Different use of number_format() function
1. Basic number format
First we use the number_format() function with one argument to format a number with the default thousand separator. Run the following PHP script.
1 2 3 4 5 6 7 8 9 10 11 | <?php $num = "20000000"; echo number_format($num); // Output: 20,000,000 $num1 = "125467.56897"; echo number_format($num1); // Output: 125,468 ?> |
2. Decimal number format
Now, we use the number_format() function with two arguments with the default thousand separator and decimal value
1 2 3 4 5 6 | <?php $num = "454656.4567"; echo number_format($num, 2); // Output: 454,656.46 ?> |
3. Using separator
At last we check passing all parameters in the number_format() function. In the following example , is used for the decimal point and # is used for a thousand separators.
1 2 3 4 5 6 | <?php $num = "454656.4587"; echo number_format($num, 2, ',', '#'); // Output: 454#656,46 ?> |

1 2 3 4 5 6 | <?php $num = "454656.4269"; echo number_format($num, 3, '.', ''); // Output: 454656.427 ?> |
