Delete the last Char of a PHP String

Question

My Problem : i cant delete the last char of a string :

  foreach($_POST['checkbox'] as $item)
{
    $string .= $item.', ';
}

$markte=rtrim($string ,", ");

This should work fine. Can you post the exact code and the value of the variable before and after? — jeroen, Jan 22 '18 at 13:56
Please post input data and what expected outcome you want. It seems that your code will work. BTW you can go for `implode()` for a better solution — Alive to die - Anant, Jan 22 '18 at 13:57
you have to first declare `$string` variable as empty . i execute this code and found its working . — saddam, Jan 22 '18 at 13:59

Better use php implode function:

$string = implode(', ', $_POST['checkbox']);
