Question

I have a script that gets a string from a config file and based on that string grabs the file names of a folder.

I now only need the iso files. Not sure if the best way is to check for the .iso string or is there another method?

<?php
    // Grab the contents of the "current.conf" file, removing any linebreaks.
    $dirPath = trim(file_get_contents('current.conf')).'/';

    $fileList = scandir($dirPath);

    if(is_array($fileList)) {
        foreach($fileList as $file) {
//could replace the below if statement to only proceed if the .iso string is present. But I am worried there could be issues with this.


         if ($file != "." and $file != ".." and $file != "index.php")
{

            echo "<br/><a href='". $dirPath.$file."'>" .$file."</a>\n";
    }
        } 
    }
    else echo $dirPath.' cound not be scanned.';
?>

Answer 1

If you only need the files with an extension of .iso, then why not use:

glob($dirPath.’/*.iso’);

rather than scandir()
