[SOLVED] Explain ->

[blackcell]

Hello all,

I have been programming in PHP for a short while.  Four months would be an accurate count.  I usually mess with it on a daily basis at work and have created multiple programs that depend on pulling, manipulating, and displaying data from a mysql database.  I am barely familiar with oop and classes but wish to learn more.  This leads me to the ultimate question that has had me wondering all day. What exactly is "->"?

I see it in classes and in gnuPHP and I am curious if it has to do with OOP in PHP.  I would also like to know more about OOP in php and would like to know if anybody has any good online OOP with PHP reads.

 

Thanks in advance.

Yes, it's for Objects.  You can probably find more info in the OOP forum here.

It's an ascii arrow. In C++, it was use to reference a property of a class you had a pointer to, in PHP, it is just used for objects properties.

And methods.

eg;

 

<?php

  class simple {

    public $a = 'foo'; // property

    public function b() { // method
      return "Hello!";
    }

  }

  $obj = new simple();
  echo $obj->a;
  echo $obj->b();
