User-Defined Functions
Defining functions in PHP is accomplished using the ``function keyword, followed by the function name and comma delimited arguments, surrounded by parenthesis:
function myFunction(arg1, arg2) { ... } |
If the function is encapsulated in an object, you may specify the visibility of the function, public, protected or private.
class MyClass { public function myFunction(arg1, arg2) { ... } ... |
Unlike languages, such as Perl or Python, PHP member functions implicitly extract their parent into the $this variable.
