## Rounding A Number To Nearest The Thousand In PHP

I have previously talked about rounding numbers in PHP, but what if you wanted to round the number to the nearest thousand?

It is possible to do this with the native round() function in PHP by using a negative number as the second parameter. The round() function has two parameters, the first is the number to be rounded and the second is the number of places to round the number to, also known as the precision. The default for round() is to round the number to the nearest whole number, by using positive numbers as the second parameter you can set the number of decimal places to round the number to. Giving a negative number as the second parameter will allow you to round the number to the nearest full number. For example, to round a number to the nearest thousand you can put -3 as the precision, this will change the number 12,345 into 12000.
