PHP uses the Number_format function to intercept decimals to analyze _php techniques

This example describes how PHP uses the Number_format function to intercept decimals. Share to everyone for your reference, specific as follows:

You know you can use PHP's Number_format () function to group numbers by thousand. But it rounded up the numbers, so is there a way to get it to discard the decimal number immediately after the reserved bit without rounding? Please don't worry, and listen to me carefully, if you want to keep two decimal digits, you can put your number -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 only want to keep integers you can

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

The problem is done!
