How to Format Number Functions in PHP
The PHP programming language has many built-in functions that allow you to shape the way data is displayed to the user. This is very useful given that PHP is traditionally used in websites, and formatting data correctly is very important for web development. One very useful data formatting function is "number_format," which sets the number of decimal places a number displays, the decimal point symbol, and the thousands-place separator. This function is very simple to use and provides a wealth of number formatting options.
