在PHP中乘以十进制数

Question

From my database I get a decimal like, 25.30.

In PHP I multiply the decimal like this, 25.30 * 6. The result is 151,8 but with a comma.

The problem is that the result gets me a comma instead of a point like 151.8.

Is there a solution to solve this and get the result with a point?

Answer 1

You want to format your number. From the manual:

string number_format ( float $number , int $decimals = 0 , string $dec_point = '.' , string $thousands_sep = ',' )

So for example in your case this would be:

print number_format($number, 1, '.', ',');
