Search all files in directory PHP-CodePudding

I'm trying to search all of the files in a directory instead of one, but I don't know what to use to do that.

results.php:

<?php
// error_reporting(E_ERROR | E_PARSE);
$file = 'db/test.txt';
$searchfor = $_GET['q'];
if (!$_GET['q']) { // returns this if query is empty
     echo "Search something.";
}
else {

// get the file contents, assuming the file to be readable (and exist)
$contents = file_get_contents($file);

// escape special characters in the query
$pattern = preg_quote($searchfor, '/');

// finalise the regular expression, matching the whole line
$pattern = "/^.*$pattern.*\$/m";

// search, and store all matching occurences in $matches
    if (preg_match_all($pattern, $contents, $matches))
    {
    echo "<centerResults</center><br>";
    echo "<pre>";
    echo implode($matches[0]);
    echo "</pre>";
    }
    else
{
   echo "<center>No results</center>";
}
}

I wanted to do something like this on line 3:

$file = 'db/*';

So that it could search through test.txt, and other txt files in that directory.

And i've tried googling, and nothing helpful has come up, any help?

Ther is function called glob it accept a required parameter which is the path and it can be a pattern of the files and it return an array of the paths of all the files that match that pattern . in other words , you can use this function with "dir/*.txt" and it is going to return all the files that ar in the dir folder and has the txt extension
