functions, which returns changes

[Sonnich]

Geee cannot remomber

I'd like to do this:

function blabla(var $something_to_b e_updated)
{
$something_to_b e_updated++;
}

but it is not var. How do I do this?

Is there a better way than a function for this?

Re: functions, which returns changes

I'm not sure what you mean

$something_to_b e_updated;

function update() {
global $something_to_b e_updated;
$something_to_b e_updated++;
}

or

function update($somethi ng_to_be_update d) {
return $something_to_b e_updated++;
}

Re: functions, which returns changes

Note the var.
I want to pass on a variable, which is changed in the subroutine.

so::

$i = 54;
blabla($i);
$i is is now 55

You want this:

function blabla(&$someth ing_to_be_updat ed) {
$something_to_b e_updated++;
}
