How to remove a variable from a function?

Question

PHP

Hello, I already created a similar topic, but the question was not very clear, now I decided to describe the problem more meaningfully, since I can’t solve it myself.
Such a task. There is a star rating script. Asterisks and a numeric rating value are displayed. I have a variable that holds a value. The task such needs to be deduced, only this variable. An example picture, there is a text line where information is displayed: Rating: 3.4, you need to display only the number "3.4". Presumably the value of the number is stored in the $count variable.

To display the rating, the _drawrating.php file is connected, and the line <?php echo rating_bar('id1',''); ?> ,id1 is the vote id stored in the database,
The script was taken from here: coderhs.com/archive/unratajax
What should be written in this line <?php echo rating_bar('id1',''); ?> to display not the entire rating, but only the number?
The _drawrating.php file code itself:

<?php
/*
Page:           _drawrating.php
Created:        Aug 2006

The function that draws the rating bar.

function rating_bar($id,$units='',$static='') { 
 
require('_config-rating.php'); // get the db connection info
    
//set some variables
$ip = $_SERVER['REMOTE_ADDR'];
if (!$units) {$units = 10;}
if (!$static) {$static = FALSE;}
 
// get votes, values, ips for the current rating bar
$query=mysql_query("SELECT total_votes, total_value, used_ips FROM $rating_dbname.$rating_tableName WHERE id='$id' ")or die(" Error: ".mysql_error());
 
 
// insert the id in the DB if it doesn't exist already

if (mysql_num_rows($query) == 0) {
$sql = "INSERT INTO $rating_dbname.$rating_tableName (`id`,`total_votes`, `total_value`, `used_ips`) VALUES ('$id', '0', '0', '')";
$result = mysql_query($sql);
}
 
$numbers=mysql_fetch_assoc($query);
 
 
if ($numbers['total_votes'] < 1) {
    $count = 0;
} else {
    $count=$numbers['total_votes']; //how many votes total
}
$current_rating=$numbers['total_value']; //total number of rating added together and stored
$tense=($count==1) ? "vote" : "votes"; //plural form votes/vote
 
// determine whether the user has voted, so we know how to draw the ul/li
$voted=mysql_num_rows(mysql_query("SELECT used_ips FROM $rating_dbname.$rating_tableName WHERE used_ips LIKE '%".$ip."%' AND id='".$id."' ")); 
 
// now draw the rating bar
$rating_width = @number_format($current_rating/$count,2)*$rating_unitwidth;
$rating1 = @number_format($current_rating/$count,1);
$rating2 = @number_format($current_rating/$count,2);
 
 
if ($static == 'static') {
 
        $static_rater = array();
        $static_rater[] .= "\n".'<div class="ratingblock">';

        $static_rater[] .= '<li class="current-rating" style="width:'.$rating_width.'px;">Currently '.$rating2.'/'.$units.'</li>';
        $static_rater[] .= '</ul>';
        $static_rater[] .= '<p class="voted">'.$id.'. Rating: <strong> '.$rating1.'</strong>/'.$units.' ('.$count.' '.$tense.' cast) <em>This is \'static\'.</em></p>';
        $static_rater[] .= '</div>';
        $static_rater[] .= '</div>'."\n\n";
 
        return join("\n", $static_rater);
 
 
} else {
 
      $rater ='';
      $rater.='<div class="ratingblock">';
 
      $rater.='<div id="unit_long'.$id.'">';
      $rater.='  <ul id="unit_ul'.$id.'" class="unit-rating" style="width:'.$rating_unitwidth*$units.'px;">';
      $rater.='     <li class="current-rating" style="width:'.$rating_width.'px;">Currently '.$rating2.'/'.$units.'</li>';
 
      for ($ncount = 1; $ncount <= $units; $ncount++) { // loop from 1 to the number of units
           if(!$voted) { // if the user hasn't yet voted, draw the voting stars
              $rater.='<li><a href="db.php?j='.$ncount.'&amp;q='.$id.'&amp;t='.$ip.'&amp;c='.$units.'" title="'.$ncount.' out of '.$units.'" class="r'.$ncount.'-unit rater" rel="nofollow">'.$ncount.'</a></li>';
           }
      }
      $ncount=0; // resets the count
 
      $rater.='  </ul>';
      $rater.='  <p';
      if($voted){ $rater.=' class="voted"'; }
  
       $rater.='>Рейтинг машины: '.$rating1.' <strong class="rate-cifre">('.$count.'<strong class="ratelike"></strong>)</strong>';
      $rater.='  </p>';
      $rater.='</div>';
      $rater.='</div>';
      return $rater;
 }
}
?>

I will add: - It is necessary that the star rating be in one place, and the numerical value should still display the rating in another place.

Answer 1

Remove everything you don't need except $rating1 from this line. HTML formatting can be left for beauty if you wish.

$static_rater[] .= '<p class="voted">'.$id.'. Rating: <strong> '.$rating1.'</strong>/'.$units.' ('.$count.' '.$tense.' cast) <em>This is \'static\'.</em></p>';

Answer 2

The solution to my problem:
After the rating_bar function, you need to insert the function below, in the _drawrating.php file, this code:

function rating_bar_number($id,$units='',$static='') { 
 
  require_once('_config-rating.php'); // get the db connection info
 
  // get votes, values, ips for the current rating bar
  $query=mysql_query("SELECT total_votes, total_value, used_ips FROM $rating_dbname.$rating_tableName WHERE id='$id' ")or die(" Error: ".mysql_error());
   
   
  // insert the id in the DB if it doesn't exist already
  // see: http://www.masugadesign.com/the-lab/scripts/unobtrusive-ajax-star-rating-bar/#comment-121
  if (mysql_num_rows($query) == 0) {
    $sql = "INSERT INTO $rating_dbname.$rating_tableName (`id`,`total_votes`, `total_value`, `used_ips`) VALUES ('$id', '0', '0', '')";
    $result = mysql_query($sql);
  }
   
  $numbers=mysql_fetch_assoc($query);
   
   
  if ($numbers['total_votes'] < 1) {
      $count = 0;
  } else {
      $count=$numbers['total_votes']; //how many votes total
  }
  $current_rating=$numbers['total_value']; //total number of rating added together and stored
 
  $rating1 = @number_format($current_rating/$count,1);
  return $rating1;
}

And where you need only a number, call like this:
And where is the main rating:
<?php echo rating_bar('id1',''); ?>
