entry)) {
 
					if (eregi(".txt", $entry)) {
						$this->searchFile($ePath);
					}
				}
				elseif (is_dir($entry)) {
					$this->traverseDirectory($ePath);
				}
				else {}
			}
		}
	}
 
	private function searchFile($file) {
		$fp = fopen($file, "r");
		$contents = fread($fp, filesize($file));
		fclose($fp);
 
		if (eregi($this->stringMatch, $contents)) {
			$this->results[] = $file;
		} else {}
		unset($contents);
	}
}
?>

it returned..

Array ( )

MMDeveloper

what did you replace this line with

$searchFiles->doSearch('C:\Inetpub\wwwroot', "te");

EGormly

ASKER

just a folder that had some text files.. I changed "te" to "the" to make sure I would get a result.

$searchFiles->doSearch('C:\Program Files\ProgramMaker\MailServer\mail\mywebsite.com\user\inbox', "the");

That folder is valid and was copied directly from explorer toolbar.
Is it an execute issue? I would imagine an error would return an error and a result would have beem formatted differently.

Just coming back as :
Array ( )

and nothing else is extremley odd.. no?

I also tried changing it to a new folder with two test text files both containing the key word.
$searchFiles->doSearch('C:\inbox', "the");

and I got the same result.

MMDeveloper

ok I put some debugging info in this one... see what this one says.

can you paste the output here (or attach as a .txt file)?

ok I see what happened... below is a fixed version...

I had an idea during making the last half of my original code and failed to update a function to reflect the code change.

<?php
class searchFiles {

                //sit pretty
        }
 
        public function doSearch($baseDir, $stringMatch) {
                $this->baseDir = $baseDir;
                $this->stringMatch = $stringMatch;
 
                $this->traverseDirectory($baseDir);
        }

There are definately many "the" in the text files.
I also changed it to reflect other manually found (and placed) words and I don't get anything.

Also, there is a subfolder called "subfolder" that has text files with the search word and that doesn't show like the root folder does.

Note: i get these reults without a subfolder:

what had happened was originally it was using

is_file($entry) however I later built a 'path' and called it $ePath but failed ot update the 2 if statements to use ePath, so it would find the first level files/folders but wouldn't traverse them or search them.

I dont know what the deal is with me today, I usually nail it on the head on the first or second go'round. I'm so ashamed, heh.
