[SOLVED] Question I Should Know The Answer To

[phpQuestioner]

What does this operation do:

 

$variable->anothervariable

 

I have seen then in for loops.

 

Will this operation work in PHP 4 and if not what is there an alternative to this?

 

I know this seems like a stupid question, but I have just seen this operator/expression before and I wondered what it was and what it did.

 

I have seen this done like this:

 

<?php

for(i = 1; i <= $variable->anothervariable; i++)
{
// loop here
} 
?>
