Question

i want to make a variable when transforms 1k or 1,5k into 1000 or 1500

i tried preg_replace but i doesn’t work for me becasue it adds “000” to number so i’d get 1000 and 1,5000

thank you

Answer 1

function expand_k($str) {
    // If the str does not end with k, return it unchanged.
    if ($str[strlen($str) - 1] !== "k") {
        return $str;
    }

    // Remove the k.
    $no_k = str_replace("k", "", $str);
    $dotted = str_replace("," , ".", $no_k);

    return $dotted * 1000;
}    

$a = "1k";
$b = "1,5k";

$a_expanded = expand_k($a);
$b_expanded = expand_k($b);

echo $a_expanded;
echo $b_expanded;

Outputs “1000” and “1500”. You can see for yourself here.
