将逗号添加到提取的值

I have a database where I need to store the price of items. Now when I get the values from the database, I would like commas added for the thousand value e.g convert 19000 to 19,000.

<?php echo $row['pprice'];?>

How can I change the format?

You can try using this.

echo number_format($row['pprice']);

Not sure if its correct but wont hurt to try and see if it works.

Or create a new variable for the $row['pprice'] so like this.

$commaPrice = $row['pprice'];  
echo number_format($commaPrice);

$newNumber = number_format($number);

I suggest to use money_format:

$number = 1234.56;
setlocale(LC_MONETARY, 'it_IT.UTF8');
echo money_format('%i', $number) . "
";

Note that you need to specify your current locale. If you want to use different locales than yours, you must build them install them on the operating system.
