What does these symbol means in PHP?

Question

All these arrows symbols seems weird to me :S.

something like this

->

>

$rs->Fields("myfield");

$conn->Open......

what does the arrow > and -> means?

Please explain

Answer 1

Basically that means that you want to use something within the class.

$rs->Fields("myfield");

What that's doing is running the member function of Fields in the class that was constructed to $rs.

Same thing for $conn, it's essentially using items within a class.  It's used to get variables too so let's say there is a public variable that's set in the class and you want to access it.  You can use $rs->last_insert_id; (if of course there is a variable named last_insert_id).  It will give you the value of that variable.

Take care,
