I see these in PHP all the time, but I don't have a clue as to what they actually mean. What does -> do and what does => do?
->
=>
And I'm not talking about the operators. They're something else, but nobody seems to know...
=> is used in associative array key value assignment. Take a look at Arrays.
-> is used to access an object method or property. Example: $obj->method().
$obj->method()
