Warning: number_format () expects parameter 1 to be double

I get Warning: number_format() expects parameter 1 to be double errorin my code

$tbl->addRow();
$tbl->addCell($name);
$tbl->addCell('$' . number_format(doubleval($price), 2,',', ' ') );

I know that the price of $ value is a value of 15.00, which is a number. How can this be fixed?

Perhaps doubleval () returns some kind of error, because the number "15.00" is in the European format instead of the standard one. Have you tried using "15.00" instead?
