Everyone knows how to use PHP The number_format() function can group numbers into thousands. But it will round the numbers. Is there a way to make it directly discard the decimals after the reserved digits without rounding? Don't worry, everyone, listen to me in detail, If you want to keep two decimal places, you can change your number to -0.005

For example:

123456.6588

The result you want is:

123,456.65

You can do this:

$num=123456.6588;
echo number_format($num-0.005,2, ".", ",");

If you just want to keep integers, you can

$num=123456.6588;
number_format($num-0.5);

Problem solved!
