[SOLVED] what is the propose of ->

[riddhi]

When should one use -> in php what is its purpose?

[trq]

It is used to access an objects methods and properties.

[dooper3]

it refers to the use of php classes. Classes can contain many functions, so if you see something like:

 

$dog->needs

 

The code refers to the function $needs (note no $ sign before $needs though) within the class $dog.

 

I'm quite a noobie to classes myself, so maybe slightly wrong!

 

They're useful for grouping common functions and doing object oriented programming (OOP).

 

Google for more info, it's a big topic!

[riddhi]

what should be the exact term for searching??

[trq]

A simple example maybe?

 

<?php

 class foo {

   public a;

   public function __construct() {
     $this->a = 'this is a property';
   }

   public function b() {
     return 'this is a method';
   }

 }

 $foo = new foo;
 echo $foo->a;
 echo $foo->b;

?>

[dooper3]

do a google search for "php classes" (KEEP the quote marks), you could add "+tutorials" for good measure (without the quote marks on that bit!).
