php数字格式值999999但输出显示10000000

Question

I try to use php number_format to show number like this xxx,xxx,xx.xx .

When I echo value it auto increment from 9999999 to 10000000.

Anyone has idea how to show data result 9,999,999?

<?php echo number_format(99999999,2); ?>

Answer 1

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

So, with your example:

<?php echo number_format(9999999, 2, '.', ','); ?>

Outputs:

9,999,999.00

Or if you did not want the decimals:

<?php echo number_format(9999999, 0, '.', ','); ?>

Outputs:

9,999,999

From php.net:

This function accepts either one, two, or four parameters (not three)

Just a reminder.
