Why can't this be done???

[stweaker]

I don't understand why I can't get a random quote everytime I call $quotes[$r]???

It shows the same quote... I refresh it shows 2 more of the same... I want it to show to different quotes on every refresh

Is there anyway I can set the random array to reset everytime it's echo into a simple var or something??? This is driving me crazy!

<?php

$quotes[] = 'first quote';
$quotes[] = 'second quote';
$quotes[] = 'etc...';

srand ((double) microtime() * 1000000);
$r = rand(0,count($quotes)-1);

echo ($quotes[$r]);
echo ($quotes[$r]);

?>

<?php

$quotes[] = 'first quote';
$quotes[] = 'second quote';
$quotes[] = 'etc...';

function randomize($or = '')
{
  $r = rand(0, count($quotes)-1);
  if($r == $or)
  {
    randomize($r);
  }
  return $quotes[$r];
}

$quote = ranzomize();
?>

Weird that code gives me a 500 Internal Server Error...

it's template code, not literal. I don't expect it to work. You could use something like that though.

This does work:

session_id('randomQuote');
session_start();

$sr = (isset($_SESSION['qid']))?$_SESSION['qid']:'';

$quotes = array(
	'1... 2.... 3.... 4.... 5....',
	'So the combination is 1 2 3 4 5',
	'That\'s the kind of combination an idiot would put on his luggage!',
	'Did we get the combination?',
	'Yes sir.  It\'s 1 2 3 4 5',
	'Wow!  That\'s the same combination I have on my luggage!',
	'Ludacris Speed!  NOW!!!'
);

$max = count($quotes)-1;

function randomize($or='')
{
	global $max, $quotes, $sr;
  $r = rand(0, $max);
  if( ($r == $or) || ($r == $sr) )
  {
    randomize($r);
  }
	$_SESSION['qid'] = $r;
  return $quotes[$r];
}

$quote = randomize();

echo $quote;

Thx. Brett I tried that but unfortunately it display what I had before...

echo $quote;
echo $quote;

Displays...

So the combination is 1 2 3 4 5 So the combination is 1 2 3 4 5

Instead of say...

So the combination is 1 2 3 4 5 Yes sir. It\'s 1 2 3 4 5

Well duh... you're not getting a new quote, you're echoing the same variable.

If you want it to get another quote, just call the function again. You can't just call a variable and expect it to give you a new value. You have to do it one of two ways:

Example 1:

$quote = randomize();
$quote2 = randomize();

Example 2:

echo randomize();
echo randomize();

Some other possibilities:

function random_array_item_1($array) 
{ 
    return $array[array_rand($array)];
}

function random_array_item_2($array)
{
    return $array[mt_rand(0, count($array) - 1)];
}

function random_array_item_3($array)
{
    shuffle($array);
    return $array[0];
}

$quotes = array( 
    '1... 2.... 3.... 4.... 5....', 
    'So the combination is 1 2 3 4 5', 
    'That\'s the kind of combination an idiot would put on his luggage!', 
    'Did we get the combination?', 
    'Yes sir.  It\'s 1 2 3 4 5', 
    'Wow!  That\'s the same combination I have on my luggage!', 
    'Ludacris Speed!  NOW!!!' 
); 

echo random_array_item_1($quotes) . '<br />'; 
echo random_array_item_2($quotes) . '<br />'; 
echo random_array_item_3($quotes) . '<br />';

another simple way would be

$quote = array('val1', 'val2', 'val3', 'val4', 'val5');
$size = sizeof($quote) -1;

print $quote[rand(0, $size)];
print $quote[rand(0, $size)];

But that doesn't ensure that you'd get two different quotes, you still have the possibility for repeat.

@:
Seems a little much for something so simple... 3 different functions for generating 3 quotes... why not just use a recursive function like me?

I was just showing some templates, like you. They don't have to be in functions, or they can be made recusive in functions, or they can be done with as the poster wishes. Like calling one thrice, or one twice and another once, or one once and another twice...I don't really give a shit how he uses them, if at all.
