Question about pulling random items

I'm trying to pull a random number of keywords from a file...and I just can get it. Basically what I have is a list of keywords, on per line, in a text file, and I need to pull out x number of those keywords on the fly. I don't have access to a database, hence the text file.

So what I have so far is:

<?
$f1 = file("keywords.txt");
$max = "10";
$min = "5";
$item = array_rand ($f1);
$toshow = rand($max,$min);
$i = 1;
while ($i < $toshow){

echo $item[$i];

$i = $i+1;

};
?>

Code (markup):

But obviously this isn't working or I wouldn't be here... Any help?

Thanks in advance,

Mike

 

Use array_rand(). It's much easier and you can specify the number of items you want to pull.

 

Is it possible that you could give me an example...I really seem to be struggling with this. thanks in advance, Mike

 

Displays between 2 and 6 random lines from test.txt:

$keyword_array = file('test.txt');

$min = 2;

$max = 6;

$num_keywords = rand($min, $max);

$rand_keyword_keys = array_rand($keyword_array, $num_keywords);

foreach ($rand_keyword_keys as $key => $value) {
	echo $keyword_array[$value] . '<br />';		
}
