How to remove trailing comma after final number in while loop

Question

Trying to remove the comma that comes after the number 10. Tried every plausible workaround, but nothing's worked so far.

$i = 0;

while($i < 10) {
echo ++$i. ",";
}

It is an infinite loop. Can you show exact code to increase value of $i; — Ankur Mishra, Feb 24 '20 at 18:08
Forgot to add the ++$i which is in the example, I just forgot add it here. — Stanislav Matveyevich, Feb 24 '20 at 18:12

Don't use a loop in the first place. Use implode() to insert a delimiter between array elements.

echo implode(',', range(1, 10));

Thanks, man! And duly noted about not using loops to achieve this result! – Stanislav Matveyevich Feb 24 '20 at 18:11

You can do it using loop and rtrim() like this:

$i = 0;
$result = '';
while($i < 10) {
  $result .= ++$i. ",";
}

echo rtrim($result, ',');
