Stupidly simple question

[Ausx]

I've been looking around for this but can someone please enlighten me as to what the '->' operator does?

Such as

$var1 -> $var2

Thanks.

$class->variable

or

$class->function()

is part of classes and how to get variables and functions within them.

[mjax]

This operator references a member variable of function/method of a class instance.

E.g:
$object->var
$object->function_call()

Outside of classes, I have also seen this syntax when using the mysql_fetch_object() function:

PHP.net wrote:

<?php
mysql_connect("hostname", "user", "password");
mysql_select_db("mydb");
$result = mysql_query("select * from mytable");
while ($row = mysql_fetch_object($result)) {
   echo $row->user_id;
   echo $row->fullname;
}
mysql_free_result($result);
?>
