Count the percentage of the number of the current iteration in a foreach loop

Question

I am trying to build up a script that gets the current percentage of the iteration of a loop.

I have :

Answer 1

Firstly, you have to get the total amount of iterations. count() helps in this case.

<?php
    $counter = 0;
    $total = count($yourArray);

    // ...
      // inside the loop
      $counter++;
      $percentage = $counter/$total;

Live example

Converting 0.xx to x % is left as an exercise for the reader.

Answer 2

You can do exactly what are you asking in this way

$counter = 0;
$length  = count($array);

foreach ($array as $value) {

$counter=$counter+1;
for ($stepvvx = 10; $stepvvx <= 100; $stepvvx=$stepvvx+10)
    {
if ($counter==intval(($length*$stepvvx)/100)){
    echo "<br>$stepvvx %";
}

# do your task here

}

Answer 3

Store the total length of the array in a variable and use that to calculate the percentage. Watch that you prefix your variables with $. Also, you might want to name your variables more appropriately—an array isn't a key.

$counter = 0;
$length  = count($array);

foreach ($array as $value) {
    $counter++;
    $percentage = $counter / $length;
}

Answer 4

you need to do ($total/$iterations) * $counter like this code:

 $counter = 0;
 $total = 100;
 $iterations = count($key);

 foreach($key as value) {
      $counter++;
      $percentage = (($total/$iterations) * $counter)/100;
 }

Answer 5

To calculate percentage, you take the current and divide it by the total, then multiply that value by 100, then round it off. I also take the floor value so that 99.7% doesn't round up to 100 since it's not truly complete yet.

    for($i=1;$i<=count($yourArray);$i++) {
      $percentage = floor(round( (($i / total) * 100), 1 ));
    }
