overload

[sde]

i wish you could overload functions in php.

Hurts readability though. But since that isn't a concern with PHP (mod me as a flamer if you must, but PHP isn't really that nice to look at), I am suprised they didn't include it.

lol .. depends who's code you're reading.

just do:

function doSomething0(int a);
function doSomething1(string k);
function doSomething2(object o);

sure i could do that .. but then it would be 3 different functions .. and not overloading.

your example would not work if the function i wanted to overload was the constructor of a class. =/ i want overloading in php!!

oh, also php isn't sensitive to the variable type .. so it wouldn't really matter for one argument .. just if you were using different amounts of multiple arguments.

PHP Code:

<?
function blah($foo, $bar = "")
{
  echo "foo is $foo\n";
  if($bar != "")
  {
    echo "$bar is here too\n";
  }
}

blah("asdf");
blah("fdsa", "jkl;");
?>

hmm ... good point .. but it's still not the same as making different functions based on what parameters are sent ..

.. although , . i suppose you can test for the second variable and make a different function depending on its value ..

however, what if there is more than 1 pre-defined variable in the argument, you can't determine what variable is being sent .. i mean what if the second variable you send is null, and the third is not .. it only works inline like that.

i suppose ultimately php would have to be data type sensitive .. which would make us give up a lot of little luxuries.
