Rating System | Display the ratings from a single variable

Question

So, my question is very strait forward, I have a single variable, per say 4, and I need to translate it to some kind of rating, very simple ( it goes from 1 to 5 ) without half stars or anything.

I need to display a rating out of a number which goes from one to five, so if I have 1 I will have a star, if I have 5 I will have five stars. I can do a for loop and display the images, but I also need to show the empty ( not rated ) star. I don't need any functionality to it, so you cannot actually rate, just show the ratings.

So because anyone is asking what I've tried, I haven't tried anything because I don't know where to begin.

I could do this to show a number of stars based on the variable I have ( which is a number from 1 -> 5 ):

<?php

$ratings = 3;

for( $i = 1; $i <= $ratings; $i++)
echo '<img src="some_image.png" />';

?>

This would be it, but what should I do for the non-rated starts, how do I display the rest of the empty stars till five ?

Answer 1

you can do an nested for loop like so:

$tranStars;

for($i=0;$i<5;$i++){
  if($i==0){
    for($j=0;$j<$rating;$j++){
      echo "<img src='yourFullStars.png'/>";
      $tranStars=$j;
    }
    $i=$tranStars;
  }
  echo "<img src='yourEmptyStars.png'/>";
}

or you could do two separate for loops:

for($i=0;$i<$rating;$i++){
  echo "<img src='yourFullStars.png'/>";
}
for($i=0;$i<5-$rating;$i++){
  echo "<img src='yourEmptyStars.png'/>";
}

... or any number of things, really.
