can someone explain what -> is

[JustinB]

can someone explain what -> is and its meaning

 

example $display->header();

[dotBz]

i guess it's used to identify a member variable or function of a class

[BlueSkyIS]

it is used to invoke a class function or to retrieve a public class variable.

$obj->method(); = a method call

 

A method = a function of an object

A object = a collection of methods/functions (among other things)

 

<?php
//A function
function my_function {
    print 'hi';
}

//Run function
my_function();

//A class with a function (called a method)
class my_object {
    function my_method() {
        print 'hi';
    }
}
$obj = new my_object;

//Run method
object->my_method();

?>
