Analysis of how PHP uses the number_format function to intercept decimals, number_format decimal

The example in this article describes how PHP uses the number_format function to intercept decimals. Share it with everyone for your reference, the details are as follows:

Everyone knows that you can use PHP's number_format() function to group numbers into thousands. But it will round the numbers. Is there any way to make it directly discard the decimals after the reserved digits without rounding? Don’t worry, please 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!
