PHP array to stars -

i have array values: 7.09, 5.63 , 5.35 , ...

i'm rounding them 0.5 with:

round(x * 2) / 2; 

now have 7, 6, 5.5

how can make stars these? max stars 5. need make 5 stars = highest array value, what's then? sorry bad english. don't know should do.

7 - 5 stars

6 - 4.5 stars

5.5 - 4 stars

$marray = array(8,2,5,1);   $biggestnumber = max($marray);   foreach($marray $index => $star){     $percent =  $star / $biggestnumber * 100;     $mfinalarray[$index]['number'] = $star;     $mfinalarray[$index]['stars'] = $percent / 100 * 5; }  print_r($mfinalarray); 

output :

array (     [0] => array         (             [number] => 8             [stars] => 5         )      [1] => array         (             [number] => 2             [stars] => 1.25         )      [2] => array         (             [number] => 5             [stars] => 3.125         )      [3] => array         (             [number] => 1             [stars] => 0.625         )  ) 

also if want round numbers, change last line

$mfinalarray[$index]['stars'] = $percent / 100 * 5;

to

$mfinalarray[$index]['stars'] = round($percent / 100 * 5);

example output using round :

array (     [0] => array         (             [number] => 8             [stars] => 5         )      [1] => array         (             [number] => 2             [stars] => 1         )      [2] => array         (             [number] => 5             [stars] => 3         )      [3] => array         (             [number] => 1             [stars] => 1         )  )
