In addition, you can use the system's own function string number_format ( float number [, int decimals [, string dec_point, string thousands_sep]] ):

Example:

echo number_format('169856420'); 
Copy after login

The output will be: 169,856,420

echo number_format('1000000',2); 
Copy after login

The output will be: 1,000,000.00

echo number_format('1000000',2,',','.'); 
Copy after login

The output will be: 1.000.000,00
