There are multiple ways to format numbers in PHP. Here are some common methods:

  1. Number formatting with number_format function: The number_format function is used to format a number with grouped thousands and decimal places. Here's an example: $number = 1234567.89; echo number_format($number, 2, '.', ','); // Output: 1,234,567.89 In the example above, the number_format function takes three arguments: The number to format. The number of decimal places. The character to use as the decimal point. The character to use as the thousands separator.
  2. Currency formatting with money_format function: The money_format function is used to format a number as a currency. However, note that this function is only available on systems that support the underlying C library's printf function with the %n format specifier. Here's an example: $number = 1234.56; echo money_format('%i', $number); // Output (depending on the system's locale): $1,234.56 In the example above, the money_format function takes two arguments: The format of the output (%i represents the currency format). The number to format.
  3. Custom number formatting with sprintf function: The sprintf function can be used to format numbers by using custom format specifiers. Here's an example: $number = 1234.56; echo sprintf('%01.2f', $number); // Output: 1234.56 In the example above, %01.2f is a custom format specifier that represents a float number with one digit before and two digits after the decimal point.


These are just a few examples of number formatting in PHP. Depending on your requirements, you can combine these functions or use other methods to achieve different formatting effects.
