Question

i have:

@ = 1
# = 0,5
% = 0

max = 10

for example if i have: 3 then should show me:

@@@$$$$$$$

if i have 3,5 :

@@@#$$$$$$

etc

if i have 3,99 then = 3,5
if i have 3,49 then = 3,0

etc

how can i use this with foreach or for?

for whole number i can make:

$number = 8;
$one = 10 - $number;
$three = 0 + $number;

and

for($i=1;$i <= $one){
  echo "@";
}

for($i=1;$i <= $three){
  echo "$";
}

but how is the best solution if $number = 3,57

If I’ve understood what you’re after, this should do what you want:

<?php

function printItOut($number) {
    $s = '';
    for ($i = 0; $i < 10; $i++) {
        if ($i < $number%10) {
            $s .= '@';
        } else if ($i < ($number+0.5)%10) {
            $s .= '#';
        } else {
            $s .= '$';
        }
    }
    return $s;
}


echo printItOut(3.49), "\n";
echo printItOut(3.5), "\n";
echo printItOut(3.99), "\n";
echo printItOut(4), "\n";

Outputs:

@@@$$$$$$$
@@@#$$$$$$
@@@#$$$$$$
@@@@$$$$$$

Inside the for loop, I using the modulus operator to find the integer remainder of dividing $number by 10. So 3%10 gives a result of 3, 3.49%10 also results in 3.

In the first ‘else if’ block, I’m checking whether the number is 0.5 or more, since (3.49+0.5) is 3.99, and 3.99%10 is 3; but 3.5+0.5 is 4, and 4%10 is 4.
