how do I not get a random 0 ?

I need to get two random numbers from 1 to 57 say, how do I not get the 0.

I have a paragraph of text and am trying to select two numbers but every now and then I get a 0 which as the numbers start from 1 there is no word for 0. the code I have is as follows it's a bit messy. 🙂

<?php
$text = "A jukebox with one song is unlikely to be popular (except perhaps in some very, very scary bars), so pretty soon we'll have to start thinking about producing a catalog of available songs and a playlist of songs waiting to be played. Both of these are containers: objects that hold references to one or more other objects.";

$word_count = count_words($text);


//echo " - $word_count - ";

{

srand(time());
// the random number 1 to 57
for ($i=1; $i < $word_count; $i++)
{
// enter the max number as %xx

  $random = (rand()%$word_count);
  $slot[] = $random;
}

print(" Enter the $slot[0]");
print(" and the $slot[1]");
print (" word in the paragraph located at www.XXXXXXXXX.com/validate.html");

}

?>
Word 1 = 
Word 2 =
Confirm
 
<?
// print("<td width=\"33%\"><center>$slot[2]</td>");
// if($slot[0] == $slot[1] && $slot[0] == $slot[2])
{
print("If confirm ok the show this - $word_count - ");
// exit;
}
?>

<?php

function count_words($string) {

$word_count = 0;
$string = eregi_replace(" +", " ", $string);
$string = explode(" ", $string);

while (list(, $word) = each ($string)) {
    if (eregi("[0-9A-Za-zÀ-ÖØ-öø-ÿ]", $word)) {
        $word_count++;
    }
}
return($word_count);

}

fixed it I think

replace $random = (rand()%$word_count);

with $random = rand(1,$word_count);
