I am working on a quiz app image 1 shows the index.php page image 2 shows the first question image 3 shows the second question image 4 shows the third question image 5 shows the result after completing the quiz image 6 shows the database 'quizzer' and its tables image 7 shows the 'questions' table image 8 shows the 'choices' table THIS LINK CONTAIN ALL THE CODE (and images) I HAVE DONE SO FAR https://www.mediafire.com/folder/g5ao7f5q0fe6y/quiz 1.Now my question is how to select the question RANDOMLY from 'questions' table along with 'choices' (by adding code to the existing file or create a new one). 2.If user refresh/reload the page before starting ('Start Quiz') or click 'Take Again' after finishing the quiz, the question should appear randomly. 3.Basically I want to change the order of question appearing in the browser each time I refresh. 4.My work so far is mentioned above.........Please help me with this "RANDOM" problem !! P.S - Will it be possible, by creating a random function in PHP which will check for repeat questions in a session and check for the 'id' of the question and if it is new display it on the page. If so what should I do and if no then how to do?

Hi in my code below, echo $body; outputs the link to every song in my $SongsFolder. How can I make it echo only one link and that link is the song the $Shuffle chose? I know I have array but is there a way to get around it? Anything I should change up? <?php function fooFucker($url) { $a = join('/', array_map('urlencode', explode('/', $url))); return str_replace('+', '%20', $a); } $SongsFolder = "songs"; header("Content-Type: audio/x-mpegurl"); $body = ''; $Songs = glob($SongsFolder."/*.mp3"); shuffle($Songs); $first = 0; foreach($Songs as $Song) { $SongPath = pathinfo($Song); if ($first != 0) { $body .= "\n"; } $first = 1; $body .= "http://".$_SERVER['HTTP_HOST'].fooFucker(dirname($_SERVER['PHP_SELF']))."/".fooFucker($SongsFolder)."/".fooFucker($SongPath['basename']); } header('Content-Length: ' . strlen($body)); echo $body; ?>

So in my code below I have a script where it shuffles through .mp3 in a folder. How can I make the line below know which song the shuffle() has picked? $ThisFileInfo = $getID3->analyze($Songs[0]); <?php require_once('/home/manveers94/public_html/getID3-1.9.7/getid3/getid3.php'); $getID3 = new getID3; function fooFucker($url) { $a = join('/', array_map('urlencode', explode('/', $url))); return str_replace('+', '%20', $a); } $SongsFolder = "songs"; header("Content-Type: audio/x-mpegurl"); $body = ''; $Songs = glob($SongsFolder."/*.mp3"); shuffle($Songs); $first = 0; foreach($Songs as $Song) { $SongPath = pathinfo($Song); if ($first != 0) { $body .= "\n"; } $first = 1; $body .= "http://".$_SERVER['HTTP_HOST'].fooFucker(dirname($_SERVER['PHP_SELF']))."/".fooFucker($SongsFolder)."/".fooFucker($SongPath['basename']); } set_time_limit(30); $ThisFileInfo = $getID3->analyze($Songs[0]); getid3_lib::CopyTagsToComments($ThisFileInfo); $body .= 'File name: '.$ThisFileInfo['filenamepath'].'<br>'; $body .= 'Artist: '.(!empty($ThisFileInfo['comments_html']['artist']) ? implode('<BR>', $ThisFileInfo['comments_html']['artist']) : ' ').'<br>'; $body .= 'Title: '.(!empty($ThisFileInfo['comments_html']['title']) ? implode('<BR>', $ThisFileInfo['comments_html']['title']) : ' ').'<br>'; $body .= 'Bitrate: '.(!empty($ThisFileInfo['audio']['bitrate']) ? round($ThisFileInfo['audio']['bitrate'] / 1000).' kbps' : ' ').'<br>'; $body .= 'Play time: '.(!empty($ThisFileInfo['playtime_string']) ? $ThisFileInfo['playtime_string'] : ' ').'<br>'; header('Content-Length: ' . strlen($body)); echo $body; ?>

Hi I have an .m3u playlist file on my server, it has links to different songs on my server. The .m3u playlist streams all the music. The thing I want the .m3u file to do is shuffle the music instead of going in the same order. I've been using this method to do it but it doesn't work. Any other ways or something wrong with my code? <?php $playlist = “/DONTFUCKWITHME/playlist.m3u"; if ($_SERVER['PATH_INFO'] == "/playlist.m3u") { # This a request for the actual playlist. playlist(); } else { # Fall through to end of script and display # the player HTML. } function playlist() { header("Content-type: audio/mpeg"); # Needed for PHP versions OLDER than 4.2.0 only. # If your host still has PHP older than 4.2.0, shame on them. # Find a better web host. srand(make_seed()); # Fetch our list of songs from a file. $songs = file($playlist); shuffle($songs); # Now output the URLs in random order. foreach ($songs as $song) { # Remove newline and any other leading and trailing # whitespace from URL of song. $song = trim($song); echo "$song\n"; } # Now exit before any HTML is produced. exit(0); } # Needed only for very old versions of PHP, # see srand call earlier. function make_seed() { list($usec, $sec) = explode(' ', microtime()); return (float) $sec + ((float) $usec * 100000); } ?> <html> <head> <title>MP3s Playing in Random Order</title> </head> <body> <h1 align="center">MP3s Playing in Random Order</h1> <embed src="/examples/randomsongs.php/playlist.m3u" width="0" height="0" autostart="true" type="audio/mpeg" loop="true"/> </body> </html>

So this is my 2nd PHP class ever. And this right here is part of my final. I'm sure you all know what the "shuffle" function does. What I thought I could make it do was randomize a bunch of echoes I have. Is that possible? Any help would be greatly appreciated. KCCO!

Hey guys i've got a rookie question. How do i shuffle an array then display each number in the array using implode? Heres my code. $maximum_integer = strip_tags(trim($_REQUEST['maximum_integer'])); $range = range(0,$maximum_integer); $range_randomized[] = shuffle($range); $random_range_imploded = implode(', ', $range_randomized); print $random_range_imploded; it just keeps displaying '1'.... Thanks!
