I've got a block of code which was written a while ago and I'm looking to document, but one of the functions has an output parameter - how should a phpDoc-block be written to specify that a parameter is an output parameter?
Note - this isn't "I love output parameters" or "I want to use them", it's "They were used, how are they documented?" :P
Just in case I've got the name of them wrong, something like this:
function foo (&$bar)
{
$bar = 1;
return 2;
}
$varIs2 = foo($varIs1);
echo $varIs1; // 1
echo $varIs2; // 2
