PHP foreach if/else Issue

Give this a try?

<?php

    $result = mysql_query("SELECT * FROM ap_form_5 WHERE element_1='19'") or die(mysql_error());
    $num_rows = mysql_num_rows($result);

    while($profile_rows = mysql_fetch_array($result)) {

        $total_ratings_this_loop = 0; // empty this before looping
        $ratings[1]= $profile_rows['element_4']; // assuming that this field contains 1 star ratings for this product
        $ratings[2]= $profile_rows['element_5']; // assuming that this field contains 2 star ratings for this product
        $ratings[3]= $profile_rows['element_6']; // assuming that this field contains 3 star ratings for this product
        $ratings[4]= $profile_rows['element_7']; // assuming that this field contains 4 star ratings for this product
        $ratings[5]= $profile_rows['element_8']; // assuming that this field contains 5 star ratings for this product

        $total_ratings_this_loop = array_sum($ratings); // takes all of the ratings for this product and totals them from inside the array

        $overalladd  = $feature1 + $feature2 + $feature3 + $feature4 + $feature5;

        echo "Product ID: 19, has the following ratings<br />";

        $i = 1; // empty this before looping
        foreach($ratings as $rating_count){
            echo $i." star, Rating count: ".$rating.",Percentage:".perc($total_ratings_this_loop,$rating)."%<br />";
            $i ++;
        }   

    }

 ?>

Replace your code with below code and check :

$myArray = str_split($ratingsbar);
$newArray = array_count_values($myArray);

foreach ($myArray as $key => $value) {

$reviews_percentage = round($value/$num_rows*100);

if (array_key_exists("1",$myArray)) {


echo "$key - <strong>$value</strong> as a percent its : $reviews_percentage <br />";   
}

else {

echo "1 - <strong>0</strong> as a percent its : 0 <br />"; 
}

if (array_key_exists("2",$myArray)) {

echo "$key - <strong>$value</strong> as a percent its : $reviews_percentage <br />"; 
}

else {

echo "2 - <strong>0</strong> as a percent its : 0 <br />"; 
}

if (array_key_exists("3",$myArray)) {

echo "$key - <strong>$value</strong> as a percent its : $reviews_percentage <br />"; 
}

else {

echo "3 - <strong>0</strong> as a percent its : 0 <br />"; 
}
if (array_key_exists("4",$myArray)) {

echo "$key - <strong>$value</strong> as a percent its : $reviews_percentage <br />"; 

}

else {

echo "4 - <strong>0</strong> as a percent its : 0 <br />"; 
}

if (array_key_exists("5",$myArray)) {

echo "$key - <strong>$value</strong> as a percent its : $reviews_percentage <br />"; 
}

else {

echo "5 - <strong>0</strong> as a percent its : 0 <br />"; 
}


}

What I'm trying to do is count the number of reviews based on the score.

Please show us the database structure filled with minimized example data, and tell us what is your expected result according to that data.

OK, if you would like to create something like this:

then I demostrate, how I would do it, because I still does not understand your logic.

votes table (this means user U voted on product P with S stars):
user_id |  product_id    | star
      1           1         5   
      2           1         5
      3           1         4
      4           1         1

sql query for total votes on product 1 is

SELECT star,COUNT(*) as C 
FROM votes 
WHERE product_id=1 
GROUP BY star 

the result of this is

star    C
1       1
4       1
5       2

to write it out:

$rs = mysql_query("");//put query here
$stars_count = array();
$star_sum = 0;
while($r = mysql_fetch_assoc($rs))
{
  $stars_count[$r['star']] = $r['C'];
  $star_sum += $r['C'];
}
for($i=5;$i>=1;$i--)
  echo "Product 1 was voted $i star: ".
     (isset($stars_count[$i])? round($stars_count[$i]/$star_sum*100)."%":"0%").
     " (".( isset($stars_count[$i])? $stars_count[$i] : 0 ).")<br>";

result:

Product 1 was voted 5 star: 50% (2)
Product 1 was voted 4 star: 25% (1)
Product 1 was voted 3 star: 0% (0)
Product 1 was voted 2 star: 0% (0)
Product 1 was voted 1 star: 25% (1)
