Re: &$ in functions

Hi guys,

at present I´m editing some old scripts from a colleague from mine. In
one function I fund something I didn´t understand. The function looks
like:

function foobar(&$val, $key = ' ')
{
...
}

Could anyone tell me what the &$ stands for? I tried to find some
informations in Google. But it is really difficult to find some
informations by using "php + &$" as a search string.

By using this, you can allow your function to modify the referenced
variable.
