Answer 1

Hi you can use DirectoryIterator

try {
    $dir = './';
    /* @var $Item DirectoryIterator */
    foreach (new DirectoryIterator($dir) as $Item) {
        if($Item->isFile()) {
            echo $Item->getFilename() . "\n";
        }
    }
} catch (Exception $e) {
    echo 'No files Found!<br />';
}

If you want to pass directories recursively: http://php.net/manual/en/class.recursivedirectoryiterator.php

/**
*  function get files 
*  @param $path string = path to fine files in 
*  @param $accept array = array of extensions to accept 
*  @param currentLevel = 0, stopLevel = 0 
*  @return array of madmanFile objects, but you can modify it to 
*  return whatever suits your needs.  
*/

    public static function getFiles( $path = '.', $accept, $currentLevel = 0, $stopLevel = 0){

            $path = trim($path);                    //trim whitespcae if any
            if(substr($path,-1)=='/'){$path = substr($path,0,-1);}  //cutoff the last "/" on path if provided
            $selectedFiles = array();
            try{
                    //ignore these files/folders
                    $ignoreRegexp = "/\.(T|t)rash/";
                    $ignore = array( 'cgi-bin', '.', '..', '.svn');
                    $dh = @opendir( $path );
                    //Loop through the directory
                    while( false !== ( $file = readdir( $dh ) ) ){
                            // Check that this file is not to be ignored
                            if( !in_array( $file, $ignore ) and !preg_match($ignoreRegexp,$file)){
                            $spaces = str_repeat( ' ', ( $currentLevel * 4 ) );
                                    // Its a directory, so we need to keep reading down...
                                    if( is_dir( "$path/$file" ) ){
                                            //merge current selectFiles array with recursion return which is
                                            //another array of selectedFiles

                                            if(in_array($info['extension'], $accept)){
                                                    $selectedFiles[] = new MadmanFile($info['filename'], $info['extension'], MadmanFileManager::getSize($

                                            }//end if in array
                                    }//end if/else is_dir
                            }
                    }//end while
                    closedir( $dh );
                    // Close the directory handle
            }catch (Exception $e){
                    echo 'Caught exception: ',  $e->getMessage(), "\n";
            }

            return $selectedFiles;
    }

Answer 3

You could as others have suggested check every file in the dir, or you could use glob to identify files based on extension.

Answer 4

$dir = "/etc/php5/";

// Open a known directory, and proceed to read its contents

if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
        }
        closedir($dh);
    }
}
