What is '->' ?

[7thGuest]

I've noticed a lot of PHP scripts use this:

->

(eg: $newuserid = $vbulletin->userstats['newuserid'];)

What exactly does it do?

[Colin F]

It's used in classes, though I'm not sure what it's actually called :)

I did take a look at that - but I'm not too up on OOP.
The manual doesn't seem to explain it, and I can't work it out exactly from the examples...

Please can anyone elaborate?

Not only classes, basically when working with objects.



$browser = get_browser();

echo 'Cookies are '. ($browser->cookies ? 'supported' : 'not supported');



$query = mysql_query("SELECT * FROM table");

while ($row = mysql_fetch_object($query))
{
echo $row->fieldname;
}


I don't know how to call it either... maybe arrow operator?

True; it's called the arrow operator:
