Core PHP Programming: Using PHP to Build Dynamic Web Sites

Function Declarations

As previously stated, functions should have a comment block explaining what they do and their input/output. The function block should align starting at one tab from the left margin unless the function is part of a class definition. Opening and closing braces should also be one tab from the left margin. The body of the function should be indented two tabs.

<php
        /*
        ** doAdd
        ** Adds two integers
        ** Input:  $a, $b
        ** Output: sum of $a and $b
        */
        function doAdd($a, $b)
        {
              return(a+b);
        }
?>
